g Digital Energy™ LP Series 1 - Important Safety Instructions 1.1 Save these instructions This manual contains important instructions that should be followed during installation and maintenance of the UPS and batteries. It also gives all necessary information about the correct use of the UPS.
g Digital Energy™ LP Series • It is important that the unit has adequate ventilation. Maintain air movement around and through the unit. Do not block the air vents. • Avoid placing the unit in direct sunlight or near heat sources. • Do not plug household appliances such as electric heaters, toasters or vacuum cleaners into the UPS. The UPS output is intended to be used only for electronic loads such as computers and telecommunications equipment.
g Digital Energy™ LP Series 2 - Introduction 2.1 Description More than ever before, today's advanced electronic equipment, with complex integrated circuits and other sensitive electronics, needs a stable and continuous AC power supply to operate correctly. While the power coming from the wall outlet is often unreliable, a GE Digital Energy™ LP-U UPS provides the security of completely uninterrupted power.
g Digital Energy™ LP Series 3 - Functional Explanation 3.1 The Principles of Operation The UPS stores electric energy in batteries. This allows the UPS to supply output power even when the incoming utility power is cut off completely. Energy is stored as Direct Current (DC), while input and output energy must be Alternating Current (AC). Therefore the UPS contains an input converter (AC to DC) and an output converter (DC to AC). (fig.2) 3.
g 3.4 Digital Energy™ LP Series Automatic Bypass Switch If the output converter is unable to deliver the demanded output power because of overload or overtemperature, the automatic bypass switch will automatically transfer the load to the utility. When the situation is corrected the UPS will switch back to normal operation, i.e. the load is tranferred back to the output converter.
g Digital Energy™ LP Series 4 - Installation 4.1 Transport NOTE: Transport the UPS only in upright position. Check for sufficient floor and elevation loading capacity. Move the UPS in its original package to the final destination room. Do not stack other package on top. 4.2 Unpacking Cut the two wrapping bands, and remove the shipping box. Loosen the four bolts with which the UPS is fixed to the pallet. Remove the UPS from the pallet.
g Digital Energy™ LP Series • Ensure that the total power requirement of the equipment to be protected does not exceed the rated output power of the UPS. (output power for your unit is indicated on the rating label on the rear panel). • When using the 120V split phase outputs make sure that the load per 120V output does not exceed half the rating. • The UPS may only be installed by trained personnel.

g Digital Energy™ LP Series 4.5.6 LP 11U series: 2 / 3 / 4 parallel operating units – additional info The RPA option (Redundant Parallel Architecture) allows you to create a redundant UPS system in which 2, 3 or 4 LP-U units operate in parallel. The following should be considered when installing units in parallel. This section gives aditional information on: - installation (4.5.6.1) - start-up (4.5.6.2) - use / maintenance (4.5.6.3) 4.5.6.1 Notes concerning installation of a parallel system 1.
g 5. Digital Energy™ LP Series The right option slot (14) at the rear of the unit contains the the RPA-card. Before the parallel system can be put into operation a unique number has to be appointed to each UPS in the system. This can be 0, 1, 2 or 3. Start with 0 for the first unit, 1 for the second, 2 for the third and 3 for the last unit: - loosen the screws, remove the RPA-card - set the dipswitch to the appointed number (fig. 18) - re-install the RPA-card, fasten the screws.
g Digital Energy™ LP Series 4.5.6.3 Notes concerning use / maintenance of a parallel system ECO-mode: If LP-U units operate in parallel, the ECO-mode feature is not available. No-load shutdown: If LP-U units operate in parallel, the no-load shutdown function is not available.

g 5.2 Digital Energy™ LP Series Start-up The numbers between (brackets) refer to figure 19 in section 5.1. Note: the UPS can be started on battery power if the utility input voltage is not available or if circuit breaker ‘utility’ is in off-position: simply skip step 1. To prevent accidental discharging of the batteries, it is however recommended to proceed with step 1 and start the unit only when the utility input voltage is available. 1.
g 5.3 Digital Energy™ LP Series Use Once the unit is in operation, there is no need to switch the unit on/off during use. If the manual bypass switch (rear panel, 10) is in position '1', switching off by the on/off switch (rear panel, 7) results in a total absence of the output voltage (also the bypass voltage) of at least 5 secs. If an emergency shutdown switch has been installed (see 4.5.1.1-2, step 6) the UPS will stop immediately when the switch is opened.
g Digital Energy™ LP Series 5.3.2 Status and Alarm Menu The UPS alerts the user with a standard alarm screen that the operating mode has changed and/or that an alarm situation occurs: ON LINE ALARM PRESS UP The actual operating mode, the possible modes are mentioned below. The lower line -if displayed- shows that an alarm occurred. More information can be retrieved with the 'up' key. If no further information is available, the second line is blank.
g Digital Energy™ LP Series BATTERY CHARGER NO FLOAT After 24 hours of charging time, the battery voltage did not reach the normal float voltage. This may be caused by faulty batteries, too many battery packs connected or a charger fault. CAPACITOR C1 CAPACITY LOW The main DC-capacitor needs replacement due to aging or failure LOADnotPROTECTED INVERTER OFF Due to a failure the output converter's output is not available. As a result the load may have been transferred to bypass.
g Digital Energy™ LP Series INPUT AND OUTPUT NOT SYNCHRONIZED BATTERY RUNTIME LEFT 0:09:41 The output converter frequency is not synchronized to the utility (input) frequency. In this situation the automatic bypass switch is not able to transfer the load from output converter to bypass and reverse: automatic bypass operation is inhibited: if for whatever reason the output converter is unable to deliver the required output, output power is lost. (see section 3.5).
g Digital Energy™ LP Series TSTAMP 6028773 Q4 1 FREQ RANGE: NO LOAD : 2% 1 QUICK BATTERY TEST PRESS ENTER CALIBRATE BAT PRESS DOWN+ENTER Service information on internal timer. Frequency tracking range: output converter frequency will follow the bypass frequency within these limits before returning to its own internal frequency. Standard setting: nominal ±2%. Can be changed into nominal ±4% or ±6%. See 5.3.4 Set-up Menu.
g Digital Energy™ LP Series 5.3.4 Set-up Menu To enter the set-up menu: 1. Be sure the UPS is switched off. 2. Press push-button 'Enter/Reset' (front panel) and then turn switch ‘UPS on/off’ (rear panel) into position ‘on’ (up). Keep Enter/Reset pressed until set-up menu appears. Using push-buttons 'up' and 'down' you can scroll through the several set-up screens, 'Enter/Reset' confirms a screen choice.
g Digital Energy™ LP Series AUTOMATIC BYPASS ENABLED Controls functioning of the automatic bypass switch. Range: ENABLED/DISABLED. If the UPS is used as a frequency converter you may change the setting to ‘DISABLED’. Bypass operation will then be inhibited and all alarms related to ‘bypass out of limits’ are suppressed. SERVICE WARNING DISABLED The system can prompt for service to a user defined schedule. Range: 8/12/16/20/24/28 months or DISABLED.
g Digital Energy™ LP Series 5.4.3 Deep Battery Test The runtime as shown on the LCD screen is calculated, and the value is initially based on the capacity of new batteries. As batteries age, their capacity deteriorates, and as a result the initial battery capacity may be too unreliable for a proper runtime prediction. The UPS is able to keep track of the aging process, if a 'deep battery test' (battery calibration test) is executed regularly.
g 5.5 Digital Energy™ LP Series Other Features 5.5.1 Shutdown 'Remote shutdown': Using communication capabilities, the computer can direct the UPS to turn itself off following controlled shutdown of the system. Subsequently the UPS will remain off for at least a few seconds (see also 6.1). LED 'operation' will blink green. The unit will start up again as soon as the utility returns.
g 5.5.5 Digital Energy™ LP Series ECO-mode The UPS is equipped with the ‘ECO-mode’ feature. If the feature is enabled, the load is operated on utility through the electronic bypass switch. If the utility is interrupted or out of limits the load is automatically transferred to the inverter. Operating the load on utility improves the efficiency of the UPS with 5-8% and saves on energy costs. We advise not to use the ECO-mode in case of an unstable utility.
g Digital Energy™ LP Series 6 - Interfacing Features The UPS is equipped with 3 ‘option slots’ (rear panel, 12-14). In the most left slot (12) an RS232/contact interface card is factory installed. See 5.1. In the middle slot (13) additional Relay or SNMP plug-in Cards can be installed. The most right slot (14) allows easy installation of an RPA plug–in Card (Redundant Parallel Operation). 6.
g Digital Energy™ LP Series 7 - Optional Features 7.1 Extended Runtime Extended runtime versions are equipped with additional separate battery packs to increase the runtime of the unit. Additional batteries will increase the recharging time for the unit. All other operational information is the same. If a battery pack is connected, the UPS must be informed about the new total battery capacity to allow a reliable recalculation of the available run time. Please refer to section 5.3.4 ‘Set-up Menu’.
g 7.4 Digital Energy™ LP Series PDM: Power Distribution Module This Power Distribution Module (PDM) contains 4 x Nema 5-20R, 2 x Nema L6-30R and 1 x Nema L14-30 R Power sockets (see fig. 23). The PDM replaces the conduit box (17), and converts the LP-U into a pluggable UPS. Only qualified personnel is allowed to install the PDM. For more information please refer to the user manual that comes with the Power Distribution Module.
g Digital Energy™ LP Series 8 - Maintenance 8.1 General When used properly, the UPS is virtually maintenance free other than keeping the air inlets/outlets free from dust. 8.2 Cooling fan The expected operational life of the cooling fans is approximately 20,000 to 40,000 hours of continuous operation. A high ambient temperature will shorten this operational life. 8.
g Digital Energy™ LP Series 9 - Troubleshooting Whenever a malfunction occurs, first check external factors (e.g. connections, temperature, humidity or load) to determine whether the problem is caused by the unit itself or by its environment. Subsequently check whether the breakers/switches on the rear panel (fig. 19, 7-8-9) are in ‘on’ position. Always check these external factors before concluding that your UPS is faulty.
