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. It also gives all necessary information about the correct use of the UPS. Before attempting to install and start up the UPS, carefully read this manual. Keep this manual next to the unit for future references.
2 - Introduction 2.1 Introduction The GE (General Electric) Digital Energy VH Series UPS, a truly on-line uninterruptible power supply, protects your equipment from all forms of power interference, including complete power failures. 2.2 Intended use • Uninterruptible Power Supplies (UPS) are designed to protect sensitive electronic equipment such as computers and telecommunications equipment from all forms of power interference, including complete power failure.
3 - Installation 3.1 Package contents The shipping box contains a VH Series UPS, four plastic support parts + mounting set, plastic front panel, two plastic plugs, two mounting brackets and screws, a USB cable, two IEC male-female power cords, 1 mains power cord (VH Series 3000VA only), a CD ROM and this manual. Inspect the UPS for damage after unpacking. If any damage is present please immediately notify the carrier and place of purchase.
3.3 Installation procedure The UPS can be used in a stand alone tower format using the two supporting stands (section 3.3.1), or can be mounted in a 19 inch rack using the two mounting brackets (section 3.3.2). All required items are included in the delivery. 3.3.1 1. If you want to install a battery pack as well, please read section 3.3.4 step 1-2 first, then proceed with step 2 below. 2. Place the UPS horizontally on a table or desk. 3.
3.3.2 1 Rackmount installation - preparations Place the UPS horizontally on a table or desk. 1 2 2. Re-position the operating panel: remove the 2 screws that hold the panel and rotate the panel 90 degrees counterclockwise. Don’t pull out the panel! Tighten the 2 screws again. 3. Install the two mounting brackets that came with the unit using the screws provided. 3 4. Connect the DC connector of the internal batteries. 4 5.
3.3.3 Rear panel The figures on this page show a VH Series 3000 VA. The differences with the rear panel - configuration of other models is clearly indicated in the text below. 1 Input socket AC mains supply to the UPS 700-2000 VA: smaller socket than shown here 2 Input breaker Protects the UPS from damage caused by high input currents 700-2000 VA: breaker has lower rating than shown here 5 3 Appliance outlets - max. rating 10A To connect the loads to the UPS.
3.3.4 Installation of a battery extension pack With a battery extension pack you can increase the battery runtime of the UPS. If you do not install a battery extension pack please skip this section and proceed with 3.3.5. 1 Before installation, check whether the nominal voltage of the battery pack is suitable for the UPS: the voltage mentioned on the label on the battery drawer of the UPS and the one on the rear panel of the battery extension pack (36 Vdc or 72 Vdc) should match. 2.
6. Adjust the orientation of the “operating panel” in case of rackmount use: loosen the 2 screws that hold the panel and reinstall it in reversed position. 7. Assemble the plastic front panel (like in 3.3.2 step 5). 8. Using the DC socket of the battery pack you can install a second, third, etc. pack. See chapter 6 for more information. 6 8 fig. 3.3.4b: installing battery extension pack(s) to the UPS modifications reserved OPM_VHE_XXX_0K7_3K0_XGB_V010 10 User manual VH Series 700-3000 UPS 1.
3.3.5 Connecting interface devices If you do not want to use the communication capabilities of the UPS, please skip this section and proceed with 3.3.6. The UPS is equipped with two interface ports: a USB port and an RJ 11 port, allowing advanced communication between the UPS and a computer (network). Refer to chapter 5 for more detailed information. 3.3.6 Connecting power and load 1 Switch off your computer, and unplug it from the socket-outlet.
4 - Operation 4.1 Operating panel 1 3 4 5 6 fig. 4.1: operating panel 2 7 8 switch / LED main function 1- ‘on’ switch switches on the UPS, starts quick battery test (see 4.
4.2 Start-up 4.2.1 1 2 Start-up, mains available Via front panel: press keypad 'I' (1, fig. 4.1) briefly; LED ‘operation’ (already slowly blinking) will at first blink faster and after a few seconds it will illuminate continuously, indicating that the unit has started up. Via UPS monitoring software: startup after delay, see 4.4.11 for more information. The equipment connected to the UPS can now be switched on. 4.2.
4.4 Use: status and alarm indications o status indications the operating mode ! low priority alarms abnormal operating situations !! high priority alarms situations in which the actual output voltage of the UPS is no longer guaranteed; immediate action should be taken Indicators on front panel (fig. 4.1) Situation o Standby (4.4.1) - - - o Startup pending (4.4.11) ----- o Normal operation (4.4.2) ⎯⎯⎯ !! On bypass (4.4.3) ⎯⎯⎯ o On battery (4.4.4) ⎯⎯⎯ ⎯⎯⎯ !! Battery low (4.4.
4.4.1 Standby The UPS output is off, but the batteries are charging, see 3.3.6 step 5 4.4.2 Normal operation See 4.3.1. 4.4.3 On bypass The UPS is equipped with an automatic bypass switch. This switch automatically transfers the load to the mains if the UPS is unable to deliver the demanded output power due to overload or overtemperature. If all 4 load LEDs illuminate, bypass operation is caused by an overload.
4.4.7 Overload The demanded power exceeds the normal capacity of the UPS. The alarm occurs when the load is > 100%. If the load exceeds 150% the UPS will immediately switch to bypass, assuming that the conditions for a transfer to bypass are fulfilled. If an overload condition between 110-150% persists, the UPS will also switch to bypass operation.
4.5 Use: setup mode In the setup-mode the following parameters can be changed: • output voltage: 220 / 230 / 240 Vac • bypass: enable / disable (see 4.4.6) • P (Phase) - N (Neutral) reversal indication: enable / disable (see 4.4.12) • output frequency: 50 / 60 Hz The setup mode can only be entered if the UPS is in ‘standby’ -mode: connected to a live wall outlet and switched off (LED 'operation' blinks). 1 2 3 4 Press keypad 'O' and keep it pressed while pressing 'I' simultaneously. Release both buttons.
4.6 Battery management Maximum battery life and reliability are obtained by the following features: • Quick battery test The quick battery test checks whether the batteries and their wiring are healthy. If a quick battery test shows that the batteries are close to being worn out, a 'replace battery' alarm will be generated (see 4.4.8). The batteries must be replaced as soon as possible (see 7.4).
5 - Communication 5.1 USB port The USB port is a plug-in interface port which enables advanced communication between the UPS and the computer (UPS software required). The interface port is operative as soon as the mains power cord is plugged into a live wall outlet, even if the UPS is switched off. For more information please refer to the user manual that comes with the interface software.
6 - Option: extended runtime (VH Series 1000-3000) Extended runtime can be obtained by connecting a separate battery extension pack to the UPS. In this case the UPS must be informed about the new total battery capacity to allow a reliable recalculation of the available runtime (please contact your dealer). Dependent of the charge condition of the new batteries the new runtime calculations may temporarily be unreliable.
7.4 Batteries 7.4.1 General The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the number of discharge cycles. As a healthy battery is critical to the performance of the UPS, an automatic quick battery test is performed regularly to ensure failsafe operation (see section 4.6). When the condition of the battery is critical, a 'replace battery' alarm will be activated (see 4.4.8). Replace the batteries as soon as possible, proceed with section 7.4.2.
8 - 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 the thermal circuit breaker: it may be tripped. If so: reset it (see fig. 3.3.3 a/b) and be sure that the UPS is not overloaded. The following chart is a simple troubleshooting checklist only.
