Do not open the unit, there are no user serviceable parts inside. CAUTION There may be damage to the equipment if procedures and practices are not strictly observed and followed.
Digital Energy 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.
Digital Energy 3 INSTALLATION 3.1 PACKAGE CONTENTS The UPS shipping box contains: VH Series UPS 4 plastic support parts Mounting set 1 plastic front panel 2 plastic plugs 2 mounting brackets and screws 1 USB cable 1 CD ROM with UPS monitoring software (see 5.3) and its manual This manual REPO Connector (see 4.4.13) Inspect the UPS for damage after unpacking. If any damage is present please immediately notify the carrier and place of purchase.
Digital Energy 3.3 INSTALLATION PREPARATIONS 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 Vertical installation - preparations NOTE Please consider the weight of the UPS. Lift the unit with the help of a second person. 1. Place the UPS horizontally on a table or desk. 2.
Digital Energy 3.3.2 Rackmount installation - preparations NOTE Please consider the weight of the UPS prior to installation to ensure the rack is capable of supporting the weight. We recommend that the UPS is placed in its lower half. Fit the unit into the rack cabinet with the help of a second person. 1. Place the UPS horizontally on a table or desk. 2. Install the two mounting brackets that came with the unit using the screws provided. 3. Connect the DC connector of the internal batteries. 4.

Digital Energy 3.5 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 3.6. 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.
Digital Energy 3.6 CONNECTIONS 3.6.1 Connecting interface devices If you do not want to use the communication capabilities of the UPS, please skip this section and proceed with 3.5.2. The UPS is equipped with two interface ports: a USB port and an RJ11 port, allowing advanced communication between the UPS and a computer (network). Refer to section 5 for more detailed information. . 3.6.
Digital Energy 4 OPERATION 4.1 OPERATING PANEL 1 3 4 5 6 2 7 8 Fig. 4.1: Operating panel switch / LED main function 1- ‘on’ switch switches on the UPS, starts quick battery test (see 4.
Digital Energy 4.2 START-UP 4.2.1 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.
Digital Energy 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.
Digital Energy 4.4.1 Standby The UPS output is off, but the batteries are charging, see 3.5.2 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.
Digital Energy if the bypass function has been disabled (see 4.5), or if the UPS operates on battery (see 4.4.4). To avoid these problems, be absolutely certain that the power demands of the protected equipment are within the limits of the UPS. 4.4.8 Battery bad Either the batteries are almost chemically worn out or the battery wiring, including the battery fuse, is faulty. If the batteries are aged, they must be replaced as soon as possible to ensure full protection for your equipment.
Digital Energy 4.5 USE: SETUP MODE 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 Press keypad 'O' and keep it pressed while pressing 'I' simultaneously. Release both buttons. The setup sequence starts with the setup of the output voltage, indicated by a blinking LED ‘operation’.
Digital Energy 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 'battery bad' alarm will be generated (see 4.4.8). Batteries have to be replaced as soon as possible.
Digital Energy 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.
Digital Energy 6 MAINTENANCE 6.1 SAFETY DANGER When the UPS operates, all parts of the electronics are directly connected to the utility and high voltages are present on all internal parts, including the battery. Even after disconnection from the utility, all parts inside the UPS, including the battery, conduct dangerous voltages (except the RJ11 and USB output). For your safety, only authorized service personnel may remove the cabinet cover. Refer to section 1.2 for further details. 6.
Digital Energy 7 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. 3.4a/b) and be sure that the UPS is not overloaded. The following chart is a simple troubleshooting checklist only.
