g Digital Energy™ GT Series 2 - Installation 2.1 Package contents The packing box contains a Digital Energy™ GT Series-UL UPS, an RS232 data cable, a CD ROM and this manual. Carefully inspect the packing box and its contents. If any damage is visible please immediately notify the carrier and/or dealer. 2.2 Location Please refer to section 1.3 of ‘IM PORTANT SAFETY INSTRUCTIONS’ 2.3 Rear panel 9 5 8 7 9 3 7 6 5 3 3 8 6 2 2 1 1 1500 / 2000 / 3000 VA 1000VA Fig. 2.
g 2.4 Digital Energy™ GT Series Installation The unit should be installed by service personnel. IMPORTANT: Before making any connection and switching on the UPS, please check the following conditions: • your mains supply is 100/110/120 Volts and 50/60Hz, • the total power demand of the connected equipment does not exceed the rated output power of the UPS (indicated on the rating label). 2.4.1 Stable placing of 1.
g 2.4.3 Digital Energy™ GT Series Connecting the RS232/dry contact interface Connect the interface signal cable between the RS-232/dry contact port on the rear panel of UPS and COM1 or COM2 of your computer if necessary. See fig. 2.4. Refer to chapter 4 for more information. 2.4.4 Connecting the load 1. Calculate the total power consumption of your loads to ensure that the UPS is able to supply the required power and overload condition will not happen. 2.
g Digital Energy™ GT Series Fig. 2.5 Stand-by mode Though the batteries (the internal energy reserve) were fully charged when the UPS left the factory, they might have lost some energy during transport and/or storage. It is recommended to allow the UPS to recharge the batteries for at least 6 hours. This way you ensure that the UPS can provide sufficient runtime in case of a utility power failure. 2.4.
g Digital Energy™ GT Series 3 - Operation 3.1 Operation Panel 8 13 12 11 10 7 9 2 1 Fig. 3.1 Operating panel 4 6 3 5 1 Switch ‘I/TEST’ - Switches on the UPS - In ‘ON-LINE’ mode it starts the battery test - In ‘ON BATTERY’ mode it mutes the buzzer 2 Off switch Switches off the UPS 3 LED ‘Bypass’ The UPS is in ‘BYPASS’ mode: the incoming utility power is channeled directly to the load. See also 3.3.5 4 LED ‘Line’ Indicates the condition of the utility input power.
g Digital Energy™ GT Series 3.2 Start-up 3.2.1 Start-up, utility power available 1 Push the ‘I/TEST’-button (1) and hold for 3 seconds until a short beep is heard. The bypass LED will shortly light up. When the LED ‘On Line’ lights up, the UPS is running in ‘ON LINE’ mode. 2 The equipment connected to the UPS can now be switched on. Fig. 3.2 On Line mode 3.2.
g Digital Energy™ GT Series 3.3.4 Silencing the buzzer When the UPS is in ‘ON BATTERY’ mode the buzzer can be turned on or off by pressing the ‘I/TEST’-button (1). 3.3.5 Switching off 1 To switch off the UPS push the OFF -button (2) until a short beep is heard. Release the button after the beep. After a few seconds the UPS will be in ‘STANDBY’ mode: it will continue keeping the batteries charged. See also fig. 2.5.
g 3.4.4 Digital Energy™ GT Series Bypass operation If the UPS is unable to deliver the demanded output power due to overload or over-temperature, the load is switched directly to the utility supply. The LED ‘Bypass’ will light, and the buzzer will sound continuously. The UPS will switch back to ‘ON LINE’ mode (normal operation) when the load and/or temperature conditions returned to normal. If a power failure occurs during bypass Fig. 3.
g Digital Energy™ GT Series 4 - Communication 4.1 Description The GT Series UPS is equipped with a communications interface, providing RS232 and dry contact protocols in one sub -D 9-pin female connector located at the rear of the unit. The communication port on the UPS can be connected to a computer. This port allows the computer to monitor the UPS status and control the operation of the UPS in some conditions.
g 4.2 Digital Energy™ GT Series RS232 The RS-232 communication port provides the following functions: 1 - Monitoring charger status 2 - Monitoring battery status and condition 3 - Monitoring inverter status 4 - Monitoring UPS status 5 - Monitoring the AC utility power status 6 - Turn on/off UPS on schedule for power saving 7 - Adjust transfer voltage Pin Assignment: Pin 2 : PC receives line RS-232 data from UPS. Pin 3 : PC transmits line RS-232 data to UPS. Pin 5 : Signal ground.
g 4.4 Digital Energy™ GT Series SNMP Plug-in Card (optional) SNMP (Simple Network Management Protocol) is the most popular protocol in the network. Via NMS (Network Management Station) you can detect the status of all facilities in the network. An SNMP Interface Card can be plugged into the built-in SNMP slot on rear panel of the UPS (please refer to fig. 2-1). This optional interface unit can integrate the UPS into the network allowing you to easily monitoring the UPS status.
g Digital Energy™ GT Series 5 - Optional Features Apart from the SNMP-option described in 4.4 the following options are possible: 5.1 Extended Runtime Extended runtime can be obtained by connecting a separate battery extension module to the UPS. The additional batteries increase the runtime and recharging time for the unit, all other operational information is the same as for standard models. 5.2 TVSS (Transient Voltage Surge Suppressor) RJ-45/RJ-11 Surge Protector.
g Digital Energy™ GT Series 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 and be sure that the UPS is not overloaded. The following chart is a simple troubleshooting checklist only.
