1.1  Save these instructions 

 

This manual contains

 

important instructions for the 

Digital Energy™ GT Series-UL

 

UPS that should be followed during installation and maintenance of the UPS and the 
batteries. 

 

Before attempting to install and start up the UPS, carefully read this 
manual. Keep this manual next to the UPS for future references. 
All servicing must be done by qualified personnel. Do not attempt 
to service the UPS unless you have had proper training. 

 

WARNING:

 By opening or removing covers you run the risk of 

exposure to dangerous voltages !

 

 

While every care has been taken to ensure the completeness and accuracy of 
this manual,  GE  accepts no responsibility or liability for any loss or damage 
resulting from the use of the information contained in this document. 
This document shall not be  copied nor reproduced without the permission of 
GE. Due to technical improvements, some of the information contained in 
this manual may be changed without notice. 

 

1.2  General 

 

 

CAUTION

: RISK OF ELECTRIC SHOCK.

  

  The UPS has an internal battery supply, with a nominal voltage of (UPS rating / 

voltage): 1kVA / 36Vdc,  1.5kVA / 72Vdc, 2kVA / 72Vdc,  3kVA / 72Vdc. 

  The appliance outlets may be electrically live, even when the UPS is disconnected 

from the utility supply. Dangerous voltages may be present during battery operation. 

  Do not open the unit, there are no user serviceable parts inside. 

  The batteries must be disconnected during maintenance or service work. 

  The UPS contains potentially hazardous voltages. 

 

1.3  Installation  

 

  The unit should be installed by service personnel. 

  To reduce the risk of electric shock, install this UPS in a temperature and humidity 

controlled indoor area free of conductive contaminants.  

  Ambient temperature must not exceed 40°C (104°F). Optimal battery lifetime is 

obtained if the ambient temperature does not exceed 30

°

C (86

°

F). 

  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. 

  The UPS should only be powered from a 2-pole 3-wire grounded wall outlet. This 

outlet must be easily accessible and located near the UPS.  

  Do not use extension cords when connecting the UPS to the utility power supply.  

  The AC output of  the UPS needs a disconnecting switch such as a breaker which 

has to be provided by others. 

  The overcurrent protection for the output AC circuit has to be provided by others. All 

of our UPS have an electronic protection of AC output short circuit. 

  Avoid spilling liquids on or dropping any foreign object into the UPS. 

  Do not plug a laser printer or household appliances such as electric heaters or 

vacuum cleaners into the UPS. The UPS output is intended to be used only for 
electronic loads such as computers and telecommunications equipment. 

  Upon installation, it should be ensured that the sum of the leakage currents of the 

UPS and the connected loads does not exceed 3.5mA.  

  The unit should be operated by properly trained personnel.
