1.4 Batteries  
· NOTE: Servicing of batteries should be performed or supervised by personnel  
knowledgeable of batteries and the required precautions. Keep unauthorized  
personnel away from batteries.  
· When replacing the batteries, use only the same number, type and size battery:  
GP1270-F2 (CSB) or NP7-12(YUASA) or HR1234W F2(CSB).  
· Avoid charging in a sealed container.  
· CAUTION:Never dispose of batteries in a fire. The batteries may explode.  
· CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the  
skin and eyes. It may be toxic. If exposed to electrolyte, wash immediately with  
plenty of water.  
CAUTION: A battery can present a risk of electrical shock and high short circuit  
current. The following precautions should be observed when working on batteries:  
- Remove watches, rings or other metal objects.  
·
- Use tools with insulated handles.  
- Wear rubber gloves and boots.  
- Do not lay tools or metal parts on top of batteries.  
- Disconnect charging source prior to connecting or disconnecting battery  
terminals.

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.  
2.4.6 Checking the site wiring fault LED  
When the UPS is still in ‘STAND-BY’ mode, check the site-wiring fault LED. If the UPS  
is plugged into an improperly wired AC utility power outlet, this LED flashes as shown in  
Fig 2.6.  
Fig. 2.6 Site wiring fault  
The detection of site wiring faults includes a missing ground, phase-neutral polarity  
reversal and an overloaded neutral circuit. If the LED flashes, unplug the UPS and have  
the site wiring checked by a qualified electrician.  
This step completes the installation procedure.

3.4.4 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  
operation, the UPS will switch to battery  
operation and eventually, when the batteries  
Fig. 3.9 Bypass operation  
are depleted, UPS output power is lost. If the UPS functions under overload or over-  
temperature conditions it may not be able to protect the load.  
3.4.5 Replace battery  
The batteries are aged and must be  
replaced as soon as possible to ensure fu ll  
protection for your equipment.

4.4 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.  
NOTE: Once you install the SNMP card in the UPS, you cannot get any information from  
the UPS via RS232. i.e. only either an SNMP card or the RS232 port can be used as a  
communication interface!  
The SNMP card also supports SHTTP protocol, you can use browser Microsoft IE or Netscape  
Communicator to monitor or configure the UPS. Besides, the SNMP card supports Telnet and  
FTP for remote monitoring and firmware upgrading.  
Specifications:  
1 - Auto detecting 10/100M Network speed.  
2 - Supporting protocol: TCP/IP, UDP, HTTP, ICMP, ARP, TELNET, BOOTP, DHCP, FTP  
and SNMPv1.  
3 - Remote firmware upgradeable and configurable.  
4 - Web server built-in, allow monitoring/controlling UPS via browser.  
5 - VT100 terminal mode or Telnet to configure SNMP.  
Functions:  
1 - Schedule: Shutdown/Restart UPS, testing and control outlets.  
2 - Testing: Scheduled testing of the battery can insure that the UPS will operate properly  
during a utility power failure.  
3 - Event log: Auto-record the power event.  
4 - Historical records: Keep records of UPS status in specified interval.  
5 - Event handling: configure special action for each power event to meet your requirements.  
6 - On/Off UPS: set-up the power on/off timer.  
7 - Outlet control: configure UPS outlets.

5 - Optional Features  
g
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.  
To prevent damage caused by surges, noise and spikes traveling over the telephone line or  
network line.  
6 - Maintenance  
6.1 General Maintenance  
Apart from battery servicing, the UPS is virtually maintenance free. Take care of proper  
environmental conditions and keep air inlets/outlets free of dust. Please read 1.3.  
6.2 Batteries - General  
The service life of the battery is from 3 to 6 years, depending on the operating conditions  
(mainly temperature and number of discharge cycles).  
As a healthy battery is critical to the performance of the UPS, it is advised to regularly perform  
a battery test to ensure failsafe operation (see section 3.3.3). When the condition of the battery  
is critical, a 'replace battery'alarm will be activated (see 3.4.5). Have the batteries replaced as  
soon as possible. See 6.3.  
6.3 Batteries - Replacement  
·
·
WARNING: first read the safety rules in sections 1.1, 1.2 and 1.4.  
Servicing of batteries should be performed or supervised by personnel  
knowledgeable of batteries and the required precautions. Keep unauthorized  
personnel away from batteries.  
6.4 Recycling the UPS at the end of service life  
GE Digital Energy, in compliance with environment protection recommends that the  
UPS equipment, at the end of its service life, must be recycled conforming to the local  
applicable regulations.

7 - Troubleshooting  
g
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. If the suggested solution does  
not succeed, or if the information is insufficient to solve the problem, please contact your dealer
