6.1 UPS and Battery Care
For the best preventive maintenance, keep the area around the UPS
clean and dust-free. If the atmosphere is very dusty, clean the outside of
the system with a vacuum cleaner. For full battery life, keep the UPS at
an ambient temperature of 25°C (77°F)
Note: The batteries in the UPS are rated for a 3-5 year service life. The
length of service life depends on the frequency of usage and ambient
temperature. Batteries used beyond expected service life will have
severely reduced runtimes. Replace batteries at least every 4,5 years to
keep units running at peak efficiency, first date is based on production
date.
6.2 Transporting the UPS
NOTE:
The internal UPS batteries MUST be disconnected before
transport.
CAUTION:
The following procedure should be performed or supervised
by personnel knowledgeable about batteries and the required precaution.
Keep unauthorized personnel away from batteries.
If the UPS requires any type of transportation, the batteries must be
disconnected (but not removed) before the unit is transported:
1. Verify that the UPS is off and disconnected from utility power.
2. Place the UPS on a flat, stable surface with the front of the cabinet
facing you.

3. Remove the UPS front cover
4. Disconnect the internal battery connectors
5. Fix the UPS front cover
6.3 Storing the UPS and Batteries
If you store the UPS for a long period, recharge the battery every 6
months by connecting the UPS to utility power. The batteries charge to
90% capacity in approximately 4 hours. However, it is recommended
that the batteries charge for 48 hours after long-term storage.
Check the battery recharge date on the shipping carton label. If the date
has passed and the batteries were never recharged, do not use the UPS.
Contact your service distributor.
When to Replace Batteries
When the status summary screen displays the UPS fault icon with the
“Service Battery” alarm and the audible alarm sounds continuously, the
batteries may need replacement. Contact your service representative to
change or order new batteries.
6.4 Testing Batteries
For a battery test, please check:
l
The batteries must be fully charged.
l
The UPS must be in Normal mode with no active alarms.
l
The load must be higher than 10%.
To test batteries:
1 Connect the UPS to utility power for at least 48 hours to charge
the batteries.
2 Press the
button for one second to go to the main menu
selection and scroll down to the Control menu using the
button.
3 Press the
