Maintenance
To maintain constant availability and operational reliability, we recommend that you carry out regular
visual and functional tests on the UPS as well as inspecting the battery charge status. A log should be
kept for verification. The fans must be replaced every 45,000 operating hours.
CAUTION:
Maintenance work must sometimes be performed when the UPS is connected to the power
supply. Always observe the safety regulations and secure the work area!
6.2.1
Visual inspection
During visual inspections, check for:
Unusual noises or odours
Mechanical damage or foreign bodies in the unit
Conductive dirt or dust deposits inside the unit
Accumulations of dust that affect heat dissipation
Fault messages in the display
The intervals between visual inspections depend first and foremost on the conditions in the location
where the devices are installed.
6.2.2
Function test
The functional testing of the UPS should be performed every six months and involves the following
tasks:
Activate the manual bypass
Disconnect the UPS and check the following functions when restarting the system:
•
Displays (fault messages)
•
Correct start-up of all modules
•
Check output and battery voltages
6.2.3
Battery inspection
If the UPS is out of operation for a prolonged period, maintenance-free batteries must be recharged at
three-monthly intervals. Please observe the battery manufacturer's instructions!
CAUTION:
Acid vapours emitted in the battery compartment can cause burns upon contact with body
parts and when inhaled.
The applicable protective measures must be complied with in
accordance with the safety regulations of VDE 0510, Part 2.
The following items must be measured and logged every three months:
Battery voltage between B+/N and B-/N
If possible, the voltage of the block batteries, otherwise of the battery racks
The voltage of all block batteries must be measured and logged on an annual basis. The firmness of all
screw connections must be checked annually. All checks must be performed in accordance with DIN
43539 Part 1. Special checks, such as those in accordance with DIN VDE 0108, must also be observed.
Additional testing by means of automatic testing equipment is not permitted except with the written
approval of the battery manufacturer.
NOTE:
If the battery voltage is not within the stated range and/or the battery cannot be charged
successfully, please inform our Technical Support Service and if necessary have the battery
replaced by our specialists.
