6.1 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.
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!
6.1.1 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 shown in the display.
The intervals between visual inspections depend first and foremost on the conditions in the location where the
devices are installed.
6.1.2 Functional 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 of the rectifier and inverter

Function of the static switch
 Check the output voltages of the rectifier and inverter as well as of the static switch
6.1.3 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 IEC 60896-21.
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.
