11. Technical inspections and maintenance.
Technical inspections and maintenance can be performed after disconnecting the power supply from the power
network. The PSU does not require any specific maintenance, however, its interior should be cleaned with
compressed air if it is used in dusty conditions. In case of fuse replacement, use only compatible replacement
parts.
Technical inspections should be carried out not less frequently than once per year. During the inspection, check the
batteries and run the battery test.
4 weeks after installation, re-tighten all threaded connections, see Fig. 2 [11] and Fig. 3 [2].
11.1. Battery replacement of the LCD panel.
Estimated operating time of battery type CR2032 is about six years. After this period, the battery will need to be
replaced.
Battery replacement of the LCD panel should be done during mains operation or battery-assisted operation in order
to avoid resetting the time settings.
CAUTION!
Removed batteries should be stored in a designated collection point. Do not reverse the
polarity of the batteries. Do not use batteries of different types. Improper use of the battery
may lead to explosion.
