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.
