Procedure
Hazardous voltage!
Ensure there is no live voltage before carrying out service or maintenance work on the
transfer switching equipment.
We recommend actuating the 3KC4 and 3KC8 transfer switching equipment at least once a
year in the following sequence:
I - 0 - II - 0 – I.
This should be done both in manual operation and in automatic mode with the 3KC8 transfer
switching equipment and in remote mode with the 3KC4 transfer switching equipment.
In addition, all connections should be tested at least once a year to make sure they are tight.
The procedure is as follows:
● Check the tightening torque of the connecting screws
● Visual inspection of all cables
● Visual inspection of accessories and their connections
