lugs, as well as the clearances to be observed and sufficient fastening of
the cables were checked.
During the visual inspection, .... % of the connections were checked with

Note: Connections using conical spring washers DIN 6796 are
maintenance-free and only a visual inspection is necessary during return
to service.
4.7.5 Connections to terminals have been checked using a power screwdriver
applying the correct torque. 100% of all connections made on site, random
checks at internal connections of the switchboard (e.g. control voltage
supply in cross-wiring compartment and vertical distribution, conductor
lines for electrical interlocks).
If the client specifies, for example, metal fastening elements or cable

– Secure and enduring fastening has been performed; a hazard caused
by falling plates or other conducting parts can be excluded due to their
location.
– Covers have been retrofitted because of doubts about the reliability of
the fastening and/or a possible hazard caused by falling plates or other
parts.
