6.3.1 Performing high-voltage testing
If high-voltage testing of the control cabinet or the power
supply as a stand-alone component is planned during final
inspection and testing, the following features must be
observed.
– The power supply wiring must be implemented as
shown in the wiring diagram.
– The maximum permissible test voltages must not be
exceeded.
Avoid unnecessary loading or damage to the power supply
due to excessive test voltages.
