Therefore:
m
Do not touch before taking into account the discharge time of the capacitors and
electrically live parts.
m
Heed corresponding notes on the equipment.
m
If additional capacitors are connected to the intermediate circuit, the intermediate
circuit discharge can take a much longer time. In this case, the necessary waiting
period must itself be determined or a measurement made as to whether the equip-
ment is de-energized. This discharge time must be posted, together with an IEC
60417-5036 (2002-10) warning symbol, on a clearly visible location of the control
cabinet.
