DANGER!
Risk of fatal injury from electrical current!
Stored electric charge.
Discharge time of the modular system = discharge time of the device with the longest
DC link discharge time in the modular system.
Refer to Z Electrical Data –.
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.
