7.2 Safety instructions for the Hybrid Cabinet Bushing
WARNING
Electric shock due to the residual charge of the DC link capacitors
Because of the DC link capacitors, a hazardous voltage is present for up to five minutes after
the power supply has been switched off.
Contact with live parts can result in death or serious injury.
● Do not remove/insert the hybrid connector until 5 minutes has elapsed.
● Before starting any work, also check that the system is in a voltage-free state by measuring
at the DC link terminals DCP and DCN.
WARNING
Electric shock due to high leakage currents caused by an interrupted external protective
conductor
Drive components conduct high discharge currents via the protective conductor. Touching
conductive parts when the protective conductor is interrupted can result in death or serious
injury.
● Ensure that the following protective conductor connection paths are available:
– Via the hybrid cable.
– Via the PE connection. In this case, the protective conductor cross-section must be ≥4
mm
2
.
Each of these connections must be suitable as a protective connection.
NOTICE
Damage through use of incorrect DRIVE-CLiQ cables or hybrid cables
Damage or malfunctions can occur on the devices or system if incorrect or unapproved
DRIVE-CLiQ cables or hybrid cables are used.
● Only use suitable DRIVE-CLiQ cables and hybrid cables that have been approved by
Siemens for the respective application.
