Safety instructions for line filters

Danger to life if the fundamental safety instructions and residual risks are not heeded
Failure to heed the fundamental safety instructions and residual risks in Chapter 1 can
result in accidents causing severe injuries or death.
• Follow the fundamental safety instructions.
• Consider the residual risks on the risk assessment.
Danger to life due to electric shock in the event of missing touch protection
Death or serious injury can result when live parts are touched.
• For the line filter, use touch protection according to IPXXA or corresponding to the local
Danger to life caused by high leakage currents when the protective conductor in the line
feeder cable is interrupted
The drive components conduct a high leakage current via the protective conductor.
Touching conductive parts when the protective conductor is interrupted can result in death
or serious injury.
• Ensure that for increased leakage currents, the local regulations for protective
• Within a machine/system, ensure that the protective conductor fulfills at least one of the

installation regulations.
WARNING
conductors at the installation site are complied with.
following conditions:
For fixed connection:
– The protective conductor is routed so that it is protected against mechanical damage
along its complete length.
– As a conductor of a multi-conductor cable, the protective conductor has a cross-
section ≥ 2.5 mm² Cu.
– For an individual conductor, the protective conductor has a cross-section ≥ 10 mm²
Cu.
– The protective conductor consists of two conductors with the same cross-section.
When establishing the connection using an industrial plug connector according to EN
60309:
– As a conductor of a multi-conductor cable, the protective conductor has a cross-
section ≥ 2.5 mm² Cu.
Cables routed within control cabinets or closed machine housings are considered to
