Item 2 Extra protection
If you want extra protection, pay attention to the
following:
As extra protection, error voltage relays or neutral
grounding can be used. However, the installation
must comply with local health and safety standards.
An earth fault can introduce a direct current in the
discharge current. Any ELCB relay used must comply
with local regulations. The relays must be suitable to
protect three-phase equipment with bridge rectifier
and short discharge on power-up.
Item 3 Motor, mains and brake cables
To comply with the stated EMC emission
specifications, screened motor cable must
not be
used. However, a precondition is that an RFI filter
module is installed to comply with the EMC emission
specifications.
Observe the following max. cross sections for motor,
mains and brake cables:
