conductor must be determined in a manner that produces a conductance equivalent to that which
results from the application of this table.
The cross-sectional area of each protective grounding conductor that is not a part of the mains cable
or the cable enclosure, must be a minimum of:
•
2.5 mm
2
if there is mechanical protection, and
•
4 mm
2
if there is not mechanical protection. If you have cord-connected equipment, make
sure that the protective grounding conductor in the cord is the last conductor to be
interrupted, if the strain-relief mechanism breaks.
Obey the local regulations on the minimum size of the protective grounding conductor.
1.4
Electro-magnetic compatibility (EMC)
The drive must obey the standard IEC 61000-3-12. To obey it, the short-circuit power S
SC
must be a
minimum of 120 R
SCE
at the interface point between your mains and the public mains. Make sure
that you connect the drive and the motor to mains with a short-circuit power S
SC
that is a minimum
of 120 R
SCE
. If necessary, contact your mains operator.
1.5
Using an RCD or an RCM device
The drive can cause a current in the protective grounding conductor. You can use a residual current-
operated protective (RCD) device, or a residual current-operated monitoring (RCM) device to give
protection against a direct or an indirect contact. Use a type B RCD or RCM device on the mains side
of the drive.
NOTE!
Because there are high capacitive currents in the AC drive, it is possible that the
fault current protective switches do not operate correctly.
Do not do voltage withstand tests on the AC drive. The manufacturer has already
done the tests. Doing voltage withstand tests can cause damage to the drive.
