1. SAFETY
If this is not so, the cross-sectional area of the protective earthing conductor must be determined in a manner that produces
a conductance equivalent to that which results from the application of this table.
• 2.5
㎟
if there is mechanical protection, and
• 4
㎟
if there is not mechanical protection. If you have cord-connected equipment, make sure that the protective earthing
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 earthing conductor.
1.5 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.
1.6 USING AN RCD OR AN RCM DEVICE
The drive can cause a current in the protective earthing 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.
CAUTION!
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.
