Electrical installation, control cables
Control cables must be screened/armoured. The
screen must be connected to the frequency converter
chassis by means of a clamp. Normally, the screen
must also be connected to the chassis of the control-
ling unit (use the instructions for the unit in question).
In connection with very long control cables and ana-
logue signals, in rare cases depending on the instal-
lation, 50/60 Hz earth loops may occur because of
noise transmitted from mains supply cables. In this
connection, it may be necessary to break the screen
and possibly insert a 100 nF capacitor between the
screen and the chassis.
