High leakage current!
Connect 2x protective
earthing conductor
The mains voltage supply (L1, N and 2xPE) is to be
connected to terminals XE1 in accordance with the wir-
ing diagram. The phase ”L1”, the neutral conductor “N”
and one of the protective earth wires “PE” are to be led
twice through the bore of the snap ferrite “SF” supplied.
The installation of the fuse F3, the electrical isolator
“Q” (all pole disconnecting device with a minimum
contact clearance of 3 mm) and a fault current protec-
tion switch with 30 mA trigger current (by client) in the
mains supply line are mandatory.
The electrical isolator must be mounted in direct proximity
of the control unit (max. distance 50 cm) and must be
easily accessible in a height between 0.6 m and 1.9 m
(recommended: 1.7 m) .
CAUTION! Make sure the voltage indicated on the rat-
ing plate meets the local line voltage. Otherwise, do not
connect the control unit..
DANGER! When using a frequency converter there must
be TWO protective earth conductors for optimum
safety. The second protective earth wire must be
connected directly to the nearest potential equaliza-
tion. The wire cross section of both earth conductors
must comply with the local regulations. If the present
installation does not allow for two protective earth
conductors, the wire cross section of the single earth
conductor must be at least 10 mm
2
.
Note: If the control unit is connected to a mains supply
incorporating a fault current protection switch make
sure the fault current protection switch is suitable for
operation with frequency converters and their lters. If
problems should arise when operating the system in
conjunction with a fault current protection switch, please
contact your Condair representative.
