Installation
5.5 Connecting the motor
DANGER
Danger of death if the electrical installation has
not been done professionally.
The electrical installation must only be done by a
qualified electrician observing EN 60204. The
operating company has to provide the main
switch.
a) The motor‘s electrical data is given on the data
plate (Fig. 2/N) or on the motor data plate (Fig. 2/
P
1
). The motors comply with DIN EN 60034
and are in protection class IP 55 and insulation
class F. The appropriate connection diagram is
located in the motor‘s terminal box (not for the
plug connection version). The motor data must
be compared with the data of the existing mains
network (current type, voltage, network frequen-
cy, permitted current value).
b) Connect the motor via the plug connection or
the motor protection switch (for safety reasons,
a motor protection switch is required and the
connecting cable must be installed via a cable
fitting to provide strain relief).
We recommend using motor protection switches
with delayed switch off, depending on possible
excess current. Temporary excess current may
occur when the machine is started cold.
NOTICE
Power supply
The conditions at the installation location must match
the information on the motor data plate.
Without derating the following is permissible:
• ± 5% Voltage deviation
• ± 2% Frequency deviation
