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
qualifi ed electrician observing EN 60204. The operat-
ing 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 con-
nection version). Compare the motor data with
the data of the existing mains network (current
type, voltage, network frequency, permitted cur-
rent value).
b) Connect the motor via the motor protection
switch (for safety reasons, a motor protection
switch is required and the connecting cable
must be installed via a cable fi tting to provide
strain relief).
We recommend using motor protection switches
with delayed switch off, depending on possible
excess current. Temporary excess current can
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
