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 ope-
rating company has to provide the main switch.
a) The electrical motor data can be found on the
data plate (Fig. 2/N) or the motor data plate. 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 connec-
tion version). The motor data must be compared
with the data of the existing mains network (cur-
rent type, voltage, network frequency, permitted
current value).
b) Connect the motor via the plug connection
(Fig. 3/J) or a motor protection switch (for safety
reasons a motor protection switch is required
and cable fi tting must be provided to provide
strain relief for the connection cable). We recom-
mend using motor protection switches with de-
layed 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
