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 or
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 cur-
rent. 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
