Installation
5.5 Connecting the motor
GEFAHR
Danger of death if the electrical installation has
not been done professionally.
The electrical installation may only be done by a spe-
cialist electrician observing EN 60204. The operating
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 plug-connector (Fig. 2/J)
if fi tted or via the motor protection switch (for
safety reasons, a motor protection switch is
required and the connecting cable must be in-
stalled 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
