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. 1/N). The motors comply with
DIN EN 60034 and are in protection class IP 55
and insulation class F. The appropriate connec-
tion 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 frequency, permitted current
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 pro-
tection switches with delayed switch off, de-
pending 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
