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 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 connection version). The motor data must
be compared with the data of the existing mains
network (current type, voltage, network frequen-
cy, 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..
c) With more than 4 starts an hour we recommend
using a soft start device.See accessories data
