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
qualified 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) or the motor data plate
(Fig. 1/P
1
). The motors comply with DIN EN
60034 and are in protection class IP 54 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 frequency, permitted current value).
b) Connect the motor via the plug connection or
a motor protection switch (for safety reasons a
motor protection switch is required and cable
fitting must be provided to provide strain relief
for the connection cable). We recommend using
motor protection switches with delayed 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
