Connection
INFO
The device may only be connected up and secured by a
trained person, taking into account the "rated voltage"
and "rated current" specified on the nameplate.
A fuse corresponding to its rated voltage (max. 3 x IB
according to lEC 60127-2-1) or a motor protection switch
with short-circuit and thermal instantaneous release
(setting to rated current) must be upstream of each
electric motor. In the case of very low rated currents of
the electric motor, the fuse with the lowest current value
according to the specified IEC-standard is sufficient. The
fuse must be housed in the associated power supply unit
or separately upstream. The fuse rated current must be
the same as or greater than the specified maximum
working voltage of the electric motor. The breaking
capacity of the fuse link must be the same as or greater
than the maximum short-circuit current expected at the
place of installation (normally 1500 A). A connection box
with a melting fuse can be used for example.
Additional equipotential bonding is required. The
terminal block designated for this purpose has the
ground sign.

Commissioning
If the electric motor was installed according to the
guidelines specified under section Installation and
section
no foreign bodies can reach the rotating components,
then the electric motor can be switched on.
A thermal safety fuse is integrated that disconnects the
motor from the mains for reasons of explosion protection
in the event of external heating or blockage. This also
occurs if these installation instructions are not complied
with.
We recommend a thermostat upstream at temperatures
ranging from 40°C.
