F Data Sheet - Electrical Connection
The motor must be connected only by an authorized electrician: The relevant local regulations must
be observed when laying the cables and connecting the motor. The installation of motor protection
equipment is mandatory. Refer to the Machine Data Sheet for the electrical values. The motor turns
in the correct direction with a clockwise rotary field.
The insulation resistance must not fall below 20 MOhm on commissioning. The insulation resis-
tance must be >= 2 MOhm for further tests. The direct measuring voltage is 1000 V.
