6.2.4 Connect Variable-Frequency Drive to Motor
• Connect the variable-frequency drive to the motor by using the wiring materials (pos.
7) delivered in the retrofit kit as follows:
Motor connection assignment
Connect all cables to the following connections:
(3) "Mains terminal [X1]"
• Unscrew the four screws from the drive control's housing cover and take off the cov-
er.
• Guide the mains connection cable through the cable screw connection and connect
the phases with the L1, L2, L3 contacts for 400 V and the ground cable with the PE
contact on the connection terminal. The cable screw connection provides strain relief,
and the PE connection cable must be connected in a leading fashion (considerably
longer)!
• When connecting a brake resistor to an optional braking module, cables with shielding
and double insulation must be used!
• The inverter drive also has the option of being equipped with terminals for connecting
a brake resistor. The configuration may vary depending on the version.
(4) "Brake resistor [X2] (optional)"
Terminal no.
