Motor connection, shield support and fabrication
4.1 Motor plug connector for Motor Modules 3 A ... 30 A
Opening the terminals/releasing the motor cables
To release the terminals, press the individual locking levers up using a slot-head screwdriver
(0.8 x 4 mm) until the lever snaps back into the motor connector casing.
If it is difficult to withdraw the conductors from the open terminal, it may help to press the
locking lever up as far as it will go while withdrawing the conductor. This action opens the
spring-loaded terminal to its maximum.
Note
We do not recommend manual release of the terminal due to the high forces that need to be
applied.
Connecting conductors to connectors with screw terminals
Starting with W2, V2, U2, insert the conductors into the open terminals.
Ensure that the conductors are inserted as far as they will go.
For larger cross-sections, it is helpful if U2, V2, W2 are simultaneously inserted and secured
by screws.
Tighten the screws with a torque of 0.5-0.6 Nm (4.4 lbf in). Screwdriver: Slot-head 0.8 x 4
mm.
