Terminal Tightening Torque: R housings size <= 22: 53 inlb (6Nm)
R & U housings size 23/24: 133inlbs (15Nm)
U housings sizes > 24: 221inlbs (25Nm)
Ground nut on R & U housings: 89inlbs (10Nm)
2.5 Connection of the power circuit
If the supply voltage is connected to the motor
terminals, the unit will be destroyed!
Pay attention to the supply voltage 230/480V
and the correct polarity of the motor!
See technical data in Section 2.1-2.2 to match the wiring diagram to inverter size and housing type.
