Wiring Section 5-3
Crimp Terminals The terminals on the Power Supply Unit are M4, self-raising terminals with
screws. Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Tighten the terminal block screws to the torque of
1.2 N·m. Use round-type crimp terminals (M4) having the dimensions shown
below.
!Caution Tighten the AC power supply terminal block screws to the torque of 1.2 N·m.
Loose screws may result in short-circuit, malfunction, or fire.
Note 1. Supply power to all of the Power Supply Units from the same source.
2. Do not remove the protective label from the top of the Unit until wiring has
been completed. This label prevents wire strands and other foreign matter
from entering the Unit during wiring procedures.
3. Do not forget to remove the label from the top of the Power Supply Unit af-
ter wiring the Unit. The label will block air circulation needed for cooling.
