Omron FQM1-CM001, FQM1-MMA21, FQM1-MMP21 Grounding, Terminal Screws, Crimp Terminals

	Wiring	Section 3-2
Terminal Screws and		The terminals on the Power Supply Unit use M4, self-raising terminal screws.
Crimp Terminals

Note (1) Use crimp terminals for wiring.

(2)Do not connect bare stranded wires directly to terminals.

(3)Tighten the terminal block screws to a torque of 1.2 N·m. Use M4 crimp terminals for AC power supplies.

Crimp Terminals for AC Power Supply

7 mm max.

20 mm max.

M4 self-raising terminal screws

Tightening torque 1.2 N•m

!Caution Tighten AC power supply terminal block screws to a torque of 1.2 N·m. Loose screws may cause shorts, malfunctions, 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 Power Supply Unit until the 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 after wiring the Unit. The label will block air circulation needed for cooling.

LG (Noise-filtered neutral terminal) Ground separately with a resistance of less than 100 Ω to increase resistance to noise and to prevent electric shocks.

GR (Ground)

Ground this terminal separately to less than 100 Ω to prevent electric shock.

•GR is the ground terminal. To help prevent electric shock, ground this ter- minal to less than 100 Ω and use special ground wire (minimum cross- sectional area of 2 mm2).
