How to connect wiring to the terminals
◼ For strand wiring
(1) Cut the wire end with a wire cutter or wire-
cutting pliers, then strip the insulation to expose
the strand wiring about 10 mm(3/8").
(2) Using a screwdriver, remove the terminal
screw(s) on the terminal plate.
(3) Using a round terminal fastener or pliers,
securely clamp each stripped wire end with a
round terminal.
(4) Position the round terminal wire, and replace
and tighten the terminal screw using a
screwdriver.
u Precautions when laying power and ground wiring
Use round pressure terminals for connections to the power terminal block.
When laying ground wiring, you must use round pressure terminals.
When none are available, follow the instructions below.
• Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power
wiring may cause abnormal heat.)
• When connecting wiring which is the same thickness, do as shown in the figure below.
• For wiring, use the designated power wire and connect firmly, then secure to prevent outside pres-
sure being exerted on the terminal block.
• Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a small head
will strip the head and make proper tighterning impossible.
• Over-tightening the terminal screws may break them.
