Panasonic Corporation - Panasonic M41A1G4L Operating Instructions Manual

Handling instructions
Wiring to motor
• Wiring work should be performed by qualified electrician.
• Turn off power and remain off until the wiring is completed.
Grounding (earth ground)
• Positively connect the equipment to the ground.
• Use only the grounding screw provided on the product. Tighten the screw with a toque of 1.2 N·m to 1.5 N·m
(recommended).
• For grounding a motor with seal connector, connect the connector internal ground terminal to the earth.
• Use screw, spring washer and flat washer made of stainless steel or copper alloy in the grounding circuit.
• Use round terminal as grounding terminal. Do not use U-shaped terminal.
Earth terminal screw
<Precautions>
Round ground terminal and grounding leadwire, and grounding screw, spring washer and flat washer on the ground
return circuit should be prepared by the customer. Earth grounding leadwire should be of size ø1.6 mm (2 mm
more.
Leadwire
Don't forcibly bend, pull or pinch motor leadwires.
Connection
• Connections or joints of motor leadwires, power cable and capacitor should be made using soldering, connector or
crimping terminal, whichever suitable, and should be covered with appropriate insulating material.
• Clamp the motor leadwires on the equipment at stable area so that the leadwires are kept stress free.
