Control Circuit Wiring Precautions
Consider the following precautions for wiring the control circuits.
• Separate control circuit wiring from main circuit wiring and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC (contact output) from wiring
to other control circuit terminals.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating
faults.
• Ground the cable shields with the maximum contact area of the shield and ground.
• Cable shields should be grounded on both cable ends.
• If flexible wires with ferrules are connected they might fit tightly into the terminals. To
disconnect them, grasp the wire end with a pair of pliers, release the terminal using a
straight-edge screw driver, turn the wire for about 45
and pull it gently out of the termi-
nal. For details, refer to the Technical Manual. Use this procedure for removing the wire
link between HC, H1 and H2 when the Safe Disable function is utilized.
