Precautions for Safe Use
• Use crimp terminals for wiring.
• Do not connect bare stranded wires directly to terminals.
Additional Information
Do not allow wire clippings, shavings, or other foreign material to enter any Unit. Otherwise,
Unit burning, failure, or malfunction may occur. Cover the Units or take other suitable counter-
measures, especially during wiring work.
