Note: 1. (Heavy dotted line):Field wiring

2. Have all electric work done by a licensed electrician

according to the local regulations.

3. Earth leakage circuit breaker should be set up on the

wiring of the power supply.

4. Mark indicates terminal bed, connector.

5. Auto-restart function from power failure can be turned

on by setting SW1-9 dip switch to its ON position.

(Note:This function is not set to ON from the factory.)
