YProperly install and ground this equipment according to its Owner’s Manual and national, state, and local codes.

.Customer-supplied equipment is re- quired if generator will supply standby power during emergencies or power out- ages.

1Utility Electrical Service

2Transfer Switch (Double-Throw)

Switch transfers the electrical load from electric utility service to the generator. Trans- fer load back to electric utility when service is restored.

Install correct switch (customer-supplied). Switch rating must be same as or greater than the branch overcurrent protection.

3 Fused Disconnect Switch

Install correct switch (customer-supplied) if required by electrical code.

4 Welding Generator Output

Generator output voltage and wiring must be consistent with regular (utility) system volt- age and wiring.

Connect generator with temporary or perma- nent wiring suitable for the installation.

Turn off or unplug all equipment connected to generator before starting or stopping engine. When starting or stopping, the engine has low speed which causes low voltage and frequency.

5 Essential Loads

Generator output may not meet the electrical requirements of the premises. If generator does not produce enough output to meet all requirements, connect only essential loads (pumps, freezers, heaters, etc. − See Sec- tion 12-4).

Notes

Work like a Pro!

Pros weld and cut safely. Read the safety rules at the beginning of this manual.
