1120 V 20 A AC (shown) Receptacle RC5 and/or GFCI1

2120 V 20 A AC GFCI (shown) Receptacle RC6 and/or GFCI2

3240 V 50 A AC Receptacle RC11

RC5 / 6 and GFCI1 / 2 supply 60 Hz single- phase power at weld/power speed. Recep- tacle configuration varies depending on machine model and serial number.

Maximum output from these receptacles is 2.4 kVA/kW.

If a ground fault is detected, GFCI Reset button pops out and receptacle does not work. Check for faulty equipment plugged in receptacle. Press button to reset GFCI receptacle.

.At least once a month, run engine at

weld/power speed and press test but- ton to verify GFCI is working properly.

RC11 supplies 60 Hz single-phase power at weld/power speed. Maximum output from RC11 is 10 kVA/kW.

4Supplementary Protector CB4

5Supplementary Protector CB6

6Supplementary Protector CB5

CB4 protects RC6 / GFCI2 and CB6 pro- tects RC5 / GFCI1 from overload. If a sup- plementary protector opens, the receptacle does not work. Press button to reset.

Supplementary protector CB5 protects re- ceptacles and the generator winding from

overload. If CB5 opens, the receptacles do not work. Place CB5 switch in On position to reset circuit breaker.

.If a supplementary protector continues

to open, contact Factory Authorized Service Agent.

.Generator power decreases as weld output increases.

Combined output of all receptacles is limit- ed to the 10 kVA/kw rating of the generator.

EXAMPLE: If 15 A is drawn from each 120 V receptacle , only 26 A is available at the

240 V receptacle:

2 x (120 V x 15 A) + (240 V x 26 A) = 10.0 kVA/kW
