YIf unit does not have GFCI recep- tacles, use GFCI-protected exten- sion cord.

.Auxiliary power decreases as weld current increases.

1 240 V 50 A AC Receptacle RC3

RC3 supplies 60 Hz single-phase power at weld/power speed. Maximum output is 12 kVA/kW.

2120 V 15 A AC Duplex Receptacle RC2

3120 V 15 A AC Duplex Receptacle RC1

RC2 and RC1 supply 60 Hz single-phase power at weld/power speed. Maximum out-

put from RC2 or RC3 is 1.8 kVA/kW.

4240 V 30 A, AC Twistlock Receptacle RC6

RC6 supplies 60 Hz three-phase power at weld/power speed. Maximum output is 12 kVA/kW.

5 Circuit Breaker CB3

CB3 protects RC1, RC2, and RC3 from overload. If CB3 opens, RC1, RC2, and RC3 do not work. Place switch in On posi- tion to reset breaker.

6 Circuit Breakers CB1 And CB2

CB1 protects RC1 and CB2 protects RC2 from from overload. If CB1 or CB2 opens,

the receptacle does not work. Press button to reset breaker.

7 Circuit Breaker CB13

CB13 protects RC6 from overload. If CB13 opens, the receptacle does not work. Push breaker bar up to reset.

.If a breaker continues to open, contact Factory Authorized Service Agent.

Combined output of all receptacles limited to 12 kVA/kW rating of the generator.

EXAMPLE: If 13 A is drawn from RC1 and RC2, only 37 A is available at RC3:

2 x (120 V x 13 A) + (240 V x 28 A) = 12 kVA/kW
