SECTION 7 − OPERATING AUXILIARY EQUIPMENT

7-1. 120 Volt And 240 Volt Duplex Receptacles
4	6	3	2	5	1

YBe sure equipment connected to the 240 V receptacles is GFCI-pro- tected.

.Generator power is not affected by position of Welder Selector switch.

.4 kVA/kW generator power output is shared by all receptacles.

1240 V 20 A AC Receptacle RC1

2120 V 20 A AC GFCI Receptacle GFCI 1

3240 V 20 A AC Receptacle RC2

4120 V 20 A AC GFCI Receptacle GFCI 2

Receptacles supply 60 Hz single-phase power at weld/power speed.

If a ground fault is detected, the GFCI re- ceptacle(s) circuit opens to disconnect the

faulty equipment and the GFCI Reset but- ton pops out. Check for damaged tools, cords, plugs, etc. connected to the recep- tacle. Press button to reset receptacle and resume operation.

.At least once a month, run engine at

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

5Circuit Breakers CB1 And CB2

6Circuit Breakers CB3 And CB4

CB1 and CB2 protect RC1 and GFCI 1 from overload. If CB1 or CB2 opens, RC1 does not work. 120 volts may still be present at RC1. If CB2 opens, GFCI 1 does not work. Press button to reset breaker.

CB3 and CB4 protect RC2 and GFCI 2 from overload. If CB3 or CB4 opens, RC2 does not work. 120 volts may still be present at

190 376

RC2. If CB4 opens, GFCI 2 does not work. Press button to reset breaker.

.If a circuit breaker continues to open,

contact Factory Authorized Service Agent.

Maximum output from each 120 volt GFCI receptacle is 2.4 kVA/kW. Maximum output from each 240 volt duplex receptacle half is 4.0 kVA/kW.

Total combined output from all receptacles is 4 kVA/kW.

EXAMPLE: If 12 A is drawn from RC1, only

9 A is available at GFCI 1:

(240 V x 12 A) + (120 V x 9 A) = 4.0 kVA/kW

.Generator power is not affected by weld output.
