3-7. Electrical Service Guide For 230 VAC

.
The Auto-Linet circuitry in this unit automatically adapts the power source to the primary voltage being applied. Check input voltage available
at site. This unit can be connected to any input power between 120−230 VAC without removing the cover to relink the power source.
.
Actual input voltage should not exceed ± 10% of indicated required input voltage. If actual input voltage is outside of this range, output may not
be available.
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda-
tions are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source.

1 If a circuit breaker is used in place of a fuse, choose a circuit breaker with time-current curves comparable to the recommended fuse.
2 "Time-Delay" fuses are UL class "RK5" . See UL 248.
3 "Normal Operating" (general purpose - no intentional delay) fuses are UL class "K5" (up to and including 60 amps), and UL class "H" ( 65 amps and
above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.
