Requirements for grounding
Properly ground the system as follows to ensure personal safety, proper operation, and to reduce electromagnetic
interference (EMI):
The system must be grounded through the power cord according to national and local electrical codes.
Single-phase service must be of the three-wire type with a green (CSA) or green/yellow (CE/CCC) wire for the
protective earth ground and must comply with national and local requirements. Do not use a two-wire service.
Refer to the Safety and Compliance Manual (80669C) for more information.
Power cord considerations
This system ships with a CSA, CE, or CCC power cord configuration. See Exterior, rear on page 187 for part number
information.
CSA power cords and plugs
CSA configurations include the following plug and adapters.
The power cord is equipped with a NEMA twist
lock-style plug (NEMA L6-20P) appropriate for
use on a 240 V/20 A circuit with a NEMA twist
lock-style outlet.
To operate the system on a lower amperage circuit,
attach the female end of the 120 V/15 A
(NEMA 5-15P) plug adapter to the power supply’s
NEMA twist lock-style plug.
Do not set the amperage adjustment knob above
20 A, or you may trip the circuit breaker. See Adjust
the gas pressure and output current on page 44.
To operate the system on a 240 V/20 A circuit,
attach the female end of the 240 V/20 A
(NEMA 6-50P) plug to the power supply’s NEMA
twist lock-style plug.
