Requirements for grounding
Properly ground the system as follows to ensure personal safety and 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) 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 or CE power cord configuration. See Exterior, rear on page 203 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
Step 3 – Adjust the output current on page 45.
 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.
