INITIAL SETUP
Optional Field Wiring
In the event the current location has an 1PH, 3 Wire plus Ground, 30 Amp electrical receptacle, the
machine power cord/plug (PN 46908.0002) will need to be removed and replaced with a power cord
and plug to match the current location receptacle configuration.
• 208/240VAC circuit (voltage range +5/-10%)
• Dedicated 30-amp circuit: cord cap, receptacle, and breaker
• Determine the available on-site electrical receptacle is 1PH, 2 Wire plus Ground or 1PH, 3 Wire plus Ground.
• Machine is supplied with a power cord (PN 46908.0002) AWG 10/3 30A/250V
with Plug L1, L2, G for use with 1PH, 2 Wire plus Ground receptacle.
NOTE: (N) no neutral wire/conductor used.
• If location electrical receptacle is a 1PH, 3 Wire plus Ground receptacle, see the attached Optional Field
Wiring decal on the machine and the following “Example” below.
• Remove supplied power cord and install AWG 10/4 30A/250V power cord with correct plug to match location
receptacle configuration.
NOTE: (N) Neutral wire/conductor (White Wire) from the power cord will need to be capped off in the
machine.
• Use the appropriate size of wire nut inside the machine over the power cord Neutral Wire (White) end and
push into the wire while twisting the nut clockwise. See Example.
• Receptacle within 4.5 feet (1.4 meters) of the machine.
NOTE: The length of the power cord is regulated by the machine’s UL certification.
• Machine total amp draw 24.0 amps at 208VAC
