Power plugs and receptacles
Plugs are shipped with the machine line cords in USA and Canada. The line cord length is 4250 mm (14
ft). Power plugs in the following table are approved for use with specified models and meet the relevant
test laboratory or country/test-house standards. The power plug must be connected to a correctly wired
and grounded receptacle. The customer is responsible for receptacle wiring.
For countries that require other types of plugs or receptacles, the system is shipped without plugs on the
line cords, and you are responsible for supplying and installing both plugs and receptacles.
Important:
In a typical three-phase power cord, there are five wires inside the cut cord cable. There are the three
phase wires, one ground wire and there is a fifth, small diameter wire, connected to the cable shield, that
acts as a drain. This drain wire must be connected to the cable ground, NOT neutral.

DC source
The DC feed is on the B line. The C and A lines are the DC return. The crimp between the C line and A
line is internal on cords with a customer plug. For cut end cords, the C and A lines must both be tied to
the negative side of the source because all four wires exit the cord body separately. Reference the
following table for DC voltage information.
