Ground Cable Connection

Assemble the ground cable as shown in Figure 4. The ground
cable is connected to the front (see Fig 4, #10) of the machine.
Plug the cable into the receptacle and twist clockwise until tight.

Connect the ground clamp as close to the workpiece as possible.
This will reduce the possibility of current loss through stray
paths.  Always connect the clamp to clean, bare metal.  Do not
connect the ground clamp to the piece which will be cut off.

Electrical Connection

All electrical connections should be performed by a qualified
electrician in accordance with the National Electrical Code and
local codes and ordinances.  When connecting your plasma
cutter, the yellow-green wire MUST BE CONNECTED TO
GROUND, OR SERIOUS INJURY OR DEATH MAY RESULT!

ELECTRICAL SHOCK CAN KILL!  Do not connect an input
wire to the ground terminal.  Do not connect the ground
(yellow-green or green) wire to an input (hot) line terminal.  
It is also strongly recommended that a fusible line disconnect
switch be installed in the input power circuit to the plasma
machine.  This would provide a safe and easy method to
remove all electrical power from your plasma system whenever
it is necessary to perform internal inspection or servicing.

BEFORE ATTEMPTING TO MAKE ANY PRIMARY POWER
CONNECTIONS TO YOUR PLASMA CUTTER, BE SURE
THAT ALL POWER IS OFF BY OPENING THE LINE
DISCONNECT SWITCH.

Your Micro Cut 380 has been designed to operate from 220 volt
single phase power wired for a minimum of 16 amps.  The
green or yellow-green wire must be connected to ground.  The
blue and brown wires must be connected to the hot legs of the
220-volt power.
