SECTION 3
Before making any connections to
the power source output termi-
nals, make sure that all primary in-
put power to the machine is de-en-
ergized (off) at the disconnect
switch.
A poor connection or failure to con-
nect work cable to workpiece can
result in fatal shock.
Failure to connect the workpiece to
earth ground will result in the open-
ing of FUSE F3 and CIRCUIT BREAKER
CB1, disabling the console.
3. Safety codes specify that the Power Cable GROUND wire be the last to
break connection should the cable be pulled out of the unit. Be sure to cut
and strip wire as shown in Figure 6.

4. Thread the input conductor cable from the wall disconnect switch through the
strainrelief in the rear panel of the main contactor (MC). Connect the primary
power leads to the main contactor terminals (see Figure 7) using UL listed
pressure wire connectors. Also connect the ground wire to the stud provided
on the chassis base inside the left-rear of the cabinet. Secure the input cable
by tightening the strain relief coupling.
