Step 1:Removethefrontpanel(11athead
screws).
Step 2: Feed the power cord through the
strain relief in the bottom of the
machine.
Step 3: Attach the wire ends to the terminal
block.
Step 4: Attach the ground wire to connector on
the frame cross bar.
Step 5: Check that all connections are tight.
Step 6: Tighten the strain relief and replace

L1, L2, L3, are the 3 phases
V1 = Phase to phase voltage, between any 2
phases.
V2 = Phase to neutral voltage, L1 to neutral
must be 120V.
