Initial Control Inspection
Danger: At this point, there should be no electrical
connection to the machine. Electrical panel must be
closed and secured. When main switch is on, there is
HIGH VOLTAGE throughout the electrical panel (including
the circuit boards and logic circuits) and some
components operate at high temperatures. Therefore,
exercise extreme caution when working in the panel.
• Set the main breaker switch at the upper right of
the electrical panel on the back of the machine to
OFF.
• Using a screwdriver, unlock the two latches on
the panel door, unlock the cabinet with the key
and open the door.
• Take sufficient time to check all the components
and connectors associated with the circuit
boards. Look for any cables that have become
disconnected, look for any signs damage and
loose parts in the bottom of the panel box. If
there are any signs that the machine was
mishandled, call the factory before proceeding.

1-Phase Machines:
Insert each power lead
into the wire cover. Connect the two power
leads to L1 and L3 terminals on top of the
main circuit breaker.
3-Phase Machines:
Insert each power lead
into the wire cover. Connect the three
power leads to L1, L2 and L3 terminals on
top of the main circuit breaker.
Connect the separate ground line to the
ground bus to the left of the terminals.
Note:
Make sure that the leads actually
go into the terminal-block clamps . (A poor
connection will cause the machine to run
intermittently or have other problems, such
as servo overloads.) To check, simply pull on
the wires after the screws are tightened.
