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.
