Electrical Power Connections
CAUTION
Make sure power is disconnected at the main power source and at the
operator’s electrical disconnect switch before proceeding.
Secure all electrical power connections inside the power wiring compartment. Use the
electrical wiring diagram supplied with this unit.
All single phase operators will have – L1 (neutral), L2 (hot) and ground. All three phase
operators will have – L1, L2, L3 and ground. It is very important that operator is
properly grounded.
IMPORTANT NOTE:
On three phase operators the power connections must be
properly phased. If they are phased wrong the gate operator will run
backwards. To correct this situation, disconnect power a main power source
and at the operator’s electrical disconnect switch. Then, reverse any two of the
three power leads.
