CONTROL BOARD 780D

5.1.

WARNINGS

Important: Before attempting any work on the control board
(connections, maintenance), always turn off power.
• Check local wiring codes in all cases and follow all local building
codes. Wiring and hookup should be performed by qualified
electricians/installers only.
• AC power should be supplied from a circuit breaker panel and
must have its own dedicated circuit breaker. This supply must
include a green ground conductor.
• Properly ground the gate operator to minimize or prevent damage
from power surges and/or lightning. Use a grounding rod if neces-
sary. Connect the ground cable to the PE terminal on J7 (Fig. 22),
and to the ground lug on the operator (Fig. 40). A surge suppres-
sor is recommended for additional protection.
• Always separate power cables from control and safety cables
(push-button, receiver, photocells, etc.).
