CONTROL BOARD 740 D
1. WARNINGS
Before attempting any work on the control board (connections, maintenan-
ce), always turn off power.
Install, upstream of the system, a differential thermal breaker with adequate
tripping threshold.
Connect the earth cable to the appropriate terminal on the J7 connector
of the equipment (see fig.2).
Always separate power cables from control and safety cables (push-but-
ton, receiver, photocells, etc.). To avoid any electric noise, use separate
sheaths or a shielded cable (with earthed shield).
