Attention: Before attempting any job on the control board (connections, maintenance), cut out electric power and the
battery.
-Install, upstream of the system, a differential thermal breaker with adequate tripping threshold.
-Always separate 230VAC power cable from control and safety cables (push-buttons, receiver, photocells, etc.). To avoid
any electric noise, use separate sheaths or a shielded cable (with earthed shield).
