1 WARNINGS
Before attempting any work on the control board (connections, maintenance), always turn off power.
Install, upstream of the system, a differential thermal breaker with adequate tripping threshold.
Connect the earth lead to the appropriate terminal.
Always separate power cables from control and safety cables
(push-button, receiver, photocells, etc.). To avoid any electric
noise, use separate sheaths or a shielded cable (with earthed
shield).
