WARNINGS
Important: 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 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-button, receiver, photocells, etc.). To avoid any electric
noise, use separate sheaths or a shielded cable (with earthed
shield).
