4. INSTALLATION
Ensure that the mains power supply specifications match the voltage specified on the data plate
of the electrical panel and connected motor, then provide an earthing connection before all other
connections.
The power line must be protected by a residual current circuit breaker.
Tighten the electrical cables on the corresponding terminals using a suitable tool correctly sized to
avoid the risk of damaging the fixing screws. Be extra careful if using an electric screwdriver.
The electrical panel is designed for wall-mounting using screws and plugs in the pre-drilled holes at
the corners of the enclosure, or brackets where available.
Install the equipment in areas compliant with the protection rating and ensure that the box is kept
intact when drilling the holes for fitting the cable clamps.
Avoid the use of multicore cables where there are wires connected to inductive loads and power
cables and signal cables such as probes and digital inputs.
Keep connection cables as short as possible, preventing any twisting of cables which may be harmful
due to inductive effects on the electronic equipment.
All wires used in the wiring must be suitably sized to withstand the power load.
