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
wiring.
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.

Level alarm signalling from probe input disabled
ON 
Level alarm signalling from probe input enabled
DIP-SWITCH 1 enables level alarm signalling from probe input or minimum level float (C-MIN-
MAX input).
In the OFF position, an input status change does not cause any alarm signal.
In the ON position, an input state change - depending on the emptying or filling function - leads
to the signalling of an alarm on the panel and the activation of the voltage-free contact alarm
output and voltage alarm output.

8.8 DIP-SWITCH 8 - Motor switching module enable
OFF 
Switching module deactivation
ON 
Switching module activation
DIP-SWITCH 8 enables automatic switching of the motors.
In OFF position, G/P1 input directly and independently controls motor output 1 and G/P2 directly
and independently controls motor output 2.
In the ON position, this function means that on each call from G/P1 the motor outputs are
activated alternately and, in the event of a simultaneous call from G/P2 input , both motors will
be operated. When enabled, the switching module alternates the motor on each call from G/P1
input and also switches motors in the event of:
•Current overload of a motor
•Motor set to standby
•Lack of water on subsequent automatic reset
