13.3 Cables and plugs

The pump has two electrical connections: the power supply and the
control signal connection.

Power supply connection

The installer plug is both supplied with the pump and available as
an accessory.
Power cable adapters are also available as accessories.

Control signal connection

The control signal cable connection has three conductors: the
signal input, the signal output and the signal reference. Connect the
cable to the control box by a mini superseal plug. The optional
signal cable is available as an accessory. The cable length must not
exceed 3 metres.
