Regulator Connection
First of all leave open the wire entrances for the
power supply connection and the connecting wires of
the sensors and the pump in the casing box. For this
purpose there are material draws to be cut out (fig.2,
Pos. 1). Each wire entrance needs two vertical cuts
into the wall of the plastic case. For the cutting you
can use cable stripping knife or an electronic side
cutter. The cutting depth should be 2 mm min. from
the plastic case ground. Afterwards the plastic clip
can be taken out by moving it back and forth.
The lines outside the regulator must be strain-
relieved (e.g. with strain relief clamps). Alternatively, the cable inlets can be equipped with a housing-
specific strain relief from the manufacturer. If the regulator must be wired through the back panel of
the housing, there are also cut-outs available for PG screw fittings (fig.1, pos. 5) - PG 9.
The connecting activities as described here are only possible when the terminal box
cover plate of the controller is open. For this purpose clear the power supply net. Stick to
all valid regulations for working on a cleared power supply net. Only connect to the
power supply net when controller case is closed. Moreover, the user has to take care of
the fact that the IP protection is not damaged.
The connection of the individual pumps or valves
depends on the layout plan. Therefore in chapter 4, a
corresponding terminal connection table is provided for
each diagram. If a protective Earth wire is provided or
required for pumps or switch valves the Earth wire must
be connected. The corresponding connection terminals
are provided. Ensure the Earth wire is also connected to
the regulator on the mains supply side.
Each terminal may be allocated only one connecting
cable (up to 2.5mm²). Connector sleeves must be used
with finely stranded cables.
