Installation and operation
The following must be observed when performing electrical work on the regulator:
Depending on the version, the regulator is designed for use with 115V or 230V (±15 %) alternating
voltage with a frequency of 50 or 60Hz (see rating plate). Operation with different ratings is not
permitted. Also ensure the permitted current ratings are not exceeded.
If an Earth conductor is intended or required for the pump, the Earth conductor must be connected.
The corresponding Earth conductor wire terminals are provided. Ensure that the ground contact is also
connected to the regulator’s mains supply side. Cables, which are not permanently connected with the
building must be provided with a strain relief outside the regulator.
The regulator may only be used for the intended purposes. No liability shall be assumed for any non-
compliant usage.
Any work with an open regulator may only be carried out if the mains power is disconnected.
All safety regulations for working with the mains apply here. The connection, and any work
where the regulator has to be opened, may only be carried out by trained electricians. The
regulator is protected against overcharging and short circuiting.
2.1
Location of installation
The controller is designed for installation on vertical walls. It must not be installed in areas where you
can find flammable liquids or gases. It is only allowed to install the controller in areas in which the
protective system (see Technical data) is sufficient.
The max. permissible ambient temperature at the place of installation must never be exceeded or
fallen below. Moreover, the controller must not be used in moist rooms (bathrooms) or in rooms in
which flammable gas mixtures (by gas bottles, paint, solvents etc.) are likely to occur!

Installation
Wall mounting
The upper regulator cover (fig.1, no. 1) protects the regulator’s electronics and may not be removed
for installation purposes.
Screw 1 must first be screwed into the wall to mount the regulator. The regulator is subsequently hung
on this screw with the cutout (fig.1, no. 2). The regulator can be used as a template to mark the two
other mounting holes (fig.1, pos. 3 and 4).
(Warning: only use the regulator as a marking template, never as a drilling template).
After tightening the controller to the wall, you can start with the wiring.
