2.2 Installation

Only install this appliance in dry locations.
To function correctly, please note that the
appliance must not be exposed to strong
electromagnetic fields. Ensure that the
controller can be separated from the mains
supply by an additional isolator, which can
separate all poles with at least 3 mm contact
separation, or with an isolating facility in
accordance with current regulations. When
installing the power cable and the sensor
leads, ensure that they are routed separately.

casing.
2. Mark the support on the base and pre-fit
the rawl plug supplied with the appropriate
screw.
