4 Installation
The device may only be installed and operated in an environment that is in
accordance with the permissible temperature range� Provide sufficient ventilation
and avoid direct contact of the unit with hot or aggressive gases or fluids�
Before installation and maintenance works, the unit must be disconnected from all
voltage sources� Also ensure that contact with disconnected voltage supply wires
is prevented�
Devices that are supplied via AC may only be connected via switches or circuit
breakers to the low voltage supply system� This switch must be positioned close to
the device and clearly marked as disconnecting device�
Ingoing and outgoing cables for extra-low voltage must be separated from
dangerous live cables (SELV circuits) by double or reinforced insulation�
The choice of all cables and their insulation must guarantee that they comply with
the permissible voltage and temperature range� Moreover, both device and country
specific standards are to be observed that apply to the cables with regard to their
structure, shape and quality� Please view the technical data for specifications
concerning permissible wire cross-sections for the screw terminal connections�
Before set-up, all connections and cables must be checked if they are tightly fitted
in the screw terminals� All (even unused) screw terminals must be turned to the
right up to the end stop and thereby reliably attached, so that they cannot get
loose due to shocks and vibration�
