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 liquids�
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 and/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�
Voltage spikes on the connections of the device are to be limited to the values of
overvoltage category II�
