3.1 Installation notes

a
The choice of cable, the installation, the fusing and the electrical connection must conform to the requirements of VDE
0100 "Regulations on the Installation of Power Circuits with Nominal Voltages below 1000 V" or the appropriate local
regulations.
a
The electrical connection must only be carried out by qualified personnel.
a
Electromagnetic compatibility conforms to the standards and regulations cited in the technical data.
v
Chapter 7 "Technical data"
a
The instrument is not suitable for installation in areas with an explosion hazard. It must be built into a housing that
provides protection against fire and electrical hazards.
a
Apart from faulty installation, incorrect settings on the instrument may also affect the proper functioning of the
subsequent process or lead to damage. Safety devices should always be provided that are independent of the
instrument (such as overpressure valves or temperature monitors/limiters) and only capable of adjustment by specialist
personnel (lock the parameters for operation). Please observe the relevant safety regulations for such matters.
a
The load circuit must be fused for the maximum relay current, in order to prevent the output relay contacts becoming
welded in the event of a short circuit there.
a
Do not connect any additional loads to the screw terminals for the supply of the instrument.
a
The external fusing of the supply should not be below 1A, depending on the conductor cross-section.

3.2 Correct positioning of the probes

a
The probe for the temperature of the cold store should be positioned in the air stream of the fan, in a place where the
average temperature of the refrigerated goods can be acquired (not too close to the evaporator, and also not right at the
bottom of the cold-storage room).
a
Place the probe for the evaporator temperature there where it will be iced up longest !
