ELECTRICAL CONNECTIONS

Attention! Always and only work on the electrical connections when the machine is switched off. The instrument

is equipped with a screw terminal block for connecting electrical cables with a max. cross-section of 2.5 mm2

(only one conductor per terminal for power connections): the capacity of the terminals is indicated on the label

of the instrument. The relay outputs have no voltage. Do not exceed the maximum permissible current; in case

of higher loads, use a contactor with the appropriate rating. Ensure that the power supply voltage corresponds to

the voltage required by the instrument.

The sensor is not characterised by any connection polarity and can be extended using a normal bipolar cable

(please note that the extension of the sensors affects the electromagnetic compatibility (EMC) behaviour of the

instrument: wiring must be carried out with care). It is advisable to keep the probe cables, power cables and the

TTL serial port cable separate from the power cables.

PERMITTED USE

In the interests of safety, the instrument must be installed and operated in accordance with the instructions

supplied and, in particular, parts with dangerous voltages must not be accessible under normal conditions. The

device must be adequately protected from water and dust depending on its application and be accessible only

with the use of a tool (with the exception of the front panel).

The device is suitable for domestic and/or similar refrigeration equipment and has been tested for safety in

accordance with harmonised European reference standards. The device is classified:

• based on its construction, such as an electronic automatic control device for incorporation;

• based on its automatic operating characteristics, as a Type 1 B action control device;

• as a class A device with respect to the class and structure of its software.

UNPERMITTED USE

Any use other than that permitted is strictly prohibited. It should be noted that the relay contacts supplied are

functional and subject to wear: the protective devices provided for by the product standards or suggested by

common sense, in accordance with specific safety requirements, must be installed outside the instrument.
