ECM20/ECL60 Installation and Operation Manual
Mechanical Assembly
The instrument is designed for panel mounting. Make a hole of 29x71 mm, insert the instrument and fix it using the brackets provided. Do
not mount the instrument in humid and/or dirty places; it is suitable for use in ordinary polluted places. Ventilate the place in proximity to the
instrument colling slits.
Electrical Wiring
Attention! Never work on electrical connections when the machine is switched on.
The instrument is equipped with screw terminal boards for connection of electrical cables with a diameter of 2.5 mm2 (one conductor only per
terminal for power connections). For the capacity of the terminals, see the label on the instrument. In the model ID 974 with Switching power
supply only one voltage free relay output is present, on all other models on the contrary all relay outputs are voltage free. Do not exceed the
maximum current allowed; in case of higher loads, use an appropriate contactor. Make sure the power supply voltage complies with the one
required by the instrument. In 12V versions the power supply must be provided by a security transformer with the protection of a delayed 250 mA
fuse. Probes have no connection polarity and can be extended using a regular bipolar cable (note that the extension of the probes affects the EMC
electromagnetic compatibility of the instrument: pay extreme attention to wiring). Probe cables, power supply cables and the TTL serial cables
should be distant from power cables.
Conditions of Use
Permitted Use
For safety reasons the instrument must be installed and used according to the instruction provided and in particular, under normal conditions, parts
bearing dangerous voltage levels must not be accessible. The device must be adequately protected from water and dust as per the application and
must also only be accessible via the use of tools (with the exception of the frontlet).
The device is ideally suited for use on household appliances and/or similar refrigeration equipment and has been tested with regard to the aspects
concerning European reference standards on safety. It is classified as follows:
• according to its manufacture: as an automatic electronic control device to be incorporated by independent mounting;
• according to its automatic operating features: as a 1 B-type operated control type;
• as a Class A device in relation to the category and structure of the software.
Unpermitted use
Any other use other than that permitted is de facto prohibited. It should be noted that the relay contacts provided are
of a practical type and therefore subject to fault. Any protection devices required by product standards or dictated by
common sense due to obvious safety reasons should be applied externally.

Liability and Residual Risks
ELIWELL CONTROLS SRL shall not be liable for any damages deriving from:
- installation/use other than that prescribed and, in particular, that which does not comply with safety standards anticipated by regulations and/or
those given herein;
- use on boards which do not guarantee adequate protection against electric shock, water or dust under the conditions of assembly applied;
- use on boards which allow access to dangerous parts without the use of tools;
- tampering with and/or alteration of the products;
- installation/use on boards that do not comply with the standards and regulations in force.
