MEASUREMENTS AND INSTALLATION

Measurements in mm (in); 39.5 (1 9/16) depth with fixed screw terminal blocks, 52.5 (2 1/16)

depth with plug-in screw terminal blocks.

To be fitted to a panel, snap-in brackets provided.

INSTALLATION PRECAUTIONS

- the thickness of the panel must be between 0.8 and 2.0 mm (1/32 and 1/16 in).

- ensure that the working conditions are within the limits stated in the TECHNICAL

SPECIFICATIONS section.

- do not install the device close to heat sources, equipment with a strong magnetic field,

in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations

or shocks.

- in compliance with safety regulations, the device must be installed properly to ensure

adequate protection from contact with electrical parts. All protective parts must be

fixed in such a way as to need the aid of a tool to remove them.

ELECTRICAL CONNECTION

N.B.

- use cables of an adequate section for the current running through them.

- ensure that the thermocouple is properly insulated from contact with metal parts or

use an already insulated thermocouple.

- if necessary, extend the thermocouple cable using a compensating cable.

- to reduce any electromagnetic interference locate the power cables as far away as

possible from the signal cables.

PRECAUTIONS FOR ELECTRICAL CONNECTION

- if using an electrical or pneumatic screwdriver, adjust the tightening torque.

- if the device is moved from a cold to a warm place, humidity may cause condensation

to form inside. Wait for about an hour before switching on the power.

- make sure that the supply voltage, electrical frequency and power are within the set

limits. See the section TECHNICAL SPECIFICATIONS.

- disconnect the power supply before carrying out any type of maintenance.

- do not use the device as a safety device.

- for repairs and for further information, contact the EVCO sales network.
