1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). 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.
2 ELECTRICAL CONNECTION
N.B.
- Use cables of an adequate section for the current running through them.
- To reduce any electromagnetic interference connect 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 has been moved from a cold to a warm place, the humidity may have
caused condensation to form inside. Wait about an hour before switching on the pow-
er.
- 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 doing any type of maintenance.
- Do not use the device as safety device.
- For repairs and for further information, contact the EVCO sales network.
3 FIRST-TIME
1. Install following the instructions given in the section MEASUREMENTS AND INSTALLA-
TION.
2. Power up the device as shown in the section ELECTRICAL CONNECTION and an internal
test will be run.
The test normally takes a few seconds, when it is finished the display will switch off.
3. Configure the device as shown in the section Setting configuration parameters.
Recommended configuration parameters for first-time use.

Then check that the remaining settings are appropriate; see the section CONFIGURA-
TION PARAMETERS.
4. Disconnect the device from the mains.
5. Make the electrical connection as shown in the section ELECTRICAL CONNECTION with-
out powering up the device.
7. Power up the device.
4 USER INTERFACE AND MAIN FUNCTIONS
4.1 Switching the device on/off
1. If POF = 1, touch the ON/STAND-BY key for 4 s.
If the device is switched on, the display will show the P5 value ("cabinet temperature" default);
if the display shows an alarm code, see the section ALARMS.
