1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). To be fitted to a panel, screwed-in brackets provided.
INSTALLATION PRECAUTIONS
- the thickness of the panel must be between 0.8 and 5.0 mm (1/32 and 1/16 in)
- the maximum clamping torque applicable to the screwed-in brackets is 10 cNm
- 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
- ensure that the thermocouple is properly insulated from contact with metal parts or
use already insulated thermocouples
- if necessary, extend the thermocouple cables using compensating cables
- where they are two multi-purpose inputs, multi-purpose input 1 has priority over
multi-purpose input 2
- the TTL MODBUS port can be used as an alternative to the USB port and vice versa
- 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.
