1 MEASUREMENTS AND INSTALLATION
Measurements in mm (inches). To be fitted to a panel, screwed-in brackets provided.
The tolerance of the measurements of the drilling template is +0.2 -0 mm.
INSTALLATION PRECAUTIONS
- the thickness of the panel must be between 0.8 and 5.0 mm (1/32 and 3/16 in)
- the maximum tightening torque applicable to the screwed-in brackets is 10 Nm
- 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 there are three multi-purpose inputs, multi-purpose input 1 has priority over
multi-purpose input 2 and multi-purpose input 3
- 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.
Example of electrical connection with fan modulating with PWM driving signal, with frequency
tracking and with inversion of the fan direction, for EVCO inverter speed regulator (F0 = 4).

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
