IMPORTANT GENERAL INFORMATION FOR THE INSTALLER
1.
Install the device in places where the protection rating is observed and try not to
damage the box when drilling holes for wire/pipe seats;
2.
Do not use multi-polar cables in which there are wires connected to inductive/power
loads or signaling wires (e.g. probes and digital inputs);
3.
Do not fit power supply wiring and signal wiring (probes and digital inputs) in the same
raceways or ducts;
4.
Minimize the length of connector wires so that the wiring does not have a spiral shape;
5.
All wiring must be of a cross-section suitable for relevant power levels;
6
. Place a general protection fuse upstream from the electronic controller;
7.
When it is necessary to extend the probes, the wires must have a cross-section of at
least 1mm². The probes extension or shortening could alter the factory calibration; then
check and calibrate through an external thermometer.
