INSTALLER WARNINGS
-
Install the appliance in places that respect the degree of protection and keep the box as
intact as possible when drilling for the housing of the cable glands and/or pipe glands.
-
Avoid using multi-pole cables in which conductors connected to inductive and power
loads and signal conductors are present, such as probes and digital inputs.
- Avoid housing power cables with signal cables (probes and digital inputs) in the same
ducts.
- Reduce the lengths of the connection cables as much as possible, avoiding that the
wiring takes on the shape of a spiral capable of possible inductive effects on the
electronics.
- All conductors used in the wiring must be suitably proportionate to support the load they
must supply.
- If it is necessary to move the probes farther, it is obligatory to use conductors of
appropriate cross-section and in any case not less than 1 mm
2
. Extending or shortening
of the probes could alter the factory calibration; then proceed with verification and
calibration by means of direct comparison with a thermometer that is ACCREDIA tested
and certified.
