The instruments are provided with screw terminal block to connect cables with a cross section up to 2.5mm
for the digital and analogue inputs. Relays and power supply have a Faston connection (6.3mm). Heat-
resistant cables have to be used. Before connecting cables make sure the power supply complies with the
instrument's requirements. Separate the probe cables from the power supply cables, from the outputs and
the power connections. Do not exceed the maximum current allowed on each relay, in case of heavier loads
use a suitable external relay.
N.B. Maximum current allowed for all the loads is 20A.
14.1 PROBE CONNECTIONS
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is
recommended to place the thermostat probe away from air streams to correctly measure the average room
temperature.
