for the digital and analog 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 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 and in case of
heavier loads use a suitable external relay.
N.B. Maximum current allowed for all the loads is 20A.
8.1 PROBE CONNECTIONS
