ELECTRICAL CONNECTIONS

Important! Make sure the machine is switched off before working on the electrical connections. The instru-
ment is equipped with screw-on terminal boards for connection of electrical cables with a diameter of 2.5 mm
(one conductor only per terminal for power connections): for the capacity of the terminals, see the label on the
instrument. The relay outputs are voltage free. Do not exceed the maximum permitted current; for higher loads, use
a contactor with sufficient power capacity.
Make sure that power supply is of the correct voltage for the instrument. NTC probes have no connection polar-
ity and can be extended using a normal bipolar cable (note that if the probes are extended this influences the
device's electromagnetic compatibility - EMC: take great care with the wiring). Probe cables, power supply cables
and serial cables should be routed separately from power cables. The pressure/ratiometric probe has a connection
polarity which must be observed.
