WARNINGS
Important! Make sure the machine is switched off before working on the electrical connections.
The instrument is equipped with:
• Removable screw terminals: for connecting electric cables of 2.5 mm
tion (one wire per terminal in the case of power connections): for the capacity of the terminals, see the label
on the instrument. The relay outputs are voltage free: they are indicated on the board with the letters COM for
Common, NO for Normally Open and NC for Normally Closed contact. When current exceeds 8A on relay out-
puts, 2 x 2.5mm
cables (2 fastons) must be run out for each individual contact to ensure the temperature of the
2
cables does not exceed 85°C.
• Fastons: single row of fastons in series. 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.
Probes have no connection polarity and can be extended using a normal bipolar cable (note that the extension
of the probes influences the instrument's electromagnetic compatibility (EMC): take great care with the wiring).
Probe cables, power supply cables and the TTL serial cables should be routed separately from power cables.
