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
section (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 outputs, 2 x 2.5mm
for each individual contact to ensure the temperature of the cables does not exceed 85°C.
• Fastons: double 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.
