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

 maximum cross-sec-

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

 cables (2 fastons) must be run out for each individual contact to ensure the temperature of the 

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.
