Unscrew the nut [1] of the cable gland.
→
Remove the terminal block [3] from the housing
[2].
→
Insert the cable through the nut [1] then through
the gasket [4], through the cable gland and
finally through the housing [2].
→
Make the connections to the screw terminal
block [3] (see chap. 7.3.2, 7.3.4, 7.3.6 or 7.3.7).
→
Position the terminal block [3] in steps of 90°
then put it back into the housing [2], pulling
gently on the cable so that the wires do not
clutter the housing.
→
Tighten the nut [1] of the cable gland.

7.3. Wiring
danger
risk of injury due to electrical voltage
• Shut down the electrical power source of all the conductors and
isolate it before carrying out work on the system.
• Observe all applicable accident protection and safety guidelines
for electrical equipment.
• Use shielded cables with a temperature limit of 80 °C
minimum.
• Use a high quality electrical power supply, filtered and
regulated.
• Protect the power supply by means of a 1 A fuse and a
switch.
• Protect the power supply of each transistor by means of a
125 mA fuse.
• Protect the relays by means of a max. 3 A fuse and a
circuit breaker (depending on the process).
• Do not apply both a dangerous voltage and a safety extra-
low voltage to the relays.
