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.
