15.4. Digital input connection process

The digital inputs are connected in the following order:
1. Loosen the corresponding packing gland (see Section "2.7. Description of cable inlets"), remove the cap
and pass the cable through it.
2. Connect the wiring to terminal J54 DIGITAL INPUT as shown in the previous figures, respecting the
polarities printed on the electronic card.
3. Correctly tighten the packing glands to prevent losses to the protection class, verifying that the wiring is
not taut. Check that the connection is tight.
