Connecting Signal Source to Digital Input GSI

Qualified person

Network cable and fast-stop switch use the same cable gland

If a fast-stop switch is to be connected, plug the network cables into the cable support sleeve along with the fast-stop switch connection cable and insert them into the inverter.

Additionally required material (not included in the scope of delivery):

  • 1 fast-stop switch (break contact)

Requirements:

  • The signal source must be technically suitable for connection to the digital inputs Technical Data.

Procedure:

  1. Disconnect the inverter from all voltage sources .
  2. Remove the filler plug from the enclosure opening for connecting the network cables.
  3. Insert the M32x1.5 cable gland with four-hole cable support sleeve for communication connections into the enclosure opening for connection to the multifunction relay and the switch for secure power supply operation and tighten it from the inside with the counter nut.
  4. Unscrew the union nut from the cable gland and lead the cable through.
  5. Remove the four-hole cable support sleeve from the cable gland.
  6. Insert the cable into a fitting enclosure opening of the four-hole cable support sleeve. In doing so, pierce the closed side of the enclosure opening.
  7. Press the four-hole cable support sleeve with the cable into the cable gland and route the cable to the GSI slot on the communication assembly.
  8. Dismantle the cable by 20 mm.
  9. Strip off the conductor insulation by 6 mm.

  14. Plug the 2-pole connector with connection cables into the socket GSI on the communication assembly. Observe the pin assignment.
  15. Ensure that the connector is securely in place.
  16. Ensure that all conductors are correctly connected.
  17. Ensure that the conductors sit securely in the terminal points.
  18. Tighten the swivel nut on the cable gland hand-tight.
