Connecting alarm and trip signals from MV substation to
inverter station

Route the alarm and trip signals from the MV substation to the local power enclosure of the
PVS800-IS inverter station as follows:

1.

Dismantle the covers of the cable lead-through holes.

2.

Dig suitable cable trenches and protect the cables according to the local requirements.
Use pipes, ducts, etc.

3.

Lead the cables inside the inverter station through a cable lead-through located in the
bottom of the inverter station next to the exit door. Tighten the cable gland. Make sure
that unused holes and glands will be covered.

4.

Connect the cables to the appropriate terminals in the local power enclosure cabinet.

5.

Fill the cable trenches.

Note:

A ready made PVS800-IS application program template is part of the delivery. The program
can be used as a template for load control functionality during MV substation alarm and trip
situations. Contact your local ABB representative for more information.
