Protective earthing (grounding) inside the compact skid

The protective earth (PE) terminals or frames of the main components in the compact skid
are connected to two main PE terminals located at the corner of the building.

At the installation site:

•

measure the continuity of all internal PE connections by measuring the conductivity
between each protective earth terminal and the main PE busbars

•

earth the shields, armors and protective conductors of all incoming cables to the
appropriate earthing terminals of the station.

For more information, see drawing 3AES-PVS980-CS-02-DW02

Measuring the insulation resistance of the cabling

Make sure that the insulation resistance of the external power cables are measured according
to manufacturer recommendations and local regulations.

Connecting DC cable from solar generator to inverters

WARNING!

Make sure that the cable entry is sealed to maintain the IP classification of the
inverter.

See also,

PVS980 hardware manual

(

3AXD50000026013

[EN]) and the wiring diagrams

delivered with the compact skid.

To connect the DC cable from solar generator to inverters:

1.

Remove the covers of the cable entries.

2.

Lead the cables into the compact skid and seal the entry with the gland plates that is
delivered with the inverter.

3.

Connect the cables to correct terminals of the inverters. Tighten the connections to the
torque values given in the

PVS980 commissioning and maintenance manual

(

3AXD50000046782

[EN]).

4.

Fill the cable trenches and seal the cable entries. See Finalizing the installation. to do:
link to correct section.

Connecting the communication and auxiliary cabling
(Optional)

See the following drawings:

•

Auxiliary service board drawing—3AES-PVS980-CS-14-SP01

•

Communication cabinet drawing—3AES-PVS980-CS-15-SL01

•

UPS connection drawing—3AES-PVS980-CS-16-SP01.

To connect the cabling for auxiliary cabinet, communication and UPS:

1.

Remove the cable entry covers.

2.

Lead the cables into the station and seal the cable entries.

3.

Connect the cables to the correct terminal in the AC cabinet (communication cabinet
and AC distribution cabinet). Tighten the connections.
