Contents of this chapter

This chapter describes the mechanical installation of the PVS-100/120 medium voltage
compact skid (MVCS) and gives instructions on how to select the location and guidelines
to build the foundation for the MVCS. Always obey the local regulations.

Safety

See Safety instructions (page 9).

Before you move the MVCS, see instructions in chapter Storing, lifting and

transporting (page 29).

Tools

Use the following tools to move the MVCS, to fasten the MVCS foundation, and to tighten
the connections:

• Crane, forklift, or pallet truck (with sufficient load capacity)

• Pozidriv and Torx (2.5 to 6 mm) screwdrivers with short and long heads or bits

• Torque wrench

• Set of wrenches and sockets.

Foundation guidelines

For information on the MVCS dimensions and footprint, see drawing
3AES-PVS-100_120-MVCS-30-DW02.

Always follow the local rules and laws when designing and constructing the foundation. Pay
attention to the proper planning and constructing of the foundation. For example, an improper
foundation can cause settling of the MVCS or difficulty opening the door.

38 Mechanical installation

Follow the below guidelines:

• To prevent any risk of corrosion, install the MVCS higher than its surroundings so that
surface water will not collect around its perimeter.

• Tilt the surface of the surrounding ground at least 50 mm per meter (two inches per 40
in). This ensures that surface water flows away from the MVCS.

• Consider local conditions, such as soil type, frost protection, rain amounts, etc. There
needs to be at least 300 + 200 mm gravel under the foundation.

• Consider the required cable bending radius and installation room.

• The built-on site user platform around the MVCS must be at least one meter (40 in)
wide. If it is narrower, service work can be difficult.

• The entire perimeter of the MVCS must rest on the foundation.

• Check the load carrying capacity of the ground and potential local special requirements
(for example, earthquake or typhoon anchoring) of the construction area. Use materials
suitable for the local conditions and requirements.

Placing the MVCS on the foundation

WARNING!

Before lifting the MVCS onto the foundation, make sure the foundation is aligned
well, hardened and stable.

1. Measure the level of the foundation and the tilting of the surface of the surrounding
ground around the foundation. Obey the Foundation guidelines (page 37).

2. Make sure the foundation below the MVCS is leveled. Inclination up to 0.1 degrees is
permitted.

3.

Lift the MVCS onto the foundation. Obey the instructions in section Lifting (page 31).
Make sure that the foundation does not move. Also make sure that the station is stable
and in direct contact with the foundation.

4. When the MVCS is placed on the foundation, measure the height and inclination of the
MVCS. Check the slope of the surface of the surrounding ground around the MVCS.

Mechanical installation 39

Fastening the MVCS

WARNING!

Do not fasten the MVCS by electric welding, because the welding circuit can
damage electronic circuits and integrity of the station. ABB does not assume any
liability for damages caused by electric welding.

To fasten the MVCS to the foundation, bolt the cabinet through the holes on the base of the
inverter or use the supplied attachment brackets (see figure below). Use bolts and washers
in each connection point.

Attachment bracket

Fastening points

Follow the local regulations and applicable standard to calculate the mechanical connections
and structural properties. Always consider the site conditions and terrain characteristics.

For more information, see drawing 3AES-PVS-100/120-MVCS-30-DW02.

Placement of bracket

Constructing earthing electrode and earthing

Construct an earthing electrode for the MVCS according to the local regulations. For more
information, see drawing 3AES-PVS-100/120-MVCS-02-DW02.

40 Mechanical installation

Filling the pit and finalizing the surroundings

1. If required for local frost conditions, add insulation around the column foundation.

2. To minimize the growth of grass, use geotextile below the foundation and below the
service platform around the MVCS. Put the geotextile 20 cm (8 in) below and about 100
cm (40 in) around the foundation.

3. The MVCS is a not walking station, it is designed to be operated from the outside.
Provide a permanent or portable platform for comfortable operation of the MVCS
switching devices as the foundation can be higher than the surrounding ground. For
platform design and construction, follow the local rules and standards.

4. Do not plant trees near the MVCS. If bushes are planted, make sure that the planting
compost base is at least one meter (40 in) away from the station housing and that the
fully-grown bushes do not prevent maintenance access to the MVCS. Make sure that
anything planted near the inverter does not discharge dust or seeds that can affect the
cooling air flow.
