Standard PQFS enclosures have dimensions of 588 x 326 x 795 mm (width x depth x
height). Each enclosure contains one power unit and is fitted with its own main
contactor. Power cables with protecting fuses can be connected to each PQFS from the
bottom.
A spacing of 30 mm between the filter sides and walls or other enclosures is
recommended. However the filter can rest on its back against a wall.
A spacing of 500 mm below the filter bottom and above the filter top is recommended.
Figure 18 shows a view of a typical PQFS with characteristic dimensions.
