Placement of the switchgear and installation of connections

The INSTAL-BLOK switchgears are designed for indoors installation. They can be placed directly on concrete flooring of the facility. Regardless of the type of foundation, switchgears must be placed exactly horizontally (maximum deviation may not exceed 2 mm over 1 m of base length). The switchgear (single cell) should be fixed to the foundation with 4 M8 bolts in locations shown on Fig. 1. When placing the switchgear appropriate spacing should be maintained between the switchgear and other elements in the room in accordance with the regulations in force.

External connections are made as:

  • cables from the bottom to the supply bay and outgoing bays from a cable duct,
  • busbars or cables from the top to the supply bay,
  • cable from the top to outgoing bays.

Note:
Duct depth should be adapted to the number and cross-section of the cables.
