Switchgear setting and termiinal assembly

INSTAL-BLOK switchgears are designed for indoor installation. They can be set directly on the concrete ground of the facility. Regardless of the flooring, switchgears must be placed horizontally (maximum deviation in surface profile shall be 2mm over a 1 m gauge length). The switchgear (a single cell) should be fixed to the ground with four M8 bolts as shown in Figure 1. During switchgear installation, particular attention should be paid to save enough space between the switchgear and other facility elements according to applicable regulations.

External terminals are made as:

cables from the bottom side of the power supply bay and receiving bays from the cable duct
busbars or cables from the top side of the power supply bay
cables from the top side of the receiving bays
