To make this arrangement on the wall, the reference point is the aisle at the front of the
switchgear ( 1500mm or
side of the switchgear (X dimension) determines the length of the outlet channel. It should be
specified during the order stage to be able to provide adequate channel.
NOTE!
Please see on page49 – 54 for the detailed information of the assembly of pressure relief
channels.
8BT2 switchgear complies with the following degrees of protection according to IEC 60529:
• IP4X for switchgear enclosure of the operating front and the side walls
• IP2X for between compartments
Degree of Type of protection
protection
IP4X Protection against solid foreign objects: Protected against solid foreign objects, diameter > 1 mm.
Protection against electric shock: Protected against access to hazardous parts with a wire (the access probe
of 1 mm diameter shall not penetrate).
IP2X Protection against solid foreign objects: Protected against solid foreign objects, diameter > 12.5 mm.
Protection against electric shock: Protected against access to hazardous parts with a finger (the jointed test
finger of 12 mm diameter, 80 mm length, shall have adequate clearance from hazardous parts).

Environmental conditions
To achieve appropriate electromagnetic compatibility (EMC), some basic requirements
must be observed while erecting the switchgear. This applies especially to the
installation and connection of external cables and wires.
Basic measures for ensuring EMC are already taken during design and assembly of the
switchgear panels. Among other things, these measures include:
• the low-voltage compartment is an integral part of the panel, which means that the
protection and control devices with the internal wiring are metal-enclosed;
