Mounting plate
Non-enclosed (IP00) filters must be mounted on a grounded metal plate or cabinet
frame. Enclosed (IP22) filters can be installed to a wall without any grounded metal
plate. The structure must be of non-flammable material and strong enough to carry
the weight of the unit.
￭
Encasing
Non-enclosed (IP00) filters must be encased or placed in a cabinet according to the
local safety requirements.
￭
Electrical connections
• Busbars are recommended for connections to the input terminals of non-enclosed
(IP00) filters.
• Cables are recommended for connections to the input terminals of enclosed (IP22)
filters.
Cables must be protected for at least 105 °C (221 °F). If the filter is not installed in the
same cabinet as the drive, shielded symmetrical cable must be used between the drive
cabinet and the filter enclosure.
￭
Free space
Free space is required around the filter for cooling as follows. The distances apply to
natural convection. With forced cooling, less free space is required.
