3.1.3 Accessories

Footprint brackets
The footprint bracket is an accessory used for mounting
flat-pack brake resistors.
Use the footprint bracket to mount the brake resistor at
the rear of the frequency converter. Once mounted, the
combined brake resistor and frequency converter occupy
the same space in the cabinet as the frequency converter
alone.
