The FMP mounting plate comes pre-fitted with a CBX junction box. Depending on the specific variant of the FMP, a CBR lighting control box, with or without a power strip, may also be pre-installed and connected.

The FMP is typically mounted on the HTK diffuser box and is used to simplify the connection of an active diffuser where lighting control or another control box needs to be added.
The FMP can also be ordered with pre-installed Wago connectors.
