Installation/configuration notes
The cabinet is designed for both surface and recessed
mounting on walls. The back box provides a selection
of mounting holes, even for mounting on U40 and MK
installation boxes. The back box has two knockout
holes on the topside for two cable glands (not
included) for loop-through connection. For extra
installation convenience, a safety cord from the back
box lets the installer temporarily hang the front grille
unit during installation.
The cabinet has a three-way terminal block with screw
connections suitable for loop-through wiring (including
earth).
Four primary taps on the matching transformer allow
selection of nominal full-power, half-power, quarter-
power or eighth power radiation (in 3 dB steps).
