• The devices are designed for wall-mounting (A). A conduit box is optional.
Conduit box: Keep in mind the dimensions of the conduit box!
−
Cable conduits on the wall: Keep a distance of 30 mm (from above) /
−
20 mm (from below) to the base plate (B), so that the device (C) can be
snapped onto the base plate.
• The base plate (B) has screw holes for all common flush-mount boxes.
The screw head height must not exceed 3 mm.
• The device (C) incorporates a KNX / PL-Link plug, a tool plug, and, depending
on the type, sensor element, keys, LCD panel, window for the label.
The cable can be pushed into channels on the rear.
• A KNX plug is enclosed with the devices
The optional metal-reinforced base plate QMX3.MP1 (B1) serves for two purposes:
• It is more rigid so that it does not bend when fixed in the middle with two screws
only (directly over a conduit box or a cavity wall box).
• It has a removable gray foam plate (B2) for mounting on a 68 mm diameter
cavity wall box. The plate compensates for the jutting edge of the box (see
mounting, page 5).
QMX3.MP1 is supplied in boxes with 20 pcs.
