The backbox has drain hole drilling guides marked (see Fig. 2). Drilling a drain hole is advised if the
unit is installed in a location subject to temperature fluctuations where build-up of condensation may
occur. It is not advised if the unit will be subject to high pressure jets, as drilling a drain hole will reduce
the IP rating. A 3-5mm hole should be drilled at the bottom back edge of the enclosure where marked.
If wiring in conduit to the bottom entry, then the drain hole should be drilled at the lowest point of the
conduit run not in the backbox
