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 spray
or jets, as drilling a drain hole will reduce the IP rating. A 3-5mm hole can 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
