• Please note the IP (Ingress Protection) rating of this product when deciding the location
for installation
• Do not overload this accessory or subject it to conditions outside its rating
• This product is Class I and must be earthed
• This product is IP66 rated

INSTALLATION
Please note: the unit should be fixed to a rigid flat surface as unevenness could cause
damage to the product or affect operation
• Provide power to the required point of installation (refer to BS7671 for correct cabling
methods)
• Remove the front assembly from the backbox and carefully lift off the gasket. Drill the
required number of fixing holes in the backbox (see Fig. 1)
• Using the backbox as a template, mark the location for, and drill the fixing holes ensuring
not to infringe with any gas/water pipes or electrical cables. The backbox can be rotated
through 180°if required, to position the two cable entries on the top

•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

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

•Remove one or more of the pre-fitted blank plugs as required by pushing out from the inside and install
a suitable IP rated gland or adaptor (not supplied). For rear entry, cut or drill a 20/25mm hole where
marked and install a suitable IP rated grommet (not supplied). Unused cable entries must have the
blank plugs fitted
•Feed the mains cable into the unit and secure the base plate to the surface. The fixing holes are
slotted to allow some rotational adjustment
•Replace the gasket onto the backbox, then wire as shown in Fig. 3 ensuring that correct polarity is
observed: L - Live (brown), E - Earth (green/yellow), N - Neutral (blue)
Fig. 3 OP7N OP9N
•An earth connection must be made to the earth terminal of the socket. Use green/yellow sleeving on
earth conductors that are not insulated. The earth terminal in the backbox is provided for convenience
and does not need to be connected
•Check all electrical connections are secure with no loose strands of cable
•Ensuring the gasket does not become damaged or pinched, fit the socket assembly onto the backbox,
taking care not to compress, damage or trap any cables, and secure with the screws provided - do not
overtighten
•Fit screw covers
•Switch on and check for correct operation
For security, and to prevent unwanted tampering with the product, a lug feature with a 6mm hole is provided to
accept a padlock or similar locking security device (see Fig. 4).
