|Dimensions:||L 160mm W 120mm D 71mm|
|Construction:||Electronic power supply resin-potted into a black polycarbonate box|
|Input Voltage:||240v input|
|Watts:||35 watts. Will power a maximum of 115 Navigator Aqua, 70 Navigator Minor , 35 Navigator Major or 17 Navigator Maxor/Navigator Eye fittings|
|Installation:||For surface mounting: Using a slotted screwdriver, rotate each of the 4 quarter-turn corner fixings 90 degrees to the "0" position and remove the lid to reveal the fixing slots in each corner. Secure the transformer to a wall or post with 5mm screws in each corner, or attach to optional transformer mounting stakes. Install the transformer on a wall or post approx. 30cm above ground.
For ground burial: Make all connections in T9969 underground joint kit or similar resin-sealed joint. (Boxes with silicon-sealed lids do not protect against ingress of moisture through condensation and capillary action: ordinary silicon sealant does not bond reliably with all enclosure materials.) After burying the transformer and associated junction boxes, lay a paving slab or similar protective material over it, cover with cable warning tape and back-fill hole. NB: Where multiple ground burial transformers are to be installed in an area, allow connection points where possible above ground to allow for isolation in the event of future fault-finding. Connection of transformers to separate cores of a multicore cable may also be considered. Failure to adopt these recommendations may mean difficulty in fault diagnosis in the future and in extending or upgrading the system.
