2. Installation
The unit is suitable for connection to a 230 V ac 50Hz electricity supply. It is suggested that 2-core round flexible cable of 1mm 2 gauge is used. A switch should be installed to turn the power to the unit ON & OFF. This allows the sensor to be easily switched off when not required or for maintenance purposes.The NSLB90 is a class
2 luminaire and does not need to be earthed.
*** IMPORTANT ***
Switch off the electricity at the fuse box by removing the relevant fuse or switching off the circuit breaker before proceeding with the installation.
We recommend that this unit be fitted by a qualified electrician. Install in accordance to current wiring and building regulations. Please read the instructions carefully.
If in any doubt contact the Timeguard Helpline.
Remove the diffuser using a large flat blade screwdriver to release the clips on both sides (diagram A).
Detach the connection cover by removing the fixing screw
(located above the cable inlets).
Ensure the unit is in an upright position with the sensor module at the bottom. Mark the position of the fitting holes.
Drill the holes. Insert wall plugs into the holes if necessary.
Make an undersize hole in the blind grommet to guard against water ingress and pass the cable through the hole before proceeding.
Use the channel on the rear of the case to route the cable if necessary then fix the case to the wall. Beware of overtightening the screws on an uneven surface as this may distort the case.

4. Operation and Testing
SETTING UP FOR AUTOMATIC OPERATION
The adjustment controls on the underside of the unit
(diagram B) should be set as follows.
The TIME control determines how long the lamp remains illuminated after activation. The minimum time (fully anti-clockwise) is approx. 1 hour, whilst the maximum time
(fully clockwise) is approx. 12 hours. Set the control to the desired setting between these limits.
The DUSK (LUX) control determines the level of darkness required for the unit to start operating.
Wait until the ambient light level reaches the level at which you like the light to turn on. Set the DUSK control knob fully anti-clockwise then move the DUSK control a small step at a time clockwise pausing for some time between steps until the light turns on. Leave the control set at this point.
At this position, the unit should become operative at approximately the same level of darkness each evening.
Observe the operation of the unit. If the unit is starting to operate too early (ie. when it is quite light), adjust the control slightly anti-clockwise. If the unit starts to operate too late
(ie. only when it is very dark), adjust the control slightly clockwise. Continue to adjust until the unit operates as desired.
