Please read these instructions carefully before starting installation and retain for
future reference.
IMPORTANT SAFETY INFORMATION
NOTE: Before drilling into walls, check that there are no hidden obstructions behind the
mounting surface such as pipes or cables.
•
The timer can be triggered by applying a live connection to the ’TRIGGER’ terminal.
This can be done using a momentary switch in lighting applications for example, or
an unswitched link for applications such as an extractor fan over-run.
•
For switching multiple loads, connect two or more switches in parallel using the
same mains power supply connection.
1. Isolate the mains power to the circuit you are connecting this switch into.
2. Provide a mains supply according to building regulations with reference to IEE
wiring regulations (BS7671).
3. Remove the 4 mounting screws at each corner of the front part of the casing.
4. Mark the position of the 4 mounting holes as indicated on the outer face of the rear
casing (62mm x 92mm centres), drill holes and fit wall plugs as required.
5. Whether you are using cable glands or conduit, you will need to make appropriate
hole(s) in the rear half of the casing to suit your chosen system.
6. Secure the rear casing to the wall using suitable fixings.
7. Feed the wiring in through the glands or conduit connections and connect to the
terminal block on the front part of the switch casing as shown on Figure 1.
● Brown – Live terminal ‘L’ in and ‘L1’ out
● Blue – Neutral terminal ‘N’.
8. Set the desired ‘ON’ time by combination of the DIP switches and rotary control
referring to Figure 2.
INSTALLATION
RISK OF ELECTRICAL SHOCK. ALWAYS ISOLATE THE POWER AT THE MAINS
BEFORE INSTALLING OR MAINTAINING THIS SWITCH.
•
This product must be installed by a competent person in accordance with the
Building Regulations and the current edition of the IET Wiring Regulations
(BS7671).
•
This product is suitable for use with 220-240V~ 50Hz.
•
This product is suitable for indoor and outdoor use..
•
This product is double insulated and does not require connecting to ground.
•
This product will switch incandescent lighting loads of up to 16A maximum,
fluorescent lighting loads up to 6A and compact fluorescent / low energy lighting
loads also low voltage lighting / fans and ventilation equipment loads up to 3A
maximum.
•
If using this product to switch fluorescent lighting, the light fittings must have a high
power factor, or if your light fittings strike inconsistently a power factor correction
capacitor may be required to be fitted.
•
Refer to the lighting manufacturers or power factor correction capacitors literature
to determine the exact specification required for your installation. A minimum of 1µF
for each fitting may be connected. Maximum capacitance not exceeding 40µF .
