4. Installation
• Ensure that the mains supply to the circuit breaker
is switched off and the circuit supply fuses are
removed or the circuit breaker turned OFF.
• Remove the front panel by unscrewing the four
fixing screws.
• If necessary, carefully remove the printed
circuit board (PCB) by undoing the four PCB
mounting screws.
• Remove the cable knockouts at (preferably)
the bottom of the box.
• Use the appropriate IP65 rated entry conduits
to fit the M20 knockouts. Ensure they are tightly
fitted to maintain the IP rating.
• Mark the position of the fitting holes using the
surface mount box as a template. Drill out the
mounting holes taking care to avoid any joists,
electrical cables or water/gas pipes that may be
hidden beneath the surface. Insert the rawl plugs
into the holes.
• Fix the surface mount box rigidly to a secure
surface by using the appropriate screws through
the four fixing holes.
• If necessary, carefully refit the PCB back into the
surface mount box by progressively tightening
each of the four PCB mounting screws in turn.
Do not over tighten the screws.
• Pass the 230V 50Hz mains supply and load
cables through the cable conduits on the
surface mount box.
• Terminate the cables into the terminal block
ensuring correct polarity is observed and that
all bare conductors are sleeved (See section 5.
Connection Diagram).
• Secure the front panel back into place using the
four fixing screws previously removed.

6. Internal Delay
Selection Switches
• There are four internal DIL switches available to
select 8 time delay settings as shown below;
Note: On the DIL switch, switch 1 is not in use.
• Select your desired time delay period and set the
DIL to the relevant positions using the above chart.
There is a single blue LED illuminated push button
switch on the front panel. When pressed, the DS3HD
will function as follows;
• The blue LED will turn OFF.
• The externally connected load will turn ON
for the pre-selected time delay.
• One minute before the end of the time delay,
the blue LED will flash, indicating the time
delay is due to expire.
• At the end of the time delay, the externally
connected load will switch OFF from the
mains supply.
• The blue LED will switch permanently ON until
the push button is pressed again.
• If the button is pressed while the time delay
is still running, the delay will be terminated
after 1 minute.
• If the push button is pressed within the last minute
of the time delay (when the blue light is flashing)
the countdown will be reset and the timer will
restart the time delay.
