Installation
All electrical installation and maintenance must be carried out by a competent person. If in doubt,
consult a qualified electrician. Any new wiring must be carried out by qualified personnel in
accordance with the current edition of the IET Wiring Regulations (BS7671).
!
Ensure the electrical supply is isolated before making any connections or adjustments.
!
1. Prepare a single-gang pattress or back box as necessary.
2. Rotate the
Timeout
thumbwheel (referring to the accompanying label) to set the period
of time for which the load should remain switched on after a contact closure trigger.
3. Connect the wiring as shown in Figure 2 (or in any suitably appropriate form).
−
Supply connections (L, N):
Use appropriate mains cable to power the unit. If the
load is also powered via this wiring, ensure the current rating is adequate. Otherwise
(i.e. if the output is independently powered), low-current cable may be used.
−
Load connections (LIVE IN, LIVE OUT):
Use cable rated for the load current and
voltage.
−
Remote input connections (V+, R+, R-):
Low-current cable may be used but
must
be rated for mains voltages
. Refer to
Remote Input Wiring
for wiring details for
different input devices.
4. Fix the unit into position with the two screws and caps supplied.
Additional Guidelines
•
The screw caps may be removed at a later date with the aid of an adhesive putty such
