Mains installation

This product must be installed by a quail­fied person in accordance with I.E.E. wiring
regulations. The examples are suitable for
connecting to a mains input / mains output
installation.

Volt-free switching

If there is no link between terminals 3 and
5, it is possible to use the timer to control
a load on a separate supply circuit, which
can be a different voltage value up to 250 V
AC. In this case, connect the mains live and
neutral to 5 and 4 respectively, then con­nect the live in / live out of the circuit to be
switched, to terminals 2 and 3.

Installation procedure

1. Switch off supply to socket box.

2. Unscrew the two screws located top left
and bottom right of the front module
cover; remove cover and gently pull
module from backplate. Do not put
undue stress on, or interfere with fixed
blue wires.

3. Fix backplate to socket box.

4. Connect wiring in accordance with
wiring diagram. Do not combine solid
and flexible conductors in the same
terminal. When connecting flexible con­ ductors use the ferrules supplied.

5. Fit cover over module and reassemble to
backplate. Ensure fixed blue wires
stowed neatly without being trapped.

6. Re-fit and tighten two screws.
