Mounting Location
To ensure convenience of use, the RWB30 should be fitted in a position
which allows easy access. It is recommended that the unit is placed at
a height of 1.4 metres from the floor.
NB
The RWB30 should not be installed in locations that are directly
exposed to water splashes or steam from cooking utensils and
kettles etc.
Backplate
The RWB30 is supplied with the industry standard backplate to which
the system must be wired. The backplate can be fitted directly to the
wall or it may be wired on a standard conduit box. If it is fitted to a wall,
do not mount on an unearthed metal or metallic surface. If a conduit
box is fitted all wiring to the backplate should pass through the base.
The backplate is the same as that used with: RWB3, RWB30, RWB50,
RWB100 series and RWBXT Timeswitches.
When the RWB30 is used as a direct replacement no re-wiring is
necessary, (except in the case of the RWB3 when
a link should be
inserted across Terminals L and 2 as shown in Fig. 2).

The voltage applied to terminal 2, is switched to terminal 4 when the
timeswitch is in the ON position and to terminal 3 when the
timeswitch is in the OFF position (see Fig. 2). If 240V direct mains
switching is required link terminals L to 2.
Note:
All external wiring must comply with current IEE regulations.
Wiring of this unit should be carried out by a qualified electrician.
Whilst every effort is made to ensure the accuracy of the instructions
given, you will appreciate that the discrepancies may occur due to a
variety of reasons outside our control. If after wiring your system you
find that it does not work properly you should:
Check that you have used the correct system and wired it correctly.
Ensure that no wiring unit links have been missed and all screws are
tight.
Check with the Technical Help line, there may be a simple explanation.
(Technical Help Line: 01952 602048 Mon - Fri 9am - 5pm).
N.B. These units are not suitable for control of immersion
heaters.
Fitting the Unit to the Backplate
Tilt the bottom of the case away from the wall, locate the two slots in
the top of the case, over the two tabs at the top of the backplate. Push
the bottom of the case towards the wall, slotting the two backplate
screws into the bottom of the case, and tighten the screws. This
enables the contacts in the unit to engage with those in the backplate.

It is a good wiring practice that
the supply to the unit should be
via a two pole disconnection
providing at least 3mm air gap.
Please note:
only insert link as above
in Fig. 2 for boilers with 240V
AC.
Be warned:
most combination boilers use
24V so do
not
insert the link
for these applications.
