4. Surface cables can only enter from below the unit. Cut an
appropriate cable aperture in the wiring cover. If the wallplate is
mounted on a plaster box, cables can enter from the rear below
the terminal block.
5. Electrical connections are simpli ed by using a Wiring Centre.
However, if this is not used, the wallplate terminal identi cation
is as shown.
If the system being controlled is 230 Vac, then terminals 3 and L
must be linked with insulated cable capable of carrying full load
current. Whilst the unit does not require an earth connection,
a terminal is provided on the wallplate for earth continuity
purposes.
6. Refer to the wiring diagrams on page 6-9, connect the unit as
shown.
