IMPORTANT NOTE
If the timeswitch to be replaced is listed below it may be worth
considering a FP715 Si as an alternative to the FP975. The FP715 Si
off ers wallplate compatibility for those models listed below, although
some re-wiring may be required.
If the new unit is replacing an existing time control having an
incompatible wiring confi guration, then the wiring conversions
(tables A and B, pages 12-15) will be of assistance.
4. For wiring connections please refer to diagrams on pages 9-10.
Please note, the FP975 does not require an earth connection,
although a terminal is provided for earth continuity purposes.
5. Ensure that the two retaining screws on the top of the timeswitch
are fully unscrewed. Locate the retaining lugs on the bottom
inside surface of the plug-in module under the wallplate base and
hinge the unit upwards until the module is pressed fully against
the top of the wallplate. Tighten the two screws on the top of the
module to secure the module to the wallplate.

bottom fi xing screw.
