5. Installation
The NTTWIFI is a Wi-Fi controlled time switch which surface mounts.
There is provision for two front cables, with built in cable clamps.
The contacts are not volt free. There is a loop terminal for earth continuity.
5.1 Ensure the mains supply is switched off and the circuit supply
fuses are removed or the circuit breaker turned off.
5.2 Remove the terminal cover by undoing the fixing screw
on the bottom of the time switch.
5.3 Mark the position of the top wall mounting screw. Drill out the
top mounting hole taking care to avoid any joists, electrical cables
or water/gas pipes that may be hidden beneath the surface.
Insert the rawl plug into the hole.
5.4 Fix the top mounting screw and leave 2.5mm proud off of the wall.
5.5 Place the key hole in the top of the product, over the screw head,
and slide down.
5.6 Mark the position of the lower mounting hole on the wall using
the wall plate as a template.
5.7 Remove the product and drill out the lower mounting hole again
taking care to avoid any joists, electrical cables or water/gas pipes
that may be hidden beneath the surface. Insert the rawl plug into
the hole.
5.8 The 230V 50Hz supply and load cables can enter through the
5 6
rear knock outs or the front cable entry ports provided. If the rear
knock outs are being used, remove the blanking plates and pass
the supply and load cables through the holes.
5.9 Place the key hole in the top of the product again, over the screw
head, and slide down.
5.10 Secure the unit to the wall using the lower mounting screw.
If the wiring is through the front cable entry ports, use the cable
clamps provided to secure the supply and load cables.
5.11 Terminate the supply and load cables to the terminal block
ensuring correct polarity is observed and that all bare conductors
are sleeved. Please note the connections are marked beneath
the terminal block (see section 6. Connections).
5.12 Secure the terminal cover back into place using the fixing screw.
