INTRODUCTION
These instructions relate to the installation, basic connection and
setting-up of an HES91010 S
CENE
S
ET
Lighting Controller.
For operational instructions, please refer to the User Guide
(part no. I299GB) supplied separately.
INSTALLATION
Choosing a Suitable Location
The HES91010 is designed to be mounted vertically with the connection
points at the bottom; this is to ensure correct ventilation.
The chosen mounting surface must be flat and the location must meet the
following requirements:
·
A clearance of at least 100mm on all sides is recommended to allow
for adequate ventilation.
·
Sufficient clearance must be left below the unit to allow for the
connection of cables, conduits or trunking.
·
The ambient temperature must be within the range 0C to 35C and the
area must be adequately ventilated.
·
Humidity should be within the range of 0 to 90% (non-condensing).
DO NOT install this product in a damp location.
Fixing Method
Mounting is achieved by using the four ‘keyhole’ fixing holes on the side
flanges. The fixing screws (not supplied) must be chosen to suit the
following criteria:
·
Wall Construction
– suitable wall plugs must be used for masonry
construction and plasterboard partitions.
·
Screw Length
– must be sufficient to securely anchor the unit.
·
Screw Head
- round-head, pan-head or cheese-head screws must be
used. The head size should be small enough to just pass through the
large area at the centre of the fixing hole and large enough to clamp
the flange securely in the slotted portion of the hole.
1.
Mark and drill four holes to correspond with the centres of the
fixing holes (see Fig.1-1), and fit wall plugs as required. Note the
drop-down clearance of 12mm.
2.
Insert the screws, and screw them in until the distance between the
wall and the underside if the screw heads is a little more than the
depth of the flange.
3.
Align the centres of the flange fixing holes with the screws, then
allow
the slotted part of the holes to drop-down behind the screw heads.
If necessary, loosen the screws to ease this operation.
4.
Finally, tighten all four screws sufficiently to prevent the unit from
being lifted away.

Cable Access
There are various ‘knock-outs’ on the base of the unit which are suitable
for 15, 20, or 25mm conduit fixings (see Fig.1-2).
These are arranged such that the three left hand positions are used
exclusively for mains cables, whilst the remainder are used for the FELV
(Functional Extra-Low Voltage) control connections.
If required, control cables which are not in conduits can enter the unit via
the slot behind the knock-outs.
