2.1. Mounting Requirements
ƒ Mounted vertically on a flat surface.
ƒ A clearance of at least 50 mm on all sides of the unit to allow for adequate
ventilation. The grilles must NOT be obstructed.
ƒ Sufficient clearance must be left to allow for the connection of cables and trunking.
ƒ The ambient temperature must be within the range of 0ºC to 40ºC and the area
must be adequately ventilated.
ƒ Humidity must be within the range of 0% to 90% (non-condensing). Do NOT install
this product in a damp location.
2.2. Mounting Procedure
Use 4 screws (not provided) to mount to
the wall (No.8 or No. 10 screws with a head
diameter greater than 6 mm and less than
9 mm).
Note 1 Use the mounting holes located
at the furthest corners of the
chassis.
Note 2: If you are replacing an Imagine
dimmer, e.g.HES99400, and are
using the existing screw
locations, then you can use the
two holes at the top and the two
in the middle.
Note 3: Use wall plugs, if necessary.
