Surface Mounting
The EMU11/17 without bezel can be surface
mounted using the 4 securing holes as shown
in figure 5. The unit can be stood off from the
mounting surface by 10mm using the 4 spacers
if required. Screws are not provided and it
must be remembered that if used in this way
the EMU11/17 must be installed within a
housing or cubicle to prevent access to the
mains terminations.
Installation - Panel Mounting
For panel mounting (in panels up to 7.0mm thick
with the cut-out as shown in figure 2) the
EMU11/17 should be snapped into the bezel
supplied and secured in place by the use of the 2
No. 6 x 3/8in self-tapping screws provided as
shown in figure 3.
When selecting a position for the unit it should be
born in mind that a clearance behind the front
panel surface of 26.0mm is required over the full
area of the panel cut-out.
The unit is designed to be mounted from the front
of the panel by the following procedure:
a. Insert the 2 bolts provided in the locations
shown in figure 4.
b. Then insert the 2 No. 4 x 5/8 in self-tapping
screws into the bolts and engage thread.
c. Make connections to the unit by wires
terminated in a Molex 4 way 7720 or similar
connector from behind the panel.
d. Insert the EMU11/17 complete with bezel into
the panel and tighten up the 2 No. 4 selftapping screws. The ears on the bolts will
Bolt
rotate under the tightening action to clamp the
unit to the panel.

Operation
The programme button advances programme steps and the change
button the hours and minutes which flash. Time of day is set first
and is updated during the programming period. Programmes 1 to 4
follow. If, during programming, no button is pressed over a period
of one minute then the display will revert to normal operation. In
normal operation, pressing the change button changes the output
until the next programme step.
