Mounting on a surface using sliding brackets
To fasten a VDO Fatron fixture to a surface using sliding brackets:
1. Pass a grade 8.8 strength M12 bolt through the hole in each sliding bracket and use the bolt to fasten the
fixture to the surface.
2. Secure the bolt with a washer and self-locking nut.
3. If you are installing the fixture in a location where it may cause injury or damage if it falls, secure the
fixture with a safety cable as described in “Safety cable attachment” on page 15.
Mounting a column of fixtures joined end-to-end
Warning!
Do not use end-to-end couplers to support the weight of fixtures. Each 1000 mm fixture must have
its weight supported by two sliding brackets or two half-coupler rigging clamps. Each 320 mm
fixture must have its weight supported by one sliding bracket or half-coupler rigging clamp.
You can install a vertical column of VDO Fatron fixtures. The column must be mounted on a vertical
structure or surface using sliding brackets or half-coupler clamps. Fixtures can be aligned using end-to-end
couplers, but each fixture must have its weight supported by sliding brackets or half-coupler clamps.
1000 mm and 320 mm fixtures
To mount a vertical column of VDO Fatron
fixtures:
1. See Figure 11. You will need one
end-to-end coupler each time you join two
fixtures together and two sliding brackets
for each 1000 mm fixture or one sliding
bracket for each 320 mm fixture.
2. Install the sliding brackets or half-coupler
clamps on the fixtures using M6 bolts,
washers and nuts (see “Sliding brackets”
on page 15 or “Low-profile half-coupler
rigging clamps” on page 16). Tighten nuts
to a torque of 8 Nm.
3. Install the top fixture on the surface or
structure, fastening it securely using M12
fasteners passed through the sliding
brackets.
4. If the fixture will cause injury or damage if it
falls, secure it with a safety cable as
described in “Safety cable attachment” on
page 15.
5. Continue installing fixtures as shown in
Figure 11. Secure each fixture with a safety
cable. Use an end-to-end coupler
C
each
time you join two fixtures together (see
“Joining fixtures end-to-end” on page 19).
Fasten the end-to-end couplers
C
to fixtures using M6 bolts and self-locking nuts. Tighten all four nuts
on each coupler to a torque of 6 Nm.
