16 VDO Fatron™ Family Safety and Installation Guide
To install brackets on a VDO Fatron 1000 mm
fixture:
1. Place the fixture with the LEDs facing
downwards on a surface that will not scratch or
damage the fixture.
2. Make sure that you know which brackets and
couplers are required. You must install these in
the correct order.
3. See Figure 5. Loosen both the self-locking
nuts G on a sliding bracket.
4. Pass the bolt heads I through the cutout and
into the channel in the rear of the fixture (see
Figure 3 on page 15) and slide the bracket to
its correct position, then tighten the nuts
G to a torque of 8 Nm.
Note that washers H must be installed under the nuts G at all times.
Low-profile half-coupler rigging clamps
You can bolt half-coupler rigging clamps available from Martin® (see “Accessories” on page 47) to sliding
brackets for the VDO Fatron and then use the clamps to fasten the VDO Fatron to a rigging truss or similar
mounting bar.
If you prefer, and if space allows, you can fasten the Low-Profile
Rigging Clamps available from Martin® directly to the VDO
Fatron without using sliding brackets.
Low-Profile Half Coupler Clamps must be installed in place of
the sliding brackets shown at
E in Figure 2 on page 13:
• Each 1000 mm fixture must be supported by at least two
clamps located at each end of the fixture, close to the fixture’s
cable tails.
• Each 320 mm fixture must be supported by at least one clamp
located in the center of the fixture.
• Each fixture that is installed in a location where it may cause
injury or damage if it falls must also be secured by a safety
cable located in the center of the fixture.
To fasten VDO Fatron fixtures to a surface or structure using
half-coupler clamps:
1. Loosen, but do not remove, the nut on each half-coupler
clamp.
2. See Figure 6. Slide the nut on each clamp through the cutout
and into the channel in the back of the fixture.
3. Slide the clamp to its correct position, then tighten the clamp screw (arrowed).
