14 VDO Dotron User Manual
Installing directly on a surface
It is also possible to install the VDO Dotron directly on a flat surface if you have access to the back of the
surface.
To install an VDO Dotron on a surface:
1. See Figure 3 (dimensions are in millimeters).
Pre-drill the surface with four holes to accept
mounting screws.
2. Obtain four grade 8.8 (or equivalent strength) M4 x
8 mm machine screws or bolts for fastening into the
back of the dot.
3. Apply a small amount of Loctite to the threads of the
screws or bolts, then pass them through the surface
and fasten them into the back of the dot. Use a
torque driver to tighten to a torque of 2.5 Nm.
4. Connect the dot’s input connector to the output
connector of the previous device on the link, either
directly or via a patch cable. Make sure that all
connectors are correctly fastened together with
locking rings twisted to ensure a seal.
5. Check that the dot is held securely before you leave
it.
Mounting on a rigging truss
You can mount VDO Dotron dots on a rigging truss or similar bar with a diameter of 48 - 51 mm using the
VDO Dotron Half-coupler Rigging Clamp available from Martin® (see “Accessories” on page 35).
To mount a VDO Dotron on a rigging truss:
1. See Figure 5. Pass four grade 8.8 (or
equivalent strength) non-countersunk M4 x 8
mm machine screws or bolts through the four
holes
A in a Dotron Half-Coupler Clamp and
fasten the screws or bolts into the back of the
dot. Use a torque driver to tighten to a torque
of 2.5 Nm.
2. Loosen handle B , open the clamp and pass it
around the chord of a rigging truss. Close the
clamp and fasten handle
B . Make sure that
handle B is tight, but do not use tools: fasten
by hand only.
3. Attach a safety cable or similar secondary
attachment to attachment point C and to a
secure anchoring point so that the safety cable
will catch the VDO Dotron if the primary
attachments fail.
4. Connect the dot’s input connector to the output
connector of the previous device on the link,
either directly or via a patch cable. Make sure
that all connectors are correctly fastened
together with locking rings twisted to ensure a
seal.
5. Check that the dot is held securely before you leave it.
