install mounting hardware and brackets:
Step 1.
Install truss hooks (also refer to "Truss Hook Hardware (by oth-
ers)" on page 23) for additional information) on two provided
truss hook brackets as required as shown in Figure 2-7.
NOTE: Various types of truss hooks can be used. The Mega Claw truss
hook (as shown in the example above) as well as many other standard
hooks, can be ordered separately.
Truss HOOK HarDWare (BY OTHers)
When installing hanging hooks on mounting brackets, Vari-Lite strongly
recommends the use of a Belleville washer when installing a truss hook or
claw. The Belleville washer's size should be approximately 13-25mm (0.5-
1.0 in) diameter. Belleville washers are available in various thicknesses
and any of the following thicknesses are acceptable for the application
described: 0.9.mm, 1.0mm, 1.3mm, 1.9mm (0.035-inch, 0.043-inch, 0.050-
inch, 0.073-inch).
The washer serves two purposes:
• to spread out the load. When a washer IS NOT used, the bolt
head (without a washer) concentrates the load in a smaller
area, creating focused stress on the steel bracket, making premature failure possible. A steel washer is
recommended to spread this load over a larger surface area.
• to keep the bolt in place. The recommended Belleville washer maintains tension in the bolted assembly
and prevents it from vibrating loose.
If a Belleville washer is not available, a regular flat washer measuring in diameter of 25mm (1 inch) minimum can
be used in conjunction with a suitable split lock washer situated between the bolt head and flat washer.
Step 2.
Determine required configuration of bracket installation. Brackets may be installed in many different
orientations.
Step 3.
While pulling up on locking mechanism release, fit keyed holes onto raised mounting buttons at bot-
tom of enclosure. Slide forward and release locking mechanism to lock in place. Ensure brackets are
locked securely.
WARNING: Ensure that the bracket locking mechanism is fully seated after the bracket is installed on the
luminaire.
installing in truss:
Step 1.
Using two people, lift luminaire into mounting position.
Step 2.
Secure in place with truss hook. Ensure truss hook hardware that locks hook in place (e.g. wing bolt) is
properly tightened and that luminaire is fully supported.
