PM = Pipe Mount
For pipe mounting, a bracket, C-clamp and safety cable are
provided and must be used to secure the dimmer pack to
standard pipe sizes from 1" to 2" (1.25" to 2.375" outside
diameter).
WARNING: Ensure the pipe is secure and rated adequately
for local rigging codes.
Ensure the safety cable is fastened correctly to
secure the dimmer pack.
WM = Wall Mount
For permanent applications, the dimmer pack can be mounted
to any wall surface capable of supporting its weight. Using the
four (4) mounting holes provided, 1/4" (6mm) screws or bolts
are required to fasten and secure the rack safely to the wall.
WARNING: Never mount the dimmer packs side by
side (vertically) without a minimum of 12"
of clearance between them. Always leave a
minimum of 6" of clearance from the dimmer
packs air intake and exhaust. Failure to comply
may cause thermal overheating.
RM = Rack Mount
For rack mounting, brackets are provided and used to secure
the dimmer pack in a standard 19" rack.
WARNING: Ensure there is sufficient ventilation provided
when mounting multiple dimmer packs within a
19" rack. The internal ambient temperature of
the rack must not exceed 104°F (40°C). Failure
to comply may cause thermal overheating.
Ensure there is adequate rear support provided
to maintain the dimmer pack position inside the
19" rack.
