If required, tally, GPI, or relay wiring entering equipment racks may connect via terminal blocks (Cinch 140
- 142 Series) or on Entrelec blocks; terminal blocks will be fully exposed, labeled, and mounted on 3/4 inch
plywood board painted flat black. If Qty of terminals is too numerous to fit in rack, terminal blocks may be
located on wall mounted plywood terminal board adjacent to rack. Mounting boards to be 3/4 inch A/C
grade or hardwood plywood painted flat black. Terminal board wiring to meet the same requirements as
internal rack wiring described below.
Connect audio cable to active components through screw terminal connections whenever available. Make
connections to speaker transformers with properly sized closed end connectors crimped with factory
approved ratchet type tool. Wire nut or "Scotchlock" connectors are not acceptable. Do not wrap audio
cable splices or connections with adhesive backed tape.
Connect loudspeakers electrically in phase, using the same wire color code for speaker wiring throughout
the project.
Wiring and connections will be completely visible and labeled in rack.
All power cables will run on the left side of the equipment rack, as viewed from the rear. All other cables
will be run on the right side on the equipment rack, as viewed from the rear. Where signal cabling and any
cabling types carrying power must cross, they will do so at right angles. Vertical wiring will be run with a
bundling and support system, to maintain a clear and organized appearance.
Horizontally routed wiring to equipment will be neatly tied in manageable bundles with cable lengths cut to
minimize excess but still allow ready access for service and testing. Provide horizontal support bars if cable
bundles sag
For equipment mounted on slides, additional service loops will be provided to accommodate the full range
of travel of the slides. This includes all power, ground, control and signal cables. All cables, accept power,
must be wrapped in flexible expandable sleeving to avoid snagging or entanglement.
For short/thin chassis patch bays, cables are to be integrated in a “z” style service loop to allow the patch
bay to be “hinged” outward from the front of the rack for maintenance.
Neatly bundle excess AC power cables from rack-mounted equipment with plastic cable ties. Rack wiring
to be bundled with plastic cable ties or lacing twine. Electrical tape and adhesive backed cable tie anchors
are not acceptable. Cable tie and lacing installation will be accomplished using hand tools specifically
designed to apply proper tension to the cable tie, and to cut it off flush with no protruding sharp edges.
Cable ties will not be applied with excessive force, which may damage or deform sensitive and fragile
cables.
All cables in cabletrays shall be neatly installed with maintaining separation of the different cable types.
Required production room cable paths and lengths must be predetermined especially in instances where
timing is a factor. The information that is essential for the implementation of this task is as follows:
Site Survey
Floor and Ceiling Plans
Elevation Design
Equipment List
Video and Audio Schematics
Cable Trays and Conduits
Screw Connections: Only insulated crimp on spade terminals will be used for application to barrier strips.
Multiple gang lugs or ring lugs are not acceptable for this purpose.
