Installation
Console Placement
TV-80 consoles are HEAVY. A fully loaded 70 position mainframe
can easily weigh 600 lbs. We recommend using at least six people to
move and place the console.
Console placement should avoid proximity to any electromagnetic
fields, such as large power transformers, motors, and fluorescent
lighting fixtures. The console may be mounted either on a custom
constructed table surface or the optional factory leg support system. In
either case, the console's handrest top surface would generally be
located 29-30 inches from the floor.
Do not connect the TV-80 console to its power supply (and do
not connect the power supply to the AC power line) until instructed
to do so.
Factory Leg Support System
The optional factory leg system supports the console at sitdown
height, and provides a hidden internal wiring chase that may be closed
off with a rear concealment panel. The leg support system is pre-
assembled at the factory, then broken down for shipment. Field
assembly instructions are included in a separate document supplied
with the legs. They are also reproduced in Appendix II of this Technical
Manual (see page A-8).
System Ground
The first step is to ground the console.
Note that as supplied from the factory, console rackmount power
supply common, audio common, and the TV-80 mainframe are con-
nected together at the console, but are NOT connected to electrical
ground and the chassis of the power supply. Safety requirements
dictate that a positive connection from the console mainframe to
electrical ground be made in the completed installation. Use one of the
grounding lugs on the bottom of the mainframe to establish your
system ground. The grounding lug terminal strip may be found at the
rear of the console, along the bottom edge of the mainframe pan directly
under the rightmost mainframe slots (to the extreme lower left if you
are looking at the rear of the console).
