Note that each power supply is fitted with a 3-wire grounded AC cord
that should be plugged into a "clean" AC power source, that is, an AC
source that feeds only the control room audio gear. This source should be
a separate feed from those powering lighting, air-conditioning, or any
other non-audio machinery. The third pin ground wire of the AC source
should be tied to the central system ground point. Note that while the AC
power cord ground wire terminates at the power supply chassis, it does
NOT connect to the RD console common; the console itself must be
grounded separately. (See previous section, "System Ground".)
The VU/Timer Cable
Connections from the MOD-5 Meter Output Module to the Meterbridge
for VU meter and timer signals are made through a special cable that ships
with the console. This cable has a DB-25 at the one end and two 12-pin
AMP type connectors at the other end. Connect the DB-25 connector to
the matching DB-25 connector on the underside of the Meterbridge at the
back of the console. Connect the two AMP type connectors to connectors
A and B on the bottom of the frame at the slot that contains the MOD-5
module (the connectors on the cable are labeled “A” and “B”).
Energizing
Assuming the RD console mainframe is properly placed and grounded,
and its SPS-180R power supply correctly rackmounted and connected to
the console, you may now energize the SPS-180R rackmount power
supply by plugging it into the AC mains. The console's individual module
switches will assume factory default settings.
Note: To de-energize the console, unplug the rackmount power
supply’s AC cord from the AC mains. Never de-energize the console by
disconnecting the cable that connects the console and power supply
together.
Once you have verified proper power-up, unplug the rackmount power
supplies to de-energize the console. You may now proceed to wire up audio
and control connections.

The power feed recom-
mended in the text is of-
ten installed and referred
to in studios as an “iso-
lated AC ground” outlet.
It is usually orange in
