the control surface connectors (it doesn’t matter which one). If you are
using the failsafe option (two PSU-1 supplies), connect one end of a
power supply cable to either control surface power connector and
connect the other end of the cable to one of the two power supply
connectors. Then use the other cable to connect the second power
supply connector to the remaining control surface power supply
connector.
Note 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.
Failsafe Dual Redundant Supply
Wheatstone failsafe power supply systems use two PSU-1 power
supplies for each piece of powered equipment. Though either is
capable of running a full load on its own, in failsafe operation both units
run in tandem: if one fails, the other takes over, assuring uninterrupted
operation.
In order for failsafe systems to perform as designed, always have
BOTH rackmount supplies powered up and connected to their associ-
ated equipment.
Energizing
Assuming the D-7 control surface mainframe is properly placed,
and its PSU-1 power supply (or supplies) correctly rackmounted and
connected to the control surface, you may now energize the rackmount
power supply by plugging it into the AC mains. The “GOOD” LEDs
on the power supply front panel should light up to indicate the presence
of their respective voltages. The control surface's LED meters will
illuminate and individual module switches will assume factory default
settings.
Note: To de-energize the control surface, unplug the rackmount
power supply’s AC cord from the AC mains. Never de-energize the
control surface by disconnecting the cable that connects the control
surface and power supply together.
Once you have verified proper power-up, unplug the rackmount power
