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 SPS-180 or
SPS-400 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-9 control surface mainframe is properly placed,
and its PSR power supply (or supplies) correctly rackmounted and
connected to the control surface, you may now energize the PSR
rackmount power supply by plugging it into the AC mains. The control
surface's LCD displays 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.
