    The hinged meterbridge will require 14” above the countertop surface and 4 3/4” behind the rear meterbridge to open freely. Do not connect the A-2000 console to its power supply (and do not connect the power supply to the AC power line) until instructed to do 7.6341...

  • Page 10: System Ground

    The first step is to ground the console. Note that as supplied from the factory, console rackmount power supply common, audio ground, and the A-2000 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.

    Once the system is properly grounded, proceed with the console power supply installation and connection (next section). Power Supplies The A-2000 console is powered by a Wheatstone Model PSC-D340 If failsafe redundant sup- rackmount power supply. This heavy duty unit occupies three 19” wide...

    BOTH rackmount supplies powered up and connected to their associ- ated equipment. Energizing Assuming the A-2000 console mainframe is properly placed and grounded, and its PSC-D340 power supply correctly rackmounted and connected to the console, you may now energize the PSC-D340 rackmount power supply by plugging it into the AC mains.
