System Capacity
To determine power supply loading, add together all of the user stations that will be powered from a particular buss (less
stations which are self-powered).
NOTE:
The SAP612 distributes DC power, but uses no power itself. Refer to the power supply manual for power supply
capacity information.
Intercom Channels
Connect intercom channels to the OUTPUTS 1-12 jacks on the rear panel. Each connector accommodates a pair of TW
channels wired in the standard TW 2-wire configuration as follows:
Pin 1 Common (low side of line)

Shielded cable is recommended for user stations interconnections. Connect shields to circuit common, but do not tie shields to
chassis, earth or connector shell ground.
