ADCP-61-814 • Issue 1 • April 1999 Note: PWR-AVIS units configured with the single powering option can be upgraded to redundant power by ordering an additional power supply module (PWR-AVIS-PSC). The PWR-AVIS provides two sets of screw terminal contacts (see Figure 8) at the rear of the chassis for connecting to a -48V office power supply. Alternately, a 110-48V (PWR-AVIS- 110-ST) converter (purchased separately) can be attached to either set of contacts. 2.2.2 Alarms As shown in Figure 8, PWR-A
