Logic and other circuitry requiring +5 V is powered from an external,
regulated +5 V dc supply when the data option is not installed. The external
power supply must meet the following specifications:
Input: 95–129 V ac, 60 Hz
Output: +5 V dc, + or –5%, 300 mA
10 mV maximum RMS ripple
Cord: 2.5 m (8 ft.) of 20 AWG wire mating to a Switchcraft 722A
connector
Case: Wall mounted, CSA and UL approved.
Operational within 0°C (32°F) and 50°C (122°F)
temperature limits
Impedance: Greater than 10 M¾ to ground
The external power supply, in all cases where no Asynchronous Data Option
is installed, is connected to the mating connector mounted in the rear of the
M2317 telephone, covering the area where the RS-232-C interface connector
would be located.
Note: If the Asynchronous Data Option is installed, an external,
multi-output data power supply (refer to NPS50220-03L5) is required.
See "Data options" on page 85 for more information on ADO
requirements.
