Power Supply Options
Your Sonoma can be configured with several optional power supply inputs which are listed in
Appen-
dix H - Specifications
. Dual-redundant power supplies are also available.
DC Power Input
The DC power input uses a a 3-position terminal block and replaces the standard AC power input
jack.

Connecting the DC Power
Connect the safety ground terminal to earth ground. Connect the “+” terminal to the positive output
of the DC power source. Connect the “-” terminal to the negative output of the DC power source.
Note that the Sonoma has a “floating” internal power supply, therefore either the positive or negative
output of the DC power source can be referenced to earth ground. This unit will not operate if the +/-
connections are reversed; however it will not be damaged by a reverse connection.
SHOCK/ENERGY HAZARD
Install in Restricted Access Location.
Use 10-14 AWG copper wire only.
Terminal block screw torque: 9 lb-in (1 n•M).
Branch circuit must have circuit breaker, 15A or less.
Power must be sourced via two pole disconnect device.
Install terminal block cover after wiring.
Dual-Redundant Power Supplies
Any combination of Universal AC and/or DC supplies is available. Primary and secondary power
supplies are connected in a dual-redundant configuration with hitless automatic primary-to-secondary
and secondary-to-primary switchover.
A fault detector monitors the status of each redundant power supply. When a fault is detected it will
trigger a system alarm. When Sonoma is configured with Dual Power Supplies, an alarm will show if
the primary or secondary supply does not have power connected.
