SPECIFICATIONS
Standalone OCMs may be operated from a 24 VDC, 120/220 VAC, or 125 VDC input power
source (subject to Power Option specified at time of ordering... see Ordering Information).
The Auxiliary 120/220 VAC or 125 VDC power supply is attached to the side of the Standalone
OCM enclosure. The Auxiliary Power Supply P2 Connector is hardwired at the factory to the
Standalone OCM Base Enclosure J5 connector. This cable brings the necessary regulated power
supply voltages from the Auxiliary Power Supply into the base OCM electronics. This cable should
never be removed or modified in any way. Also, no other connection should be made to either the
OCM P2 or J5 connectors.
The Auxiliary 24 VDC power supply is mounted inside the main enclosure.
1.3.4.1.1 AUXILIARY POWER SUPPLY SPECIFICATIONS
The Auxiliary Power Supply must be ordered as an option to the Standalone, Panelmount OCM
module.
