DC POWER INPUT:
Connect your DC power cable to the 2P Amphenol FCC17 D-SUB Connector (male). Secure the cable to the hex
spacers provided on the unit, and secure the other end to your power supply. The internal DC power module supports
24VDC and is part of the Multipower functionality for the unit.
GROUNDING SCREW:
Please review “General Installation Chapter”, pt. 6 for more information.
Multi-power note: (For units supporting AC & DC input simultaneously)
The unit has a dual input power supply which will accept both AC and DC input. If both inputs are connected, the
unit will be powered by AC. If AC is disconnected it will automatically switch over to DC without affecting the operation
of the unit. This makes it possible to use AC power as primary power and a 24V battery as secondary power,
eliminating the need for expensive UPS systems.
