See the specications for power requirements. Apply low voltage to the

four-pin removable keyed connector using one the powering methods.

DC Powered

The unit accepts 10–36 VDC. The “0Vdc” connection is connected to

chassis within the unit. Input connections are reverse-voltage protected.

Redundant DC Powered

For backup power, redundant diode-isolated DC power inputs are provided.

Either power supply must be capable of powering the unit. Do not assume

that input currents from the two supplies will be balanced.

AC Powered

The AI-SRVR can be powered by 8–24 VAC from the secondary of a

low-voltage transformer. If using a grounded secondary transformer,

refer to Figure 10. If needed, two auxiliary power supplies are available

from Contemporary Controls: the AI-XFMR is for 120 VAC primary

power and the AI-XFMR-E uses 230 VAC.

AC Powered with Battery Backup

You can apply power from both an AC and DC source (usually a battery).

If the AC source fails, the unit will operate from the battery — but separate

provisions are required for charging the battery.
