General
Within the EnergyAxis
®
and Connexo systems, the EA_Gatekeeper is the intelligent interface between
the EnergyAxis Management System (EA_MS) and Connexo NetSense and the local area network
created by the gatekeeper (referred to as the EA_LAN). As the interface, gatekeepers are equipped with
WAN and LAN communication capabilities. Depending on the need, utilities have options when
choosing how to deploy gatekeepers into service. For example, the gatekeeper can be installed in an
A3 ALPHA
®
meter if revenue metering is required at a particular site. If deploying meter-based
gatekeepers is neither feasible nor desired, the gatekeeper can be enclosure-mounted in different
form factors.
This leaflet explains how to install the gatekeeper model 2210.
This model of EA_Gatekeeper is configured for 120 VAC to 277 VAC (nominal) operation and uses a
battery backup for gatekeeper operation if AC power fails at the site. The EA_Gatekeeper model 2210
uses a NEMA-4X rated polycarbonate enclosure. The gatekeeper supports different mounting options,
including mounting on 18-foot (5-meter) to 35-foot (11-meter) utility poles.
Because of the self-discharge rate of the system backup battery, this product must be powered up
within 60 days of receiving. If the battery drops below 11.25 VDC for an extended period, the battery
might need to be charged with a shop charger or need to be replaced.
