Elster EnergyAxis Gatekeeper 2210 User manual

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.

Before you install
Use authorized utility procedures when installing the EA_Gatekeeper model 2210. Equipment
damage, personal injury, or death can result if authorized utility procedures are not followed when
installing the EA_Gatekeeper model 2210.
The EA_Gatekeeper model 2210 is a FCC Part 15 Class A device, and it is not intended for installation in
or on a residence. See the FCC Part 15 Class A compliance statement on page 9.
For optimal performance of the LAN antenna, Honeywell recommends that the EA_Gatekeeper model
2210 be installed so that the enclosure is at least 5 feet (1.5 meters) off the ground. Failure to meet the
minimum ground clearance can result in degraded performance of the EA_Gatekeeper model 2210
communication within the EnergyAxis or Connexo systems.
The EA_Gatekeeper model 2210 supports different mounting options, including mounting on 18-foot (5-
meter) to 35-foot (11-meter) utility poles. Be sure to follow your utility's instructions for mounting the
gatekeeper at its installation location.

EA_Gatekeeper model 2210 Ethernet backhaul 4
The EA_Gatekeeper model 2210 is designed to operate from a 120 VAC to 277 VAC (nominal) power
supply. Power is routed through the AC line power entry gland and the wires land on the screw
terminals located on the bottom side of the SPD module. The screw terminals should be torqued to 6
inch-pounds (0.678 Newton-meters). The cable entry gland dome nut must be torqued to 20 inch-
pounds (2.26 Newton-meters).
To maintain the NEMA 4X integrity to the device, steps must be taken to ensure proper sealing of the
enclosure features. The cable used for the Ethernet communications and for powering the gatekeeper
must be a smooth, round-jacketed, outdoor rated cable. The enclosure lid screws must be installed in
the corners of a lid and torqued to 5 inch-pounds (0.565 Newton-meters). These screws are provided
in the parts bag attached to the inside of the enclosure lid. This product is equipped with an anti-
condensation heater and must configured in the field before mounted on a pole (see “Placing the
EA_Gatekeeper model 2210 into service” on page 5).
The enclosure should not be opened when ambient temperatures fall below 32 °F (0 °C). Opening the
enclosure lid when temperatures are below freezing may result in damage to the enclosure lid gasket
and compromising the seal. If the enclosure must be opened when temperatures are below freezing,
first gently warm the enclosure around the lid gasket to ensure the gasket is not frozen to the sealing
surface.
LAN communications
The gatekeeper supports different antenna options. If the antenna is mounted on the unit itself (that is,
a local external antenna), no additional steps are required when placing the gatekeeper into service.
If the gatekeeper is to be installed at a location that requires a greater height to overcome blocked
signals, a remote antenna is required.1Placing the gatekeeper into service requires mounting the
remote external antenna in a suitable location. The antenna should be mounted in the clear, as free
from conductive or metallic obstructions as possible. The connectors should be sealed for
waterproofing.
Do not use a standard RG-8/U cable with solid polyethylene dielectric. The losses in solid dielectric
RG-8/U cables in short distances make solid dielectric RG-8/U cables unacceptable.
For assemblies that use a remote mounted antenna, be sure to waterproof the RF cable terminations
(such as, using coax sealant) to help prevent water entering the cable terminations.
This device has been designed to operate with the antennas listed below and having a maximum
gain of 5.15 dBi. Antennas not included in this list or having a gain greater than 5.15 dBi are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.
1. Remote antennas and cables are not supplied with this device. Your Honeywell sales engineer can
help you order the correct antennas and cables.

EA_Gatekeeper model 2210 Ethernet backhaul 5
Remote external antennas: PCTEL/MAXRAD P/N MFB9380 (Tessco P/N 61900) for unity gain (2.15 dBi);
PCTEL/ MAXRAD P/N MFB 9153 (Tessco P/N 74300) for 3 dB gain (5.15 dBi)
There are several options for remote antenna cabling. The most economical connection to the external
remote antenna is the LMR-400 type cable. This type of cable is suitable for distances up to 100 feet
(approximately 30 meters). Antenna cables should be ordered with the N-type male connectors on
each end. One end attaches to the gatekeeper housing, and the other end attaches to the antenna.
You can perform on-site assembly or order pre-assembled cables (for example, from Laird
Technologies).
WAN communications
The EA_Gatekeeper model 2210 is equipped with an Ethernet communications option board. This
option board is connected to an internal Ethernet surge suppressor. The external Ethernet device cable
is routed through the Ethernet cable gland and connected into the bottom of the Ethernet surge
suppressor. The cable used must be rated for outdoor use, have a minimum CAT 5 rating, and have
EMI/RFI shielding with conductive RJ-45 connectors. The cable shielding is connected to ground on the
EA_Gatekeeper side and should be left ungrounded on the external equipment side to prevent a
ground loop scenario.
Placing the EA_Gatekeeper model 2210 into service
Use authorized utility procedures when installing the EA_Gatekeeper model 2210. Dangerous
voltages are present. Equipment damage, personal injury, or death can result if authorized utility
procedures are not followed when installing the EA_Gatekeeper.
The EA_Gatekeeper model 2210 is a FCC Part 15 Class A device, and it is not intended for installation in
or on a residence. See the FCC Part 15 Class A compliance statement on page 9.
Be sure to properly ground the EA_Gatekeeper before placing the gatekeeper into service.

Although the EA_Gatekeeper model 2210 supports nominal power supply ranges from 120 VAC to
277 VAC, you must identify the power supply at the installation site to properly configure the gatekeeper
for operation.

power input.

3 Following your utility's authorized procedures; mount the device at the installation location.
4 Connect protective earth to the bracket (19) and to the service post (19) at the bottom of the enclosure.
5 If you are using a remote antenna option, mount the external antenna and route the cable through
the lightning arrestor bulkhead (18). Use coax sealant to waterproof these connections.
6 Apply AC power as appropriate for the intended AC power operation. Power is applied to the
gatekeeper by a cable that enters the enclosure through the base of the unit (20) and connects to the
AC line SPD (11).
After completing these steps, verify that the EA_Gatekeeper is operating correctly.
