Before you install
Use authorized utility procedures when installing this device. Equipment damage, personal injury, or
death can result if authorized utility procedures are not followed when installing this device.
For optimal performance of the LAN antenna, Elster recommends that the enclosure be installed so
that it is at least 5 feet (1.5 meters) off the ground. Failure to meet the minimum ground clearance can
result in degraded performance of communications within the EnergyAxis System.
The enclosure is provided with a universal mounting bracket. This bracket allows the enclosure to be
mounted to a pole or building using either bolts or band straps. Choose an installation location that
provides easy access to the cable entry glands and internal enclosure terminations of the cables.
Two keyhole-shaped bolt holes are provided in the bracket (see Figure 4). The keyhole is provided to
allow the fasteners to be partially secured to the installation location before mounting the enclosure.
The head of the fastener can pass through the large opening in the keyhole and allow the enclosure to
be suspended from the fasteners for final tightening.

Three slots are provided in the mounting bracket if band strapping is the preferred mounting method.
These slots can accommodate stainless steel straps up to 5/8 inches wide. The top slot has an open
aperture to allow the first strap to be mounted loosely and allow the enclosure to be suspended from
this strap for easier installation of the other two straps. Elster recommends that all three straps be used
to securely mount the enclosure to its location.
The enclosure must be powered from a 120 VAC to 240 VAC (nominal), 50 Hz or 60 Hz AC power
source.
The enclosure has a weight of approximately 25 pounds (about 11 kilograms).
Placing the device into service
Use authorized utility procedures when installing this device. Equipment damage, personal injury, or
death can result if authorized utility procedures are not followed when installing this device.
For optimal performance of the LAN antenna, Elster recommends that the enclosure be installed so
that it is at least 5 feet (1.5 meters) off the ground. Failure to meet the minimum ground clearance can
result in degraded performance of communications within the EnergyAxis System.
The enclosure is shipped with most of the wiring connections already made. To complete the wiring
and place into service, follow this procedure:
1 Mount the enclosure securely to the pole or structure.
2 Connect the protective earth terminals.
Two connection points are provided on the device. One protective earth grounding to the mounting
bracket; the second provides earth grounding to the enclosure, electronics, and metal components.
Both terminals must be connected to earth ground to ensure safety and reliability. The terminals will
support up to 4 AWG solid conductor.
3 Make all desired communications connections to the module.
Five separate cable gland entry points have been provided to allow cables to enter the enclosure
and route to any or all of the communications and I/O ports. Each cable gland supports one round,
smooth jacketed conductor from 0.354 inches to 0.551 inches in diameter. The gland is large enough
to allow an RJ45 connector to pass through. All communications cable glands have weatherproof
plugs installed from the factory.
To use a particular gland location, simply loosen the outer dome nut and remove the plug. Once a
cable is routed through a gland and terminated, tighten the dome nut on the gland to create a
weatherproof seal.
a Ethernet LAN and WAN: Connections are made by passing an RJ45 terminated cable through a
cable gland and routing it directly to the proper receptacle on the module.
b Serial port: Two adapters are provided in the parts bag for connecting to the serial port of the
module. The included adapters allow for a tight, right angle launch from the device connector and
conversion of the DB9 connector to an RJ45 allowing easy routing through the cable gland (see
Figure 5).

The DB9-to-RJ45 adapter has a straight through pin assignment that maintains the signal
designations of the DB9 connector. This pin assignment is as follows:
Figure 5. DB9 adapters
c I/O terminals: A terminal strip is provided inside the enclosure to allow easy connection. The
terminal locations are identified in Figure 6.
Interposing relay output terminals accept wire sizes from 24 AWG to 10 AWG. The interposing
relays are capable of switching 10 amp loads at 277 VAC or 28 VDC. Ensure connection wire
gauge is sized properly to support the switched load.

Input terminals will accept wire sizes from 24 AWG to 10 AWG. This port consists of 4 optically
isolated discrete input pairs. To make any input active, apply a wetting voltage across the inputs
within the range of 10 V TO 32 V. Each input will draw up to 18 mA at 32 V and down to 4 mA at
10 V. The wetting voltage can be sourced by an external isolated or non-isolated supply. For the
case of an external isolated supply, its ground would not be tied to the ground of the module. A
suggested connection diagram is given in Figure 7.
Figure 6. Interposing relay outputs and input pair terminals
4 Power is applied to the module by a cable that enters the enclosure through the AC line power cable
gland and connects to the AC line surge suppressor. Line power connects to the L1 terminal of the
surge module. Line 2 or neutral connects to the L2 terminal of the surge module. Ground connects to
the GND terminal of the surge module.
5 Insert the DC fuse into the fuse holder.
6 When you are ready to activate the module, close the AC line breaker.
7 Contact your service provider to provision/activate this device on the cellular network. The cellular
modem is shipped with most of the parameters set for proper operation. For more information on
modem configuration and troubleshooting, contact your Elster representative.
8 After completing these steps, verify proper operation. See “Verifying proper operation” on page 8 for
