2. INSTALLATION
This device is intended to be used as part of an automated utilities meter reading network
and uses proprietary communications and data to communicate with another host device.
2.1. INTERNAL USE
This device was designed to fit into The Elster Electricity LLC REX2 series of utilities electric
meters. Provisions in the case mechanics have been provided to accept the device as an
insert-able option card. The interface connector is designed to mate directly with the main
board in the electric meter. This device is installed when the electric meter is manufactured at
the factory.
All additional required FCC testing and control for proper operation to meet FCC
requirements as a final product have been met.
2.2. EXTERNAL USE
This device is not for sale to the general public.
Sale of this device outside of the company will be strictly controlled to ensure its compliance.
2.3. CLEARANCE
The device should be installed in a manner such that a clearance distance of 8mm will be
maintained from the front and back of the device to prevent adversely affecting the antenna
incorporated onto the Circuit Board.
Antenna testing in the intended host device did not show any significant deterioration in
performance caused by close proximity of wiring or case mechanics. Good engineering
practice dictates that the antenna be kept clear of obstacles to ensure maximum
performance.
