length is insufficient for optimal installation, order SEL-8300 units with an optional
remote antenna that provides an extra 15' of lead length. For best results, orient the
omni-directional antenna vertically so that it points toward the surface.

Power
The SEL-8300 is equipped with two dials: a power switch and an ID selector. The
smaller dial, labeled PWR, controls the power and has two positions. When the arrow is
pointing up, the SEL-8300 is on. When the arrow is pointing down, the unit is off. The
unit is shipped in the off position to conserve battery energy. The SEL-8300 is powered
by a 20-year shelf life lithium D cell. SEL designed the R
ADIORANGER system to
optimize battery life without compromising RF range. As such, the SEL-8300 is
expected to provide 15 years of service life under normal operating conditions.
Wireless Interface ID Selection
The larger dial on the SEL-8300, labeled ID, allows the user to select one of eight
wireless interface IDs. The Wireless Interface ID is part of the communications string
between the SEL-8300 and SEL-8310 and identifies which ID(s) the Remote Fault
Reader is communicating with. Therefore, the user should select different IDs if
installing multiple SEL-8300 units within a 150-foot radius. Doing so prevents
communications collisions with the SEL-8310, which could create a source of
confusion for the operator. It is important to situate the ID selector within one of the
eight detent positions in the SEL-8300 housing, to ensure proper ID selection.
Additionally, the ID could serve as a customer-specific naming convention to indicate
the nature of certain installations. For example, certain IDs could represent specific
vault configurations, voltages classes, etc. Another example of a naming convention is
to have odd-numbered IDs represent circuits arranged in a North-South direction, and
even-numbered IDs represent circuits arranged in an East-West direction.
