SEL-8300 Installation
Securely mount the SEL-8300 using four 1/4 inch-sized (6.0 mm) fasteners (not
included) designed for the surface to which the unit is being attached. To protect the
polycarbonate material of the Wireless Interface, use a flat washer in conjunction with
each fastener. We recommend that you install each fastener with a torque of 25 in/lbs
not to exceed 50 in/lbs. Install the SEL-8300 vertically to ensure optimal integral
antenna position and to maximize the life of the integral lithium battery.

Standard SEL FCI lead lengths for magnetic probe outputs are 12 feet. Additional lead
lengths can be specified. Mount the SEL-8300 in a location that provides access to all
FCI magnetic probes. The R
ADIORANGER system communicates via 900 MHz; to
improve the range, install the SEL-8300 in locations with few RF impediments, such as
below a grate, if possible. Additionally, RF performance will be compromised in vaults
where flooding can occur. In vaults where flooding is common or where the FCI lead
