Install the RAUs and Antennas

InterReach Spectrum Remote Access Unit Installation Guide Page 9

NOTE: RAUs are suitable for use in environmental air space in accordance with Section

300-22(c) of the National Electrical Code, and Sections 2-128, 12-010(3) and 12-100 of

the Canadian Electrical Code, Part 1, CSA C22.1.

NOTE: You can place the RAU, without its fastening hardware, on a flat surface, such as a shelf,

desk, cabinet, or any other horizontal surface that allows stable placement, with the

mounting base facing down to the mounting surface.

CAUTION! If installing the RAU on a flat surface, the surface must be able to hold a minimum

7-pound load securely.

1 Mount all MRAU and SRAUs in the locations marked on the floor plans.

2 Install the passive antennas according to the manufacturer’s installation

instructions.

NOTE: It is common practice to install passive antennas below the ceiling. If you install a

passive antenna above the ceiling, when estimating the antenna coverage area, account

for additional loss due to the ceiling material.

3 Connect a passive multi-band antenna to the N connector on each RAU using

coaxial cable with the least amount of loss possible. (See

“Appendix C: Omni

Antenna” on page 21 for information on the Omni Antenna ports.)

CAUTION! Firmly hand-tighten the N connector. DO NOT over-tighten the connector.
