V erify that the site is ready for BTS installation before performing the physical installation.
A detailed layout of the site is provided with the site -specific documentation. Before installing
the hardware, compare the information presented here to the site -specific documentation layout
and verify with the Site Manager for the following:
• All cable trays are installed.
• All external signal cables are connected.
• Site is clean.
• Site specific documentation covering all site dependent installation information is available.
• The installation area has restricted access. Equipment is meant to be installed and
operated in a restricted access location. In order to maintain UL listing, equipment must
be installed in a restricted access area.
• The site can maintain the required temperature range.
• The layout meets the minimum clearance requirements for the equipment as listed in
T able 2 -5 , T able 2 -6 and T able 2 -7 .
• All building DC power cables are connected.
• The building meets the voltage and power requirements shown in
