in the site-specific documentation have been installed and previously
checked for meeting the site-specific documentation specifications.

any customer-specific options.
The interface of the alarms to the Motorola equipment will be part of the
cell site equipment installation.
Temperature control
Verify with the site manager that the cell site building has been
previously checked for the ability to maintain a temperature range as
specified by Motorola. The life span of electronic equipment is
shortened by environmental variations, even though it is designed to
operate in extreme temperatures.
For external installations
For outside installations refer to the site specific documentation.
For internal installations
For indoor installations refer to the Grounding Guideline for Cellular
Radio Installations (68P81150E62) for all grounding inspection
procedures.
Verify the following:
S
All ground cables have a bend radius of 20 cm (8 inches) or more.
S
Metallic lines (span, phone[modem], RGPS, power and antenna) that
enter or leave the site should be equipped with a 3-electrode gas tube
protector. The ground side of the gas tubes should be tied to the
Master Ground Bus (MGB). This is not necessary if your site is
equipped with the Primary Surge Suppressor.
S
All installed cable racks (in the same ground zone) are jumpered
together.
WARNING
Cable racks in an Isolated Ground Zone (IGZ) are not to be
connected to a cable rack in a non-IGZ. For more
information on IGZ, see Grounding Guideline for Cellular
Radio Installations, Motorola part number 68P81150E62.
