Cabinet Weight Table

In addition to the Indoor location considerations, the following
additional items should be considered when choosing a Rooftop
location:
Loading Considerations (also see Table 2-2):
– A single SC 4812ET RF Cabinet can weigh up to 680 kg. (1500
lbs) and a single Power Cabinet enclosure can weigh up to 1590 kg.
(3500 lbs) with the batteries installed (batteries are shipped
separately). Expansion enclosures and optional equipment will add
weight (refer to the introduction section of this manual for obtaining
detailed information on the optional equipment).
– When the cabinet is to be roof mounted, be sure to consider the rain
and/or snow loading of the region when determining whether the
roof can support the load.
Zoning requirements – that relate to building mounted equipment
should be checked for any restrictions that may affect cabinet or antenna
placement.
Adequate clearance through doors, passageways and stairwells to allow
movement of the cabinet from the delivery area to the installation site.
Minimum separation distance – Every effort should be made to
minimize the separation distance between the RF and Power Cabinet
(see Table 2-1).
Table 2-2 lists the approximate weight of both the RF and Power
cabinets in various site configurations.

WARNING
Roof load carrying limits must be reviewed and an
appropriate support structure must be installed to support
the cabinets as required.
CAUTION
The cabinets must be elevated sufficiently above the roof
surface to prevent water from puddling around its base.
Although the cabinets are well insulated from the
environment they will not tolerate submersion.
NOTE
The Power Cabinet as shipped without batteries installed
can weigh up to 544 kg (1200 lbs.).
