Site requirements and considerations

CONTROLLED INTRODUCTION
Inst. 1–11
Structural
considerations
Adequate clearance must be provided at the front of the equipment for
operation and maintenance purposes. There must be adequate side clearance
(50 mm) to enable the door to open beyond 90° (see Figure 1-1). The door can
also stop at 95° and 130°, but this is only to protect the door, or give optional
additional operator space.
The cabinet ventilation entry can be solely from the bottom front of the cabinet.
This allows a cabinet to be placed against a wall. However, if the unit is placed
50 mm from back or side obstructions, such as wall or other cabinets, the
ventilation will be improved, and fan noise reduced.
Up to 100 mm rear space may be required for cables if using stacking bracket.
The foundation or structure on which the BTS cabinet is mounted must be of
sufficient strength to support a maximum gross weight of 130 kg for a single
cabinet or 280 kg for two stacked cabinets.
NOTE
In seismically active areas, Motorola suggest using a
qualified structural engineer to assess frame mounting
requirements, such as floor construction, mounting
anchors, cell site construction and to provide a suitable
design for top frame support if a stacked configuration is
required.
