Warnings particularly applicable to the equipment are positioned on the
equipment and within the text of this manual. These must be observed by all
personnel at all times when working with the equipment, as must any other
warnings given in text, on the illustrations and on the equipment.
Certain Motorola equipment operates from a dangerous high voltage of 230 V
ac single phase or 415 V ac three phase supply which is potentially lethal.
Therefore, the areas where the ac supply power is present must not be
approached until the warnings and cautions in the text and on the equipment
have been complied with.
To achieve isolation of the equipment from the ac supply, the ac input isolator
must be set to off and locked.
Within the United Kingdom (UK) regard must be paid to the requirements of the
Electricity at Work Regulations 1989. There may also be specific country
legislation which need to be complied with, depending on where the equipment
is used.
High RF potentials and electromagnetic fields are present in the base station
equipment when in operation. Ensure that all transmitters are switched off when
any antenna connections have to be changed. Do not key transmitters
connected to unterminated cavities or feeders.

Toxic material
Because of the danger of introducing additional hazards, do not install substitute
parts or perform any unauthorized modification of equipment. Contact Motorola
if in doubt to ensure that safety features are maintained.
Do not wear earth straps when working with standby battery supplies.
Certain equipment may incorporate components containing the highly toxic
material Beryllium or its oxide Beryllia or both. These materials are especially
hazardous if:
Beryllium materials are absorbed into the body tissues through the skin,
mouth, or a wound.
The dust created by breakage of Beryllia is inhaled.
Toxic fumes are inhaled from Beryllium or Beryllia involved in a fire.
Beryllium warning labels are fitted to equipment incorporating Beryllium or
Beryllium Oxide. Observe all safety instructions given on warning labels.
Beryllium Oxide is used within some components as an electrical insulator.
Captive within the component it presents no health risk whatsoever. However, if
the component should be broken open or burnt, the Beryllium Oxide, in the form
of dust or fumes, could be released, with the potential for harm.

Devices sensitive to static
Devices sensitive to static
Introduction
Certain metal oxide semiconductor (MOS) devices embody in their design a thin
layer of insulation that is susceptible to damage from electrostatic charge. Such
a charge applied to the leads of the device could cause irreparable damage.
These charges can be built up on nylon overalls, by friction, by pushing the
hands into high insulation packing material or by use of unearthed soldering
irons.
MOS devices are normally despatched from the manufacturers with the leads
shorted together, for example, by metal foil eyelets, wire strapping, or by
inserting the leads into conductive plastic foam. Provided the leads are shorted
it is safe to handle the device.
GSM-204-020
Special
handling
techniques
In the event of one of these devices having to be replaced, observe the
following precautions when handling the replacement:
Always wear an earth strap which must be connected to the electrostatic
point (ESP) on the equipment.
Leave the short circuit on the leads until the last moment. It may be
necessary to replace the conductive foam by a piece of wire to enable the
device to be fitted.
Do not wear outer clothing made of nylon or similar man made material. A
cotton overall is preferable.
If possible work on an earthed metal surface. Wipe insulated plastic work
surfaces with an anti-static cloth before starting the operation.
All metal tools should be used and when not in use they should be placed
on an earthed surface.
Take care when removing components connected to electrostatic sensitive
devices. These components may be providing protection to the device.
10
When mounted onto printed circuit boards (PCBs), MOS devices are normally
less susceptible to electrostatic damage. However PCBs should be handled with
care, preferably by their edges and not by their tracks and pins, they should be
transferred directly from their packing to the equipment (or the other way
around) and never left exposed on the workbench.

considerations
GSM-204-323
There must be adequate clearance at the front of (648 mm), and above
(1900 mm), the equipment for operation and maintenance purposes. It is also
recommended that there is adequate side clearance to open the doors to 120°
(see Figure 1-5), and to fit the optional shroud on the cable entry side.
The foundation or structure on which the BTS cabinet is mounted must be of
sufficient strength to withstand 105 knot (120 mph) winds on the cabinet front or
rear and a maximum gross weight of 360 kgs.
The cabinet ventilation entry and exhaust is solely from the bottom front of the
cabinet, allowing a cabinet to be placed against a wall. However, a minimum
clearance of 240 mm is required on the cable entry side, between the cabinet
and obstructions, such as a wall or another cabinet.
Allow 1000 mm clearance at front and side where possible, to facilitate
installation and maintenance.
NOTE
In seismically active areas, Motorola suggest using a
qualified structural engineer to assess frame mounting
requirements, such as floor construction, mounting
anchors and cell site construction.
