General Warnings - Motorola VSWR Service Manual Supplement

General warnings

General warnings
Introduction
Observe the following warnings during all phases of operation, installation and
maintenance of the equipment described in the Motorola GSM manuals. Failure to
comply with these warnings, or with specific warnings elsewhere in the Motorola GSM
manuals, violates safety standards of design, manufacture and intended use of the
equipment. Motorola assumes no liability for the customer's failure to comply with these
requirements.
Warning labels
Personnel working with or operating Motorola equipment must comply with any warning
labels fitted to the equipment. Warning labels must not be removed, painted over or
obscured in any way.
Specific
warnings
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.
High voltage
Certain Motorola equipment operates from a dangerous high voltage of 230 V ac single
phase or 415 V ac three phase mains which is potentially lethal. Therefore, the areas
where the ac mains 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 mains 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.
RF radiation
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.
Refer to the following standards:
Laser radiation
Do not look directly into fibre optic cables or optical data in/out connectors. Laser
radiation can come from either the data in/out connectors or unterminated fibre optic
cables connected to data in/out connectors.
