Battery replacement
Where internal batteries are fitted they should be replaced with the recommended type and
be installed with the correct polarity to avoid possible damage to the equipment, buildings
and persons.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. After the
completion of test, to discharge capacitors the voltage should be gradually reduced to zero
before the test leads are disconnected.
Insertion of modules and PCB cards
Modules and PCB cards must not be inserted into or withdrawn from the equipment
whilst it is energized, since this may result in damage.
Insertion and withdrawal of extender cards
Extender cards are available for some equipment. If an extender card is used, this should
not be inserted or withdrawn from the equipment whilst it is energized. This is to avoid
possible shock or damage hazards. Hazardous live voltages may be accessible on the
extender card.
Fiber optic communication
Where fiber optic communication devices are fitted, these should not be viewed directly.
Optical power meters should be used to determine the operation or signal level of the device.
Cleaning
The equipment may be cleaned using a lint free cloth dampened with clean water, when no
connections are energized.
DECOMMISSIONING AND DISPOSAL
Decommissioning
The supply input (auxiliary) for the equipment may include capacitors across the supply or to
earth. To avoid electric shock or energy hazards, after completely isolating the supplies to
the equipment (both poles of any dc supply), the capacitors should be safely discharged via
the external terminals prior to decommissioning.
