of the equipment documentation, or otherwise required by local or country wiring
regulations.
The protective conductor (earth) connection must be low-inductance and as short
as possible.
Before energizing the equipment, the following should be checked:
- Voltage rating/polarity (rating label/equipment documentation);
- Protective fuse rating;
- Integrity of the protective conductor (earth) connection (where
applicable);
- Voltage rating of external wiring, applicable to the application.
Equipment use
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Equipment operating conditions
The equipment should be operated within the specified electrical and
environmental limits.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. At
the end of each part of the test, the voltage should be gradually reduced to zero,
to discharge capacitors, 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Modules and PCB cards must not be inserted into or withdrawn from the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.
Fibre optic communication
Where fibre 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. Contact fingers of test plugs are normally
protected by petroleum jelly, which should not be removed.
2.4 De-commissioning and disposal
De-commissioning
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 de-
commissioning.
Disposal
It is recommended that incineration and disposal to water courses is avoided.
The equipment should be disposed of in a safe manner. Any equipment
containing batteries should have them removed before disposal, taking
precautions to avoid short circuits. Particular regulations within the country of
operation, may apply to the disposal of the equipment.
