3) Any adjustment, maintenance and repair of the opened equipment powered up must
be carried out by a skilled person who is aware of the hazards involved
4) Servicing personnel should be trained against unexpected hazards.
5) Ensure that only fuses with the required rated current and of the specified type are
used for replacement. The use of makeshift fuses and short circuiting of fuse holders
is prohibited.
1.4 Static Electricity
The unit supplied may use static sensitive devices and service personnel should be
alerted to components which require handling precautions to avoid damage by static
electrical discharge.
Before handling circuit board assemblies containing these components, personnel should
observe the following precautions:
1) The work surface should be a conductive grounded mat.
2) Soldering irons must be grounded and tools must be in contact with a conductive
surface to ground when not in use.
3) Any person handling static sensitive parts must wear a wrist strap which provides a
leaky path to ground, impedance not greater than 1 megaohm.
4) Components or circuit board assemblies must be stored in or on conductive foam or
mat while work is in progress.
5) New components should be kept in the supplier’s packaging until required for use.
1.5 Disposal Hazards
Service personnel should be aware that batteries should be disposed of intact and never
incinerated.
1.6 Load Inductance
Low voltage D.C. power supply products connected to large inductive loads can store
sufficient energy in the load to cause an electrical hazard. Extreme caution is
recommended when switching such circuits as back EMFs can reach dangerous levels.
