Revision P4
• Unplug the equipment from the AC power outlet before cleaning. The outside of the
equipment may be cleaned using a lightly dampened cloth. Do not use any cleaning
liquids containing alcohol, methylated spirit or ammonia.
• Do not use accessories or attachments not recommended by the manufacturer, as they
may cause hazards and will void the warranty.
• Install the equipment on a flat and stable surface.
• Route power supply cords and interconnecting cables so that they are unlikely to be
walked on or pinched by items placed upon or against them. Pay particular attention
to cords at plugs, convenience receptacles, and the point where they exit from the
unit.
• Never insert objects of any kind into the unit through openings, as the objects may
touch dangerous voltage points or short out parts. This could cause fire or electric
shock.
• When replacement parts are required, ensure that the service technician uses replace-
ment parts specified by the manufacturer. Unauthorized substitutions may damage the
unit or cause electric shock or fire, and will void the warranty.
• Always turn the power off and wait 5 seconds before disconnecting or connecting any
cables to the IDU.
• Do not short or overload any output connectors or cables, these may cause a serious
damage to the unit and will void the warranty of the unit.
• Upon completion of any service or repair to the unit, ask the service technician to per-
form safety checks to ensure that the SIT is in proper operating condition.
• For continued protection against fire hazard, replace all fuses only with same type and
rating.
• Do not operate the system in the presence of flammable gases or fumes. Operation of
any electrical system in such an environment constitutes a definite safety hazard.
• It is recommended to place the series 3000 IDU over a thermal conductive surface
during normal operation. Please avoid polyethylene foam or other similar thermal
insulating materials.
1.6.3 Protection Against Electrostatic Discharge
• Static electricity can harm delicate components inside your equipment. To prevent
static damage, discharge static electricity from your body before you touch any of
your equipment’s electronic components, such as the microprocessor boards. You can
do so by touching an unpainted metal surface on the grounded equipment chassis. As
you continue to work inside the equipment, periodically touch an unpainted metal
surface to remove any static charge your body may have accumulated. You can also
take the following steps to prevent damage from electrostatic discharge (ESD):
• When unpacking a static-sensitive component from its shipping carton, do not
remove the component from the anti-static packaging material until you are ready
