KDD-PSU Power Supply Unit
3.3 Cautions
The following caution statements identify conditions or practices that can
result in damage to equipment or other property:
• Use correct power source — Do not operate this product from a power source
that applies more than the voltage specified for the product.
• Use correct voltage setting — If this product lacks auto-ranging power supplies,
before applying power ensure that the each power supply is set to match the
power source.
• Provide proper ventilation — To prevent product overheating, provide equipment
ventilation in accordance with installation instructions.
• Use anti-static procedures — Static sensitive components are present which
may be damaged by electrostatic discharge. Use anti-static procedures, equipment
and surfaces during servicing.
• Do not operate with suspected equipment failure — If you suspect product
damage or equipment failure, have the equipment inspected by qualified service
personnel.
• Ensure mains disconnect — If mains switch is not provided, the power cord(s) of
this equipment provide the means of disconnection. The socket outlet must be
installed near the equipment and must be easily accessible. Verify that all mains
power is disconnected before installing or removing power supplies and/or options.
• Route cable properly — Route power cords and other cables so that they are not
likely to be damaged. Properly support heavy cable bundles to avoid connector
damage.
• Use correct power supply cords — Power cords for this equipment, if provided,
meet all North American electrical codes. Operation of this equipment at voltages
exceeding 130 VAC requires power supply cords which comply with NEMA
configurations. International power cords, if provided, have the approval of the
country of use.
• Use correct replacement battery — This product may contain batteries. To
reduce the risk of explosion, check polarity and replace only with the same or
equivalent type recommended by manufacturer. Dispose of used batteries
according to the manufacturer’s instructions.
• Troubleshoot only to board level — Circuit boards in this product are densely
populated with surface mount technology (SMT) components and application
specific integrated circuits (ASICs). As a result, circuit board repair at the
component level is very difficult in the field, if not impossible. For warranty
compliance, do not troubleshoot systems beyond the board level.
