5 – Troubleshooting and System Tests
After the problem has been located and repaired, refer to Sequence of operation on page 56 to test the power supply for
proper operation.
WARNING!
ELECTRIC SHOCK CAN KILL
Turn OFF (O) the power and disconnect the electrical power before removing the cover
from the power supply. If the power supply is connected directly to a line disconnect box,
switch the line disconnect to OFF (O). In the U.S., use a “lock-out / tag-out” procedure
until the service or maintenance work is complete. In other countries, follow appropriate
national or local safety procedures.
Do not touch live electrical parts! If power is required for servicing, use extreme caution
when working near live electrical circuits. Dangerous voltages exist inside the power
supply that can cause serious injury or death.
Do not attempt to repair the power board or control board. Do not cut away or remove any
protective conformal coating from either board. To do so risks a short circuit between the
AC input circuit and the output circuit and may result in serious injury or death.
HOT PARTS CAN CAUSE SEVERE BURNS
Allow the power supply to cool before servicing.
MOVING BLADES CAN CAUSE INJURY
Keep hands away from moving parts.
STATIC ELECTRICITY CAN DAMAGE CIRCUIT BOARDS
Put on a grounded wrist strap before handling printed circuit boards.
