NOTE: The P300MT cannot be retrofitted for the Quick Restart Option (QRO).
Routine Maintenance
The only maintenance required on the power supply is periodic cleaning. The service
interval will vary depending on the environment in which the unit is operated.

WARNING: Exercise extreme caution; the chassis weighs up to
40.3 kg (88.6 lbs.)
All high voltage capacitors have internal discharge resistors
which should discharge to a safe level in 5 seconds. Physically
shorting the capacitor terminals with an insulated screwdriver
blade is advised as a second level of safety.
CAUTION: The integrated circuits on the control board
assembly can be damaged by relatively small charges of static
electricity. Static charges transmitted by fingertip (for example,
those generated by walking across a carpet) may be sufficient
to cause damage. Always touch a grounded metal surface
before removing or examining the control card.
