Conditioned Power Center

On both removable side panels, near the top of the panel and approximately in the middle are the following warn-
ings. Each calls attention to a specific hazard requiring special attention.
With the front panel circuit breaker of the power conditioner turned off and locked out, pot entially hazardous
touch voltages are confined to the input power conductors at the rear of the circuit breaker. Entering the cabinet
under these circumstances is classified as a Type 4 task under SEMI S2-0200 guidelines. This hazard label
alerts personnel to the need to turn off and lock out power to the power conditioner at the facility source. Doing
so will eliminate all potentially hazardous voltages inside the enclosure. Entering the enclosure under these cir-
cumstances if a Type 1 task under SEMI S2-0200.
PLEASE NOTE: After extended operation, internal parts of the power conditioner may become very hot.
This hazard label calls attention to the need for protective gear when entering the equipment enclosure.
Inside the power conditioner enclosure another warning similar to the one
shown at the left warns once again of the presence of very hot surfaces
and the potential for injury and burns. This warning is accompanied by
the legend “CAUTION - HOT SURFACE” and is attached to the upper steel
frame of the isolation transformer on the primary side.
