Important Safety Instructions
It is important to remember that the PCS100 is designed to supply power even when it is disconnected
from the power grid. The interior of the PCS100 is unsafe until the DC power source is disconnected
and the AC/DC inputs are disengaged. It is recommended to wait a period of at least five minutes for
capacitor bleed-off before attempting to service any components.
Before attempting any work around the PCS100, observe the following precautions:
Remove any watches, rings, or other metallic accessories.
Only use tools with insulated handles.
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of the cabinet.
Read the “Safety Instructions” on page ix on the first at the beginning of this manual before
performing any service on the components. Ignoring safety instructions may result in injury,
damage or death.
DANGEROUS VOLTAGE LEVELS MAY BE PRESENT FOLLOWING DISCONNECTION. DO NOT OPEN THE
CABINET UNTIL A REASONABLE PERIOD OF TIME HAS ELAPSED.
