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.
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.
D
EATH, SERIOUS INJURY, OR HARDWARE DAMAGE CAN RESULT IF CAUTION IS NOT TAKEN.
Maintenance should only be performed by qualified personnel.
Lethal voltage is present in the PCS100. The unit must not be operated with the front
door doors open. At no time should you make any assumptions of the electrical state of
the PCS100.
