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.
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.
