Wiring Instructions
This chapter describes how to perform the system wiring and cabling procedures.
Read the Safety section first and follow the rules carefully before doing any wiring and cabling works to
ensure personal safety.
Safety
Shock Hazard: Ensure that no DC voltage is being supplied to the PCS and that no AC
voltage is present on the AC wiring. Failure to do so could cause serious injury or death. A
warning label is provided to inform all personnel that multiple sources of power are available
inside. This label is installed on the outside of the door and should remain clearly visible.
Ensure all sources of power are OFF or disconnected before servicing.
The Delta PCS100HV contains electrical components carrying potentially lethal voltages
and currents. Extreme caution should be exercised around the system, especially when the
cabinet door is open once it's installed. Before opening the cabinet, all supply power should
be disconnected using a standard physical lock-out procedure and the service personnel
should wait 5 minutes prior toopening the enclosure door.
WARNING!
Grounding: All input and output circuits are isolated from the enclosure. System grounding,
when required by IEC/EN 62477-1, is the responsibility of the installer.
