Wiring Instructions

This chapter describes how to perform the system wiring and cabling procedures.
Read the Safety section first follow the rule carefully before doing any wring 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 are OFF or disconnected before servicing.
The Delta PCS100 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 to opening the enclosure door.
WARNING!
!
Grounding: All input and output circuits are isolated from the enclosure. System grounding,
when required by EN 62477-1, is the responsibility of the installer.

Opening/Closing the Enclosure Doors

Disconnect Position: The AC and DC disconnects on the front door have an interlock
mechanism to prevent the front door from being opened if it is not in their OFF position. Turn
the disconnects to OFF position before opening/closing the doors. Turning the disconnects
clockwise sets them to ON (vertical) position, while turning the disconnects counter
clockwise sets them to OFF (horizontal) position.
