control room equipment (HOST). You must remove the cover from the IR4000S
enclosure to access these connectors. The inside of the cover includes a label that lists
the function of each connector location.
WARNING:
For safety, ground cabling must always be connected first, before other
cabling is connected. The 24 VDC power cabling should be connected last (and
disconnected first). Power supply connections to the IR4000S must remain OFF until all
wiring is completed and the start-up readiness checklist has been verified. Refer to the
manual for the power supply being used for instructions.
