Notes:
• AC power must be provided to the 4100U-S1 from a dedicated AC branch circuit.
The AC input is supervised wiring.
• The AC branch is terminated in the cabinet in the general power output (GPO)
mounted in the expansion bay. The SPS plugs into the GPO via a 3-pin plug and
mains lead.
• A mains fail fault is generated when the DC voltage drops below 20.3V (nominally at
mains voltage 204VAC).
