The SPS and RPS get their power from the Power Distribution Module (PDM). The PDM takes
power directly from a dedicated AC line and the two backup batteries, and distributes power to each
bay in the cabinet.
The power distribution module (PDM) connects to the SPS, RPS, or XPS in each bay. One PDM is
used per back box. Use the instructions below to properly connect the PDM to each bay.
1. Route the Black and White AC power wires to the supplied ferrite bead. Loop the wires
twice through the bead as shown below:
Figure 4. Wire Loops through Ferrite Bead
2. Wire 120/220/230/240 VAC to the PDM, keeping AC wires at least one inch away from all
other wires. AC power must stay in the right side of the cabinet, in the non-power-limited
area.
3. Connect batteries to P5 on the PDM using Harness 734-015.
