Installing the PAD-5-MB to the Enclosure (See Figure 2)

  1. The enclosure is installed in its proper place.
  2. The knockout locations for passing through cables have been removed.
  3. Install the power supply. The size of the power supply is determined by the battery calculation spreadsheet, (See the Battery Size Calculation section). Use the four (4) #10/32 nuts provided in the power supply package. Refer to the power supplies installation sheet for additional information. See Figure 3 for details.
  4. Install the Adapter Plate with the PAD-5 Main Board on the four (4) #10-32 studs of the enclosure and use the 10-32 hex nuts that are provided to secure the adapter in place.
  5. Run AC through the left side knockout. See the Wire Routing section. Connect the wires as shown in the AC Wiring section (Figure 6). Tie Earth to the Ground Lug located near the power supply. Do not connect the power supply to the PAD-5-MB until all configuration jumpers are set, and any option module (if installed) is mounted and secured.
  6. Wire all terminal blocks according to the following sections for the P2, NAC, NAC Follower, and Aux. Do not connect power until all field wiring is complete. Use the knock out drawing in the Wire Routing section (Figure 5).
  7. If no expansion module is being used, make sure the factory installed daughter bypass card is plugged into X901. If it is not, P2 communication troubles will be annunciated at the FACP. Also, the daughter bypass card has polarity, so pay attention to the markings on the module, for proper placement in case the card is taken out.
  8. Before applying power, the address needs to be set on the PAD-5-MB (and the expansion card if using one). Do not have the expansion module connected to the PAD-5-MB when programming the address, because it will get the same address as the PAD-5-MB. Program the expansion module apart from the PAD-5-MB. The DPU programs the address of the PAD-5-MB, since the PAD-5-MB is considered a loop device. See DPU programming section for more details.
  9. Next, install the batteries (7AH and 18AH fit inside the 1HU enclosure, up to 35Ah batteries can be installed in the 2HU enclosure). Use the provided battery cable assembly that comes with the PAD-5-MB to connect the batteries.
  10. For Seismic applications, the maximum battery size for both enclosures is 18Ah and requires the use of the Battery Bracket FHA2032-U1 (P/N S54430-B43- A1). In order to use larger batteries, a separate battery box CAB-BATT (P/N 500-633917) black, or (P/N 500-634925) red, must be used.

Remember, connect the power supply to X100 first, then connect the batteries to X101. When servicing the panel, the order is opposite. Disconnect the batteries, then the power supply.
