Prepare the RAU

Step 4. Prepare the RAU 1. Remove the access cover from the RAU by unscrewing the
captive thumbscrews at the top and bottom of the unit.
Warning
Do not open the other part of the RAU. To do so voids the
warranty. There are no user/installer fixable parts there.
Opening other parts of the RAU leaves the unit vulnerable to
damage from the environment.
2. Run the RAU cable from the bottom of the junction box to the
RAU. Connect the wire to the RAU using information in Table 8.
See Figure 9 on page 17 for details.
3. Remove the grommet at the bottom right of the RAU and slip it
over the free end of the cable at the end near the connectors, as
shown in Figure 7.
4. The P clip secures the cables in the RAU housing. Using a
Phillips screwdriver, loosen the P clip (Figure 8). Push the cable
through the bottom of the RAU and through the P clip so that the
P clip encircles the cable jacket. Screw down the P clip loosely.
