Installing an IFU
IFUs are installed in the locations as specified by each site drawing. A
near-end IFU is the first installed IFU in a pair, and the far-end IFU is the
second in the pair. Figure 3-10 provides a close-up view of an installed IFU.
Installing an IFU is a two-part process:
1 Mounting the IFU to the mounting bracket.
2 Attaching cables to the IFU.
Mounting the IFU
Verify the correct IFU for location by checking the product number on the
IFU against the site drawing in the site engineering folder.
