Mounting
The FRE-765 mounts on a pole or a wall. Follow local practices to ensure a secure mounting. Mount the FRE-765
for easy access to the cable entry points on the bottom of the enclosure. Provide ample room to open the door
completely.
For pole mounting the FRE-765, use the Pole Mounting kit, part number FMK 2397 List 1. Follow the instructions
that are included to install the pole mounting bracket. Then mount the FRE-765 to the bracket. Do not install any
cabling until the FRE-765 is securely mounted.
When required, install the grommet into the base of the FRE-765 (see Figure 2, “Installing the Grommet,” on page
7 ) prior to performing any wiring. Table 7, “Grommet Hole Diameters,” on page 7 shows the wire gauges that you
can install through the holes in the grommet):
1 Select only one concentric knockout hole on the FRE-765.
2 Remove the largest knockout so that the entire hole is open.
3 Install the grommet from the outside of the FRE-765. (Hint - Hold it at an angle to the hole and roll it into
position.)
4 Ensure that the lip of the grommet rests on the bottom of the FRE-765 around the knockout hole.
5 Use an appropriate tool to open the required hole(s) in the bottom of the grommet.
