7705 SAR-F Installation Guide
Run a single length of #18 AWG wire (minimum) from the ground point (building
ground or equipment ground bus) to the chassis ground stud. When routing the cable,
ensure that there is enough extra wire to form a service loop at the chassis end in order
to facilitate maintenance.
Using a wire-stripping tool, strip the insulation from the wire according to local
safety codes and crimp the ring lug to the wire
Remove the Keps nut and star washer from the ground stud on the mounting bracket.
Place a star washer and the ring lug on the ground stud such that the wire is angled
slightly as it runs down the rack upright
Tighten the nut to a torque of 8-10 lbf-in maximum. Do not over-tighten.
Use a cable tie to secure the ground wire to the lance on the mounting bracket.
Form a service loop with the extra wire and secure it to a convenient place (for
example, a rack upright).
Connect the opposite end of the ground wire to the appropriate ground point at your
installation site. Ensure that the chassis ground connection is made according to local
safety codes.
Connect the 7705 SAR-F to the DC power source. See
