Figure 59: Grounding Points On The Acx500 Indoor Router - Juniper ACX500 Hardware Manual

NOTE:
In the ACX500 indoor routers, the grounding points are located on the
front left of the router.
In the ACX500 outdoor routers, the grounding points are located just
below the power inlet port.
The location of the grounding points on the ACX500 routers is the same
for both the AC and the DC variants.
For the ACX500 outdoor routers, perform the following additional steps as
rust-preventative and corrosion-preventative measure:
Clean both the mating surfaces (the grounding cable lug and the ACX500 outdoor
a.
router grounding terminals).
Apply a thin film (0.04 in. or 1 mm) of corrosion-preventing compound, such as
b.
NO-OX-ID, on the ACX500 outdoor router's grounding terminals.
Press the lug onto the conductive surface unit in order to force out the excess
c.
corrosion-preventing compound.
Secure the grounding cable lug with the washers and screws. The holes are sized for
8.
SAE 10-32 screws. Apply 4 lb-in. (0.49 Nm) of torque to each screw. Do not overtighten
the screw (use a number 2 Phillips screwdriver). See
Figure 58 on page 136.

1— Grounding lug
CAUTION: Ensure that each grounding lug sits flush against the surface
of the grounding points as you are tightening the screws. Ensure that each
screw is properly threaded into the grounding points. Applying installation
torque to the screw when improperly threaded can damage the terminal.
CAUTION: The maximum torque rating of the grounding screws on the
router is 4 lb-in. (0.49 Nm). The grounding screws can be damaged if
excessive torque is applied. Use only a torque-controlled driver to tighten
