Table 23 on page 82 lists the specifications of the grounding cable used with the device.
Table 23: Grounding Cable Specifications for the SRX650 Services Gateway
SpecificationGrounding Requirement
8 AWG wire cableGrounding cable
Up to 25AAmperage of grounding cable
Panduit LCCX8-14A-L ground lug, or equivalent
CAUTION: For the NEBS compliant installation in an AC or DC
system, use a ground wire of at least 8 American Wire Gauge
(AWG). The ground wire must have an agency-approved crimped
two holes connector attached to one end, with the other end
attached to the building ground. The connector must be crimped
with the proper tool, allowing it to be connected to both ground
screws on the enclosure. Before crimping the ground wire into the
ground lug (Panduit LCCX8-14A-L), ensure that the bare copper
wire is cleaned and antioxidant is applied to the bare wire.
CAUTION: To ensure adequate bonding when attaching the
ground lug, a minimum of 26.6 in-lbs of torque must be applied
to the mounting hardware that is used to attach the ground lug.
CAUTION: When making the primary ground connection, metric
M5 screws with star/lock washer must be used for anti-rotation.
When connecting the deviceto the rack frame, use thread-forming
screws and paint-piercing washers.
