SRX110 Services Gateway Grounding Specifications
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, the services gateway must be adequately grounded before power is
connected. A grounding point available on the rear of the services gateway chassis is
used to connect the device to earth ground.
WARNING: Before device installation begins, a licensed electrician must
attach a cable lug to the grounding and power cables that you use. A cable
with an incorrectly attached lug can damage the device (for example, by
causing a short circuit).
To ground the device before connecting power, you connect the grounding cable to earth
ground and then attach the lug on the cable to the chassis grounding point with the
screw.
Table 44 on page 133 lists the specifications for the grounding cable used with the device.
