SRX220 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 lug on the back 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 supply. 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 29 on page 65 lists the specifications of the grounding cable used with the device.
