SRX210 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 48 on page 159 lists the specifications of the grounding cable used with the
device.
