SRX550 Services Gateway Grounding Specifications
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the
SRX550 Services Gateway must be adequately grounded before power is connected. You must provide
a grounding lug to connect the services gateway to earth ground.
WARNING: Before services gateway 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 services gateway (for example, by causing a
short circuit).
To ground the services gateway before connecting power, you connect the grounding cable to earth ground
and then attach the lug on the cable to the chassis grounding point, using the screw.
Table 24 on page 76 lists the specifications of the grounding cable used with the device.
