Electrical Grounding
The gateway must always be connected using a grounding-type plug.
Warning
Make sure that the facility where the gateway is installed has proper
electrical grounding and is connected to that ground at all times during
operation.
Protection Against Lightning
Warning
Do not work on the gateway during an electrical storm. Do not connect or
disconnect any wires, including network or power connections. Whenever
the threat of lightning danger exists, avoid touching the gateway. This
precaution is sensible for any electrical device during periods of lightning
activity.
Electrical Power Source
Warning
Do not open the gateway or remove the network interface card (NIC) from
the gateway. No user-serviceable or user-replaceable parts are present in
the gateway. Only authorized service personnel should repair or open the
gateway.
Warning
To reduce the risk of fire, electric shock, and injury, disconnect the power
cord and any cables that connect to the gateway before you open the
chassis and expose internal components. Even though the power switch
is turned off, power is still present inside the gateway.
