Installation guide.
Hide thumbs


Remove scarves and neckties, jewelry, and other loose items before you
install the gateway.
Do not remove the gateway cover under any circumstances.


Gateways can generate substantial heat during operation and therefore require
adequate ventilation. You might need to install the gateway in an air-
conditioned room to ensure that its internal cooling system can maintain
acceptable temperatures during operation.
Do not block any ventilation slots on the gateway. Internal components
might overheat and be damaged.
Humidity and Temperature
During operation, ambient relative humidity should never exceed ninety
percent and ambient air temperature must remain between 32
C and 45
Safety Precautions
Follow these safety instructions whenever you are working with the gateway.
Read and follow all of these precautions before you work near any
power source.
Circuit breakers must be installed in the fixed wiring on all circuits to
which the gateways are connected. Ensure that all of the circuit breakers
are easily accessible.
