Appendix B: Safety Information
EMG™ Edge Management Gateway User Guide 462
Input Supply
Caution: Disconnect all power supply sources before servicing to avoid electric
shock.
Check nameplate ratings to assure there is no overloading of supply circuits that could affect
over current protection and supply wiring.
Grounding
1. Maintain reliable grounding of this product.
2. Pay particular attention to supply connections when connecting to power strips, rather than
directly to the branch circuit.
Rack Mounting
If rack mounted EMGs are installed in a closed or multi-unit rack assembly, they may require
further evaluation by Certification Agencies. The following items must be considered:
Do not install the EMG unit in a rack in such a way that a hazardous stability condition results
because of uneven loading. A drop or fall could cause injury.
The ambient temperature (Tma) inside the rack may be greater than the room ambient
temperature. Make sure to install the EMG in an environment with an ambient temperature
less than the maximum operating temperature of the EMG unit. See Hardware Specifications
(on page 39).
Install the equipment in a rack in such a way that the amount of airflow required for safe
operation of the equipment is not compromised.
Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven
mechanical loading.
Maintain reliable earthing of rack-mounted equipment. Give particular attention to supply
connections other than direct connections to the branch circuit (e.g. use of power strips).
Before operating the EMG, make sure the EMG unit is secured to the rack.
Wall Mounting
If wall-mounted units are installed, the following items must be considered:
Do not install the unit in such a way that a hazardous stability condition results because of
uneven loading. A drop or fall could cause injury.
Make sure to install the EMG unit in an environment with an ambient temperature less than the
maximum operating temperature of the EMG unit. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
Maintain reliable earthing of wall-mounted equipment. Give particular attention to supply
connections other than direct connections to the branch circuit (e.g. use of power strips)
because of the effect that overloading of the circuits might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
Before operating the EMG, make sure the device mounting is secured.
