Notes on 19" rack mounting
Increased ambient temperature
When installed in a closed rack or a rack unit with several devices, the ambient temperature of
the rack may be higher than the room temperature. Install the devices in an environment
compatible with the maximum ambient temperature specified by the manufacturer.
Reduced air flow
Install the devices in a rack so that there is an adequate air flow for the reliable operation of the
devices.
Mechanical load
When installing the devices in a rack, avoid the dangers of unequal mechanical load.
Circuit overload
When connecting the devices to the power supply, avoid the effects of circuit overload on the
overcurrent protection and the power supply cables. Take into account the rated values on the
nameplate of the devices.
Reliable grounding
Devices mounted in racks must be reliably grounded. Pay particular attention to supply
connectors that are not directly connected to the circuit branch (e.g. socket strip).
