Install the Switch Chapter 1
Before You Begin
The location where you install the switch must meet these guidelines:
• Operating environment is within the range specified in the technical
specifications. See the Stratix Ethernet Managed Switches Technical Data,
publication
1783-TD001.
• Clearance to front and rear panels meets these conditions:
– Front-panel status indicators can be easily read.
– Access to ports is sufficient for unrestricted cabling.
– Front-panel direct current (DC) power and relay connector is within
reach of the connection to the DC power source.
• Airflow around the switch and through the vents is unrestricted.
To prevent the switch from overheating, use these minimum clearances:
– Top and bottom: 105 mm (4.13 in.)
– Left and right: 90 mm (3.54 in.)
– Front: 65 mm (2.56 in.)
ATTENTION: This equipment is not resistant to sunlight or other sources of UV radiation.
WARNING:
• This equipment shall be mounted in an ATEX-certified enclosure with a minimum ingress protection rating of at least IP54
(as defined in IEC60529) and used in an environment of not more than Pollution Degree 2 (as defined in IEC 60664-1) when
applied in Zone 2 environments. The enclosure must have a tool-removable cover or door.
• This equipment shall be used within its specified ratings defined by Rockwell Automation.
• Provision shall be made to prevent the rated voltage from being exceeded by transient disturbances of more than 140% of the
rated voltage when applied in Zone 2 environments.
• Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other
means provided with this product.
• Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), all connections to this equipment must be powered from a source
compliant with safety extra low voltage (SELV) or protected extra low voltage (PELV).
To comply with UL restrictions, all connections to this equipment must be powered from a source compliant with Class 2 or Limited
Voltage/Current.
