Note

Refer to “Fiber Optic Port Specifications” on page 29 for additional information on the fiber optic port.

Selecting a Site

Be sure to observe the following guidelines when selecting a site for your bridging converter.

Select a site that is dust-free and moisture-free.

Select a site that will allow you to easily access the data cables and power cord.

Use dedicated power circuits or power conditioners to supply reliable power to the device.

Use the power sources as described in “External Power Supply” on page 3.

For 12-50VDC version, provide regulated DC power only from SELV sources per IEC 60950, such as regulated power supplies.

Note

Use only power sources that are UL Listed (QQGQ or EPBU), TUV Licensed or other Safety Agencies approved, suitable for country of use.
