Installing the Mini Doubler
To install the HDU-217 or the HDU-219 in an enclosure, refer to the
installation manual of the enclosure for information about:
•
Cabling
•
Proper connections
•
Grounding
•
Line and local power
All wiring external to the product(s) should
follow the provisions of the current edition of
the National Electrical Code.
Once the HDU-217 or HDU-219 is installed in the enclosure, the
front-panel LED flashes and then lights a steady green. If the LED
continues to flash, or changes colors, refer to"Fault Isolation," in this
practice.
The HDU-217 and HDU-219 doubler units can be housed in a variety
of outdoor apparatus cases manufactured by various vendors. The
capacity of the doubler units in several of these standard enclosures is
listed in Table 2, Table 3, and Table 4. The number of doubler units
that can be plugged into each enclosure is limited by mandatory
thermal constraints. The constraints are imposed to avoid overheating
that may result in damage to the doubler units.
