Connect the Power Cables
Depending on your situation, there are three options available for supplying power
to the SBV5506 chassis. Select from one of the following:
• Facility Power 120 VAC – Choose from one of the following two
options:
> “Connecting the AC Facility Power Source (Hardwire)” on
page 18
> “Connecting the AC Facility Power Source (Power Cable to
Indoor 120 VAC Outlet)” on page 20
• 90 VAC from HFC Plant – Power the unit using a tap and the plant
cable as the power-generating source. For more information, see
“Connecting the AC HFC Power Source” on page 23.
• UPS DC – Power the unit using an uninterruptible power source
(UPS). For more information, see “Connecting the UPS DC Power
Source” on page 25.
For outdoor installations, only use a UPS that is approved for outdoor
usage.
CAUTION: Although different power configurations are available, only
one powering option can be used at a time. When servicing requires the
equipment to be powered down, make sure all power sources have been
disconnected.
