Section 5: Installation and Setup
Installing and wiring any model within the Blackhawk Series power supplies into an
enclosure may be accomplished as simply as connecting input and output wiring to the
appropriate connectors of the power supply. If wired for 120 volt AC input, the AC power
cord of the power supply mates with a standard 5-20R 120 volt, 20 amp outlet. The
230/240 volt version of the power supply requires a standard 6-15R AC outlet. All other
connectors on the front panels of the modules mate with industry-standard connectors
widely available and used within the CATV industry. Moreover, connectors used in this
power supply mate with accessory harnesses and assemblies designed and manufactured
by Multilink Broadband. Refer to the OPTIONS section of these instructions for further
information.
This power supply is designed for use in both existing and new enclosures of either pole or
ground-mount configuration. Observe the following procedures during installation of any
Blackhawk Series power supply.
Preparation:
The Blackhawk Series power supplies have been factory assembled, tested and prepared
as a complete product ready for installation within an enclosure. The installer must verify
that the correct type of AC power receptacle is installed in the enclosure for the input
service and power supply selected for use at any given site. Additionally, the correct
battery must be installed in the enclosure since the power supplies are fabricated and
adjusted for 36 or 48 volt DC input, exclusively. Power supply ratings may be verified from
the nameplate on the left side panel near the power cord.
1) Check to ensure that the correct system output voltage has been selected. The
output voltage select terminal board is located behind the left-side front panel,
allowing the user to choose output voltage of 60, 75 or 90 volts. If the output voltage
must be changed from its factory setting, refer to the SERVICE section of these
instructions for VOLTAGE RECONFIGURATION.
2) Additionally, verify that the correct battery string has been installed in the enclosure
for 36 or 48 volt battery input. Check the nameplate of the power supply or the
interior of the inverter module to determine that the DC input voltage requirements
match the configuration of the system.
Placement in the Enclosure:
This power supply has been designed primarily for use within a cabinet or enclosure
offering protection from outdoor weather, entry of excessive dust, dirt or moisture and from
unauthorized contact by untrained personnel. If used in a controlled environment, the
power supply may be located within an indoor equipment cabinet or may be mounted on a
rack shelf.
