2.3 Electrical Connection
WARNING - In order to protect personnel responsible for operation , service
and maintenance of this Power Supply and to protect equipment within the
network, all installation sites MUST be provided with an earth ground bonding
connection to the Power Supply bonding terminal. A reliable ground bonding
connection also helps to protect the Power Supply from damage of high-energy
transients, e.g. lightning strike.
The impedance between the Power Supply enclosure and earth must be 25 Ohms or
less. Soil conditions may affect the grounding system meeting the 25 Ohm
(maximum) resistance specified above. Please contact a local grounding system
expert if required.
AC Output Connection:
Output connection of the power supply is made through the 5/8" x 24 coaxial female
connector located on the bottom panel of the Power Supply.
A mating male cable connector appropriate for the coaxial hardline to be used must have
the center pin prepared as follows:
Screw the male cable connector (external fitting) into the 5/8" female connection. The
center pin is automatically seized by the female connector. Prepare and attach the coax ial
hardline feeding the HFC plant to the male cable connector as per the manufacturer's
instructions.
AC Input Connections:
An external service disconnect (UL listed) MUST be installed between the Utility power
and APX2PLUS-615G Power Supply. The disconnect device is provided by the user. Please
consult the local supplier, supplier of the service disconnect and your local utility for
specific installation instructions and guidelines. All electric al codes apply.
Before attempting to connect the input supply wiring, ensure that the disconnect is in the
disconnect (off) position. Using an RMS voltmeter, confirm that no voltage exists at the
disconnect output.
The Utility power connection is made through the Power Supplies cable gland to the
input terminal block. Ensure that no strands of bare wire are outside of the terminal
block. Tighten each terminal screw with sufficient torque to ensure a good electrical and
mechanical connection.
