Safety Issues of Power Supply Installation and Use
The subject power supply has been designed and built to power CATV and broadband
distribution equipment only. It is not intended for any other usage and provides output
voltages suitable only for its intended application.
distribution equipment only. It is not intended for any other usage and provides output
voltages suitable only for its intended application.
Power supplies documented in this instruction manual use more than one source of power.
If any reason exists to open the power supply enclosure for maintenance or adjustments,
first turn off the BATTERY CIRCUIT breaker on the front panel, disconnect the AC line cord
from its outlet and remove the BATTERY connector from its receptacle on the front panel.
Be certain that at least 5 minutes has elapsed before opening covers after disconnecting
operational power.

DANGER
This power supply operates from either a 120 volt or 240 volt AC source and produces
internal voltages in excess of 500 volts. DO NOT open any covers or panels or attempt
to perform any service to the power supply without first removing and disconnecting all
external AC and DC power sources. Only trained, qualified personnel should attempt
service and repair work on the power supply.
internal voltages in excess of 500 volts. DO NOT open any covers or panels or attempt
to perform any service to the power supply without first removing and disconnecting all
external AC and DC power sources. Only trained, qualified personnel should attempt
service and repair work on the power supply.
Install only gelled electrolyte valve regulated lead acid (VRLA) or AGM type batteries as a
standby DC source for this power supply. See the following Battery Safety Issues for
further information.
The power supply must be installed within a cabinet suitable for accommodating CATV
power supplies. If installed outdoors, the cabinet must have a 3R (rainproof) rating as a
minimum requirement. See the following Enclosure Safety Issues for further information.
Enclosure Safety Issues
The cabinet and the power supply must be installed by qualified technicians or installers
only. Whether using ground-mount or pole-mount option, appropriate mounting hardware
meeting local codes and construction practices must be used. Failure of fasteners over the
service life of the cabinet may result in hazardous conditions for the general public who
may pass near the installation.
The outer cabinet housing the power supply must be of adequate strength to support the
power supply and its associated batteries. Additionally, the cabinet must afford adequate
ventilation for the power supply such that a minimum free air space of 2-inches remains
around all sides and the top of the power supply. Air intake at the front of the inverter
module must remain unobstructed.
Temperature of the air entering the inverter module and flowing around the power supply
must not exceed 60 degrees Celsius. Air intake and exhaust openings within the outer
cabinet must not be less than 40 square inches in area. If these limits are exceeded or
