Guidelines
The PDI-772HE-IND is a specialized power supply designed to power low-voltage AC small screen televisions and
is intended for use in a hospital, a nursing home, a medical-care center, or a similar healthcare facility in which
installation is limited to a non-hazardous area in accordance with the National Electrical Code ANSI/ NFPA70.
This installation should be made by a qualified service person and should conform to all local codes.
Do not attempt this installation without an assistant.
Location
The supply is mounted in a utility or electrical closet near an AC wall outlet. Due to coaxial cable length
restrictions, select a location that limits the longest coaxial cable run, that is the distance between the supply and
furthest room, to a maximum of 150 feet. Refer to the section titled
CATV Wiring
for coax cable
recommendations.
Cooling
This power supply is engineered for high efficiency. Please observe these guidelines.
1.
Select a location with a maximum ambient room temperature of less than 100°F.
2.
Allow a minimum clearance distance of 8 inches on top, bottom, and both sides of the power supply cabinet.
This clearance is required for cooling. Do not cover or obstruct ventilation grills on the cabinet as this
supply utilizes convection cooling. For example, the supply should NOT be mounted in a drop ceiling due to
the restricted airflow that occurs in such a tight air space.
3. Do not route cables between the wall and back of the power supply. The back of the supply must be kept
clear to allow for convection air cooling.
4. The supply when under full load will generate approximately 110 watts of waste heat. Please consider the
installed location
’
s additional temperature rise caused by operation of this supply.
Electrical
This power supply requires a 120 VAC circuit capable of supplying 10 amperes of current. Do NOT use an
extension cord with this power supply.
