ELECTRICAL POWER REQUIREMENTS
The power supply requires a fused, single-phase, standard 3-terminal
grounding type receptacle capable of supplying the requisite voltage and
current. (Standard 120 volts or optional 220 volts, 50/60 Hz, regulated
between 95-135 volts or 190-265 volts, respectively.)
SETTING UP
The power supply is a free-standing assembly. It should be installed in a clear,
uncluttered location that is free from excessive dirt, dust, corrosive fumes, and
temperature and humidity extremes. The selected installation site should be
near the electrical power source and away from equipment that generates
abnormally high electrical transients. Observe the following additional
instructions when installing the equipment:
a. Allow at least 6 inches (152.4mm) at the rear of the power supply for cable
connections.
b. Position the power supply so that the front panel controls are visible and
readily accessible.
c. The power supply is air cooled; allow sufficient space around the assembly
to ensure adequate ventilation. If the power supply must be housed in a
confined space, forced air cooling may be necessary to keep surrounding
air within acceptable ambient temperature limits. Periodically check the
ventilation grille and clean as necessary.
ELECTRICAL CONNECTIONS
When making the initial electrical connections, make sure the power is
disconnected and follow these precautions.
1. Do not strain or kink the cables. When going around corners, allow as wide
a bend as possible. Do not run the cables parallel to any power line within
a distance of less than 1 foot (305mm).
2. To prevent the possibility of an electrical shock, ensure that the power
supply line cord is properly grounded. Also make sure that the voltage
rating of the electrical power source matches the power supply
requirement.
3. Check with your electrician if you have any wiring questions.
The line cord of the
controller/power supply is
equipped with a 3-prong,
grounding plug. Do not,
under any circumstances,
remove the ground prong.
The plug must be plugged
into a mating 3-prong,
grounding type outlet.
NOTE:
If power supply is
to be run continuously, air
cooling of the converter
and horn is required. Use
clean, dry compressed air
filtered down to 5 microns.
NOTE:
Do not plug the
power supply into an
electrical outlet until all
other connections have
been made.
