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.
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.
Do not plug the power
supply into an electrical
outlet until all other
connections have been
made.
