The Locations Electrical Supply
If this machine has a service cord that ends in a 3-pin connector. The wall receptacle you
plug the machine into must be properly polarized and grounded. Operating your machine
from an improperly connected power source will VOID THE WARRANTY. The wall
receptacle must be able to supply a constant 120 volts at 60Hertz. The receptacle should
be protected by a 15 amp circuit breaker or fuse. The machine should have its own
electrical circuit. Perform checks on the power source as follows: (See image below)
1. Voltage Check
When placed across the
HOT
and
NEUTRAL
terminals, a volt-ohmmeter should indicate 110-
130 volts AC.
2. Polarity Check
When placed across the
HOT
and
GROUND
terminals, a volt-ohmmeter should indicate 110-130
volts AC.
3. Noise Potential Check
When placed across the
NEUTRAL
and
GROUND
terminals, a volt-ohmmeter should indicate
no more than .5 volts AC. Readings greater than .5 volts AC indicate a poor grounding condition
that could result in noise problems for the electronic circuitry.
If you are hard wiring the changer the same checks should be performed on the supply line going to the
changer. Any deviation from these requirements may result in unreliable performance from your machine.
Environmental Considerations
Advance consideration should be given to the environmental conditions (temperature, dirt
and moisture extremes) the machine will be exposed to. A
base machine
model is
intended for use in locations where moderate temperatures are encountered and the
machine has minimal exposure to the elements. A typical location where a
base model
would be used is one where the machine is located inside a building. If extended
environmental conditions exist, the machine should be equipped with the additional
ancillary items required to ensure proper performance.
