Connect the vendor power cord to a grounded 115 Volt AC, 60 Cycle, noise free
polarized power source of not less than 15 Amps. Checking the power source can be
accomplished with an AC Voltmeter in the following manner:
1. Voltage Check
When the AC Voltmeter probes are
connected to the
HOT and NEUTRAL
terminals, the voltmeter should
indicate 110 to 130 volts AC. See
Figure 7.
2. Polarity and Ground Check
When the AC Voltmeter probes are
connected to the
HOT and GROUND
terminals, the voltmeter should
indicate 110 to 130 Volts AC. See
Figure 7.
Figure 7. Electrical Check with Voltmeter
3. Noise Potential Check
When the AC Voltmeter probes are connected to the NEUTRAL and GROUND
terminals, the voltmeter should indicate 0 Volts AC. See Figure 6. Any voltage
reading could cause noise problems in the electronic controller.
4. Amperage Check
At the fuse box or circuit breaker panel, locate the proper circuit and ensure that
the fuse or breaker protecting that circuit is rated at 15 Amps or greater.
In a standard three (3) prong 115 Volt AC wall outlet the GROUND pin is round, the
NEUTRAL pin is rectangular and located clock-wise from the ground pin and the
HOT pin is rectangular and smaller than the neutral pin and located
counterclockwise from the ground pin. See Figure 7.
To correct negative voltage, amperage, polarity, or ground checks, consult a licensed
electrician. To correct a negative noise potential check, install a noise suppressor which
can be obtained from any electrical or electronic supply store or in kit form.
