Tech Tips
- A True-RMS meter is not needed to check input voltage to this motor. Any
standard AC voltmeter analog or digital will work as long as it can read
voltage up to at least 500 volts.
- If the polarity is reversed on the 115v model the motor may still run, but this
should be corrected.
- Always check high voltage between terminals (L) and (N), never ground, to
check for proper high voltage power.
- Always check low (control) voltage between terminals 1-5 and (C), never
ground.
- Standard meter leads test pins are typically larger than the terminals from the
plug connections or wires being checked for voltage. Using thinner test pins
will prevent terminals from being damaged by voltage checks. Below is an
example of a standard meter lead test pin and a thinner one. These test pins
are also available in 90º angle for tight areas. These types of leads (as shown
below) can be purchased from most meter manufacturers. Our leads were
supplied by Test Products International (TPI). For more information on these
leads please visit our website at www.theDealerToolbox.com.
