Tech Tips
-
The input power can be within ±15% of the nominal 120vac or 240vac. Any
voltage outside of this range should be corrected.
-
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 120v connection the motor may still run, but
this should be corrected.
-
Remember that the 120vac application requires the red jumper and the
240vac application must have this jumper removed. The jumper may not
always be red.
-
Standard meter leads test pins are typically larger than the terminals or
sockets from the plug connections 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
