T ESTING FOR C ORRECT V OLTAGES
You must test the receptacle for proper voltages before the eddy current brake is
connected to the outlet.
If the voltage readings do not match the following table, DO NOT connect the
brake. You must have a licensed electrician correct the power connection.
Connecting the brake to the incorrect voltage can result in damage to the brake
and will void the brake warranty. Contact Dynojet with any questions.
Using a voltmeter that is capable of measuring AC voltage, measure between the
points listed below and verify that the correct voltages are present.
