Zebra Instruments VZPRO
"The most common cause of ECM motor failure is damage to the electronics module caused by poorly conditioned voltage."
-
Turn Off the Main Power
-
Disconnect the power connector from the motor.
-
Plug VZPRO into the motor.
-
Ensure VZPRO is only plugged into motor terminal connectors.
-
Plug VZPRO male terminals into the power connector you previously disconnected from the motor.
-
Fill out the sticker and apply it nearby.
Please Note :
The monitoring LEDs indicate the status of each of the two possible power lines into the VZPRO. If your ECM Motor is set up for 120 Volts, only the “L” terminal will be “hot.” The “N” terminal will be neutral, and “G” is ground.
The same applies in a 240-volt motor, except the “N” terminal will be the other leg of 240-volts; no neutral connection is used.
Fits either 120V or 240V motors! While the VZPRO is not warranted nor able, to stop close lightning strikes or the highest surges, its additional protection will often prevent premature motor failure. The green LED monitors the “L” terminal, and the yellow LED monitors the “N” terminal. When an LED is lit, that line is (a) HOT and (b) protected.
Note that motors using 120 Volts will NOT light the yellow LED.
