Zebra Instruments X13PR
"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 X13PR into the motor.
-
Ensure X13PR is only plugged into motor terminal connectors.
-
Plug X13PR male terminals into the power connector you previously disconnected from the motor.
-
Plug wires in the same order you unplugged: blue to C, black to L, green to G, and white to N. These wires must be plugged into the correct terminals for the X13PR to function correctly.
-
-
Use enclosed heat shrink tubes on connectors for safety, gently heating them to prevent any exposed terminals. Attach the long green wire to a good electrical ground for the best protection. Use ties to keep wires away from the fan.
-
Fill out the sticker and apply it nearby.
Please Note: The monitoring LEDs indicate the status of each of the two possible power lines in the X13PR. If your X-13 motor is set up for 120 volts, only the “L” terminal will be hot; the “N” is neutral, and the “G” is ground.
The same applies to 240-volt motors, except the “N” terminal is the other leg of 240 volts. No neutral connection is used. 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.
