2. Install wiring system with proper connections to
the motor electrical box.
3. Connect the green ground wire to the ground
screw.
4. For 460V Wiring: Connect wire L1 to T1, L2 to
T2, and L3 to T3, and bridge the other wires, as
shown.

Leak Sensor Wiring
Follow these instructions to wire the Leak Sensor to
a VFD.
NOTE: The leak sensor is designed to operate as
a normally-closed circuit.
1. Turn off power to the VFD.
2. Open the access cover on the VFD.
3. For a Verder VFD, perform the following:
a. Wire one lead to terminal 4 on the rail.
b. Wire a second lead to terminal 13A on the
rail.
c. Close the access cover.
d. Turn on power to the VFD.
e. Go to screen P121.
f. Change the value to 21 and press the Mode
button.
4. For a non-Verder VFD, perform the following:
a. Attach the two leads to the detection circuit
in the VFD.
NOTE: Refer to the VFD manual for proper
connection points.
b. Close the access cover.
c. Turn on power to the VFD.
d. Configure the VFD to monitor the leak sensor
circuit.
5. Refer to the VFD manual for information on how
