SubDrive/MonoDrive Connect

WARNING
!
Serious or fatal electrical shock may result from failure to connect the motor, the SubDrive
MonoDrive, metal plumbing, and all other metal near the motor or cable to the power supply ground
terminal using wire no smaller than motor cable wires. To reduce risk of electrical shock, disconnect
power before working on or around the water system. Do not use motor in swimming areas.
NOTE: Ensure that the system is properly grounded all the way to the service entrance panel. Improper
grounding may result in the loss of voltage surge protection and interference filtering.
1. Verify that the power has been shut off at the main breaker.
2. Verify that the dedicated branch circuit for the SubDrive/MonoDrive is equipped with a properly-sized
circuit breaker. (See Table 1, pg. 15 for minimum breaker size.)
3. Use appropriate strain relief or conduit connectors. See below for conduit hole and knockout sizes.
