CONNECTIONS

USER INTERFACE CONNECTIONS
• The input and output connection terminals are located at the rear of the pump. To
access it, unplug the pump and remove the signal cover by taking out the Phillips head
screws that secure it in place.
• Prepare the signal cable by removing 3.5" of the outer jacket. Bare 0.25" on the ends
of the signal wires. See cautionary note below on wire approval, shielding, size, etc.
• Loosen the outer nuts on the liquid tight cord grips. Remove rubber plug from the cord grip.
• Insert a sufficient length of signal cable through the cord grip to allow for wiring.
• Make connections as required.
• Adjust signal cable so that the outer jacket is flush with the inside of the cord grip.
Tighten the cord grip nut flush with the cord grip body.
• Replace signal cover, ensuring that the signal wires do not get pinched between the
signal cover and pump body.
• Replace the signal cover screws, using care to find existing threads, and tighten until
the signal cover is evenly and fully tightened down flush.
Failure to properly tighten or secure the cord grip or signal cover may
allow water to enter the pump enclosure, which can cause pump failure, property
damage, or personal injury.
