THREE PHASE WIRING INSTRUCTION
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP
FROM ITS POWER SOURCE BEFORE HANDLING.
“Risk of electrical shock” Do not remove power supply cable and
strain relief or connect conduit directly to the pump.
Installation and checking of electrical circuits and hardware should
be performed by a qualified licensed electrician.
To automatically operate a non-automatic three phase pump, a control panel is

For
automatic three phase pumps see automatic three phase wiring diagram.
Before installing a pump, check the pump rotation to insure that wiring has been
connected properly to power source, and that the green leads of power cable (See
wiring diagram), is connected to a valid ground, momentarily energize the pump,
observing the directions of kick back due to starting torque. Rotation is correct if kick
back is in the opposite direction of rotation arrow on the pump casing. If rotation is not
correct, switching of any two power leads other than ground will provide the proper
rotation.
The KZE pumps include thermal motor sensor switches that are embedded in the motor
windings. The sensor leads are connected to the start circuit on the motor control panel
as shown in the example wiring diagrams. It is recommended that all pumps using a
motor starting device incorporate motor overload protection. Pumps must be installed in
accordance with the National Electrical Code and all applicable local codes and
ordinances. Pumps are not to be installed in locations classified as hazardous in
accordance with National Electrical Code, ANSI/NFPA 70.
Connect pump to a junction box, outlet box, control box, enclosure with a wiring
compartment that meets NEC and local codes. The provision for supply connection
shall reduce the risk of water entry during temporary, limited submersion and shall
comply with the applicable requirements of the Standard for Enclosures for Electrical
Equipment, UL 50, or the standard for Metallic Outlet Boxes, UL 514A, and the standard
for Motor-Operated Water Pumps. UL 778.
