“Risk of electrical shock” Do not remove power supply cord 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
required.
UU
Follow the instructions provided with the panel to wire the system.
UU
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 lead of power cord (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.
Three phase pumps have integral motor overload protection. It is recommended that all
three phase pumps using a motor starting device also 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 electrical 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.
