IMpORTANT NOTICE: Read
Safety Instructions before proceed-
ing with any wiring.
Use only stranded copper wire to pump/mo-
tor and ground. The ground wire must be
at least as large as the power supply wires.
Wires should be color coded for ease of
maintenance and troubleshooting.
Install wire and ground according to the
National Electrical Code (NEC), or the
Canadian Electrical Code, as well as all local,
state, and provincial codes.
Disconnect and lockout electrical power be-
fore performing any service or installation.
All splices must be waterproof. If using splice
kits follow manufacturer’s instructions.
Seal all panel connections tightly from gases
or moisture present which may damage elec-
trical components.

MATCH EQuIpMENT TO
pOWER SupplY: It is important
always to match the pump motor voltage, phase,
and HP ratings to your control panel and power
supply. Record the motor nameplate HP, voltage
and phase in the Owner Information table on the
cover page. Make sure that the power supply, mo-
tor nameplate, and panel nameplate data match.
Incorrect voltage or phase can cause fire, motor
and control damage and voids the warranty.

It is important to use the wiring
diagrams furnished in the manual
and to wire all connections as indicated. Please
refer to Figure 1 on page 4 and pages 9-12.
Motor lead Connections: Locate the terminal
block labeled T1, T2, T3 and ground screw.
Connect wires to terminal block and route wires
through one of the knock out ports on the bottom
of the panel. There is room allowed to wire with
service loops to avoid wire strain.
Input power Cable Installation: The main power
cable is connected to the terminal block labeled
L3, L2, and L1. Room is allowed in the panel to
wire with service loops to avoid wire strain.
PaNEl OPERaTION
Operation is with a Hand/Off/Auto (HOA) three-
position switch on the panel cover. The pump may
be started and stopped at the panel cover by set-
ting the switch to the Hand (manual start) or Off
positions. When the three-position switch is in the
Auto position, start and stopping is controlled only
by the wired remote contact or control device.
ChECk ROTaTION
Always verify correct rotation. Correct rotation
is usually indicated on the pump casing. Motor
direction is reversible. Consult pump and motor
manuals for specific instructions.
A full three-phase supply consisting of three indi-
vidual transformers or one three-phase transform-
er is recommended. “Open” delta or wye connec-
tions using only two transformers can be used,
but are more likely to cause poor performance,
overload tripping or early motor failure due to
current unbalance.
Check the current in each of the three motor leads
and calculate the current unbalance as explained
below.
• If the current unbalance is 2% or less, leave
the leads as connected.
