6: POWER SUPPLY AND WIRING
Power Supply
The 1151AB2 Controller requires a single
DANGER
phase power supply of 115 volts +/– 15%.
Hazardous
The 1AB2 and 2AB2 Controllers require
voltage
a single phase power supply of 230 volts +/– 15%. The
single phase power supply shall be a dedicated circuit
with branch circuit protection provided by fuses only.
A dedicated circuit means no other appliances use the
same circuit! The output power from the motor controller
is three-phase, variable frequency and variable voltage.
Maximum output voltage and frequency are line input
voltage and 60 Hz, respectively. Low supply voltage will
reduce pump performance.
NOTE: Installation and maintenance MUST be per-
formed by properly trained and qualified personnel.
Always follow the National Electric Code or Canadian
Electric Code, as well as all local, state and provincial
codes when wiring the system.
Wire and Conduit
Do not use wire smaller than 14 AWG. Use of
Metal Conduit with Metal Conduit Connectors is
recommended for all electrical connections.
Output Power Connections
Connect the motor leads for 230 volt or 208
DANGER
volt operation using the nameplate as a
Hazardous
voltage reference. Connect the output power leads
from the controller to the 3 motor leads in the conduit
box on the motor. Connect the ground (green) output
power lead to the ground screw in the conduit box on
the motor. This step is performed in its entirety at the
factory for complete systems. See diagram 4 for details.
NOTE: If the pump has more than 50 feet of wire from
the controller, consult factory for selection of an output
load filter (load reactor).
Connecting Input Power
Connect the input power leads supplied
DANGER
with the controller to a circuit capable of
Hazardous
delivering not more than 5000 symmetrical
voltage
amps with a branch circuit overcurrent
protective devices and two pole disconnect. Connect the
green ground lead to service entrance ground. Be sure
to use Metal Conduit with Metal Conduit Connectors for
electrical connections.

The controller has a high leakage current

to ground. The terminals marked "GND"
Hazardous
voltage in the controller must be connected to the
safety ground from the electrical service entrance. Failure
to properly ground the controller or motor will create an
electrical shock hazard.
NOTE: Do not use GFCI protection with this controller.
Nuisance tripping will result.

voltage power is turned off. Wait 5 minutes after
disconnecting power before opening controller access
cover as there is a severe shock hazard.
Setting the Motor Overload Switches
When the unit is powered, the Motor Over-
DANGER
load Setting Switches are at a high voltage
Hazardous
potential. DO NOT touch the Motor Over-
voltage
load Setting Switches while the power is on.
The Motor Overload Setting Switches adjust the level of
motor overload current protection needed to protect
the motor from damage due to overcurrent conditions.
Turn the circuit breaker and disconnect switch to the off
position, and wait 5 minutes. Remove controller access
cover. On the inside of the access cover is the Motor
Overload Setting table. See Diagram 6 for details. This table
shows the switch setting for the desired Motor Overload
Setting. Read the Service Factor Amps off the motor
nameplate. Use the Motor Overload Setting table to
match the Service Factor Amps (SF Amps) of the motor
to the correct switch setting. See Diagram 5 for details. Set
the Motor Overload Switches according to the correct
combination on the table. If the Service Factor Amps
of the motor do not match any of the Motor Overload
Settings, use the next lowest switch setting. See Diagram 3
for details.
NOTE: The Motor Overload Setting Switches are pre-
set at the factory for complete systems.
Failure to perform this step will result in
CAUTION
loss of Motor Overload Protection and will
void the Motor Warranty. Nuisance Motor Overload Error
tripping or motor damage can occur if these switches are
not set properly.
Setting the Pressure
Turn the circuit breaker and disconnect switch to the off
position, and wait 5 minutes. Remove controller access
cover. Open a faucet in the system and turn the breaker/
disconnect switch to the ON position. The pump will
start and pressure will increase to the factory preset 50
