6. Field Wiring
Do not touch any of the components or wires located in the panel without first removing power to this
panel. Any of these wires may have voltage connected to them.
6.1 Power and Motor
Main power into this system is supplied in the upper right corner inside the panel. This system is powered with
120 or 220 volt AC power, single phase. All power lines are terminated at the disconnect or terminal block
located in the upper right-most corner of the enclosure. Common voltage and the ground wire are terminated
where indicated. Incoming power wiring should not exceed 12 AWG.
Motor power from this system is provided along the bottom of the enclosure at the main terminal blocks. Positive
motor voltage is on terminal 2261 and negative motor voltage is on terminal 2271. These lines should not exceed
14 AWG wires. Shunt wires may also be connected in some applications. If a shunt-wound motor is used,
connect the positive shunt wire to 2241, and the negative shunt wire to 2251.
6.2 External Signals
All external signals will be terminated on the main terminal block located at the bottom of the enclosure.
6.2.1 Inputs (Yellow Terminal Blocks)
• Remote start input, Dry Contact
The Remote Start input will be a normally open (NO) contact closure from the main panel. Two wires should
be provided. Upon closure of the remote contact, the pump will operate. 120 volts will be present at 1291,
and 1321 will be the signal to run the pump. A short circuit between these wires will cause the pump to run
continuously in the Auto mode. These wires should not exceed 14 AWG.
• Remote start input, Powered
The Remote Start input will be a 24VDC or 115VAC signal from the main panel. Both the + (line)
and the common (neutral) signal will need to be provided. Positive/line will connect at terminal 1431, and
common/neutral will connect at terminal 1432. These wires should not exceed 14 AWG.
6.2.2 Outputs (Green Terminal Blocks)
• Motor running output
The Motor Running output will be a normally open contact signal to the main panel. The common signal will
connect to terminal 1261, and active signal will connect at terminal 1262. These wires should not exceed 14
AWG wires.
