2.2 Application
The only application the PCC series controllers are designed for is the interface between a solar module
array and SunPumps Sensorless Brushless DC motors.
No other applications or DC power sources are recommended or warrantied unless written
approval is provided by the SunPumps factory.
3.0 Installation and Operation
The following sections are outlined in a step-by-step format to guide you through the installation and
configuration of an SCS series pump and PCC series controller. The procedure for installing the SCS
submersible pump is the same as a standard AC submersible pump. Any licensed pump contractor will be
familiar with the proper installation procedures. The installation and operation should be in accordance
with local regulations, accepted codes of good practice and common sense. This pump should be installed
by a licensed professional pump installer.
Before installing any pump system read all product manuals then review all system components to
become familiar with the physical and electrical layout. Check all equipment for any product damage.
Refer to applicable figure(s) as a guide during the installation. Controller door must be closed during
normal operation.
Warning
Reverse polarity on a panel system capable of producing over 10 amps will result in
non-warrantied product damage. Please check polarity before connecting power to the
controller.
This controller is for SunPumps Sensorless Brushless DC Motors only. Do not use this
controller on Brush-Type motors or Sensor Type Brushless DC motors. Damage to the
controller will result.
3.1 Location
As the majority of system installations vary greatly, only general comments can be made about the
installation location. Prior to installing the system, it is suggested to make a system layout plan. During
the system layout, take into consideration any potential shading of the solar electric modules, wire runs,
