Sun Pumps PCA-30M1D - Manual (Page 4)

8. Weather resistant enclosure with a hinged door.
9. Rising clamp screw terminal blocks – no fork terminals required.
10. Pre-adjusted pump configuration and power source selection.
11. Remote switch interface – float switch or remote shutdown –Normally Open or Normally
Closed, user selectable.
2.2 Application
The only application the PCA 30M1D series controllers are designed for is the interface between a solar
module array and SunPumps SDS series DC pumps.
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 SDS series pump and PCA series controller. The procedure for installing the SDS
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.
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 will result in non-warrantied product damage. Please check polarity
before connecting power to the controller.
This controller is for SunPumps SDS Series DC Pumps only. Do not use this controller
on Sensorless Brushless DC 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,
wire size, conduit runs, trenching, controller accessibility, tank location, pump head etc. Shading even a
small portion of the array can reduce the output of the entire array and thus reduce or completely stop the
output of the pump. There is no substitute for a good plan!
The PCA-series controller can either be mounted indoors or outdoors. Locate all system equipment as
close as possible to each other. For top of pole mount racks, the controller is usually mounted on the north
side (shaded side) of the mounting pole. The controller must be mounted in a vertical position for proper
cooling and to keep the electronics dry. The pole should be located close to the well (bore hole). This
general physical layout is conducive to clean installation both aesthetically and electrically.
