SunPumps PCA 60 & 120 Install Manual

3.0 Installation and Operation
The following sections are outlined in a step-by-step format to guide you through the installation of a PCA
series controller. Before installing any pump system, read all product manuals and 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-warranted product
damage. Please check polarity before connecting power to the controller.
3.1 Location
As the majority of system installations vary greatly, only general comments can be made as to 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 PC-series controller can either be mounted indoors or outdoors. Locate all system equipment as close as
possible to each other. Generally the controller is mounted on the north side of a pole which has solar electric
modules mounted on top of it. 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 aesthetically and electrically.
