Sun Pumps MTR BLM-SB-073S-60 - Manual (Page 5)

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.
