Switching to Backup AC Power
The PDS23 solar pump controller’s input power terminal may be switched manually
to a backup AC power source.
Note: Depending on the model number, PDS23 solar pump controllers support
power input either 220VAC single phase, or 380VAC three phase, Please contact
controller manufacturer or authorized agencies for details.
When the system is running on back-up AC power, please check for sufficient DC
primary source power every 30 minutes. If the primary DC power is available, shut
down the controller, switch back to primary power and attempt to run on DC
power supply.
NOTICE :
A DC circuit switch and a generator power switch must be installed, and
these two switches must be mechanically interlocked each other to prevent
switching on together resulting the solar PV and the generator being connected to
the solar PDS23 solar pump controller simultaneously! Please check if the design is
in accordance with all applicable national and local electrical codes.
