The PDS33 solar pump controller’s input power terminal may be switched
manually to a backup AC power source.
Note: Depending on the model number, PDS33 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 from each other to
prevent switching on together resulting the solar PV and the generator being
connected to the solar PDS33 solar pump controller simultaneously! Please check
if the design is in accordance with all applicable national and local electrical codes.
