If you are not using a

WARNING
TEST max open circuit voltage:
If you are using a
battery system, install a
jumper wire between
terminals 6 and 7.
PV Modules (Solar Panels)
Before connecting the array to the
controller measure the open-
circuit voltage. It must be within a
range of
PS200 : 35-90V DC
PS600 : 75-135V DC
PS1200: 110- 180V DC
PS1800: 110- 180V DC
Float Switch (optional)
Float Switch Kit makes contact on
rise to stop pump.
Connect termins 3 (NO) and 4
(COM) and connect terminals 4
and 5 with jumper wire.
This is an example, using 2-8 X 12V-nominal PV modules. Your system may vary in the
number, voltage, and configuration of PV modules. The system here below is typical for either
a PS200 (2-4 modules in Series) or PS600 (4-6 modules in Series) or PS1200 ( 6-8 modules
in Series) or PS1800 (6-8 modules in series)
