Junction Box (Controller Input) Wiring

WARNING TEST THE VOLTAGE before
connecting power to the controller. Voltage
(open circuit) must not exceed 100V for
PS200-, 150V for PS600 and 200V for
PS1200 systems. (Even in cloudy weather,
the open circuit voltage will be near maxi-
mum.)
WARNING Do not apply a direct connection
or an amp meter between + and – when the
controller is connected. A short circuit
here will cause a strong discharge.
WARNING SOLAR-DIRECT systems only —
Do not connect any electrical load to the
solar array if it is not part of the LORENTZ
Pump system. Connection of a battery
charger, active solar tracker controller, electric
fence charger, or other load simultaneously
with LORENTZ PS systems may "confuse"
the controller and prevent proper operation.

System Diagram For solar-direct systems,
refer to the System Diagram at the end of this
manual.
Ground connections The two ground
terminals in the junction box are bonded
together and are also bonded to the metallic
enclosures of both the junction box and the
controller. See Section 5.2
POWER IN Ensure that the solar array
DISCONNECT SWITCH (or battery fuse or
circuit breaker)- is OFF. Connect the power
from the solar array to the input terminals in
the junction box. Observe polarity. If your
wires are not clearly marked +/–, test them
using a DC voltmeter or multitester.
PUMP See Section 5.8.
Low Water Probe See Section 5.9
Float Switch See Section 5.10, Automatic
Control for Full-Tank Shutoff. A connection is
made at the factory between terminals 4 and
5. If you are NOT using a float switch, leave
this connection in place.
CAUTION If you
are not using a
low-water probe,
connect a small
wire between
terminals 1 and 2.
