5.4 Electrical Installation-Terminals
Power IN For PV-direct systems, a two-pole discon-
nect switch may be installed between the solar array
and the controller. Switch it off to prevent shock and arc
burn hazard during installation and maintenance, or if
the system will be shut down for the season. For
battery systems a 30 Amp slow blow fuse must be
installed between the controller and the battery.
Ground Connect the ground wire to the ground
connection in the controller. Grounding helps to prevent
shock hazard if there is a fault in the motor.

wire) cable between the controller and the motor. The
three wires L1, L2 and L3 carry power. The fourth wire
carries ground. To reverse direction of rotation reverse
any two wires.

to each terminal. If dry run protection is not needed,
short cut these two terminals.
No. 3, 4 and 5 Connect any kind of external switch (NO
or NC type) for remote control of the controller. In case
no switch is used the terminals No. 4 and 5 have to be
connected with a short cable (factory setting). In case a
NO-switch is used (connected to the terminals No. 3
and 4) the short cable (connecting the terminals No. 4
and 5) must remain installed.
No. 6 and 7 Connect these two terminals to switch the
controller to battery mode. The motor will be switched
OFF by the controller if the input voltage is below 11 V
for a 12 V battery system and 22 V for a 24 V battery
system in order to protect the battery. If the battery
voltage increases to 13 or 26 V the motor will be
switched ON automatically.
