T
he upper board has ports for both the
Remote Temperature Sensor (RTS) and the
system display. The system display port is
labeled Remote. The RTS port is labeled
Battery Temp.
If a HUB Communications Manager is in use, it
occupies the inverter’s Remote port. The
system display plugs into the HUB product.
See the Operator’s Manual
for functional information on the RTS.

Additional
Ports
When a HUB Communications Manager occupies the inverter’s Remote
port, the system display connects directly to the HUB’s MATE port.
Inverters connect to communications manager ports 1 and above.
Charge controllers and other devices connect to additional ports after
the last inverter is connected. See Stacking on page 31 for information
on connecting inverters.
The
ON/OFF INV
jumper bridges two pins. This jumper (J3) parallels the
two
Switch INV
terminals on the terminal block. If either set of
connections is closed, the inverter is on. (Although the jumper is
factory-installed to the on position, the inverter is given an off command
before leaving the factory and will initially be off.)
If the Radian is inverting, removing the
jumper will turn it off. To remove the
jumper, use long-nose pliers or a
similar tool.

Once the plastic
ON/OFF INV
jumper
has been removed, the
Switch INV
terminals on the terminal block can be
used to wire a manual on/off switch.
These terminals can also be used to
control an Emergency Power Off (EPO)
device instead of a standard switch.
