SENSbus Connection
The unit is equipped with a SENSbus RJ45 port (see Figure 10). This connection is used to interconnect
SENS specific devices.
WARNING:
DO NOT PLUG ETHERNET INTO THIS CONNECTION
A remote accessory may be connected to multiple chargers. In this case, the remote accessory, chargers
or other equipment may be located at the ends of the communications bus. Ensure a terminator is
located at both ends of the communications bus. Communications with connected devices are available
for every device connected on the bus.

Load Share Connection
—
Optional
Multiple chargers may be connected in parallel to provide charger redundancy and increased
charging current. Connect a straight-thru splitter to the SENSbus RJ-45 port on each charger. Place
a factory installed 120-ohm terminator in one of the splitter positions on each charger to ensure a
terminator is located at both ends of the communications bus. Connect a network cable from one
charger to another using another position on each splitter to automatically initiate load sharing
(see Figure 10).
Use of this sharing cable is essential to synchronizing operation of the Dynamic Boost and HELIX
modes and helps ensure that current is shared 10% between chargers. Chargers intended
for load sharing must be configured with the same output settings in order to load share. No
additional user setup is required to enable active current sharing. Two or more chargers
automatically negotiate with each other to determine which charger is designated as the master
unit.

Remote Battery Monitor
—
Optional
The optional remote battery monitor accessory provides the ability to monitor battery
temperature and ambient temperature. Future options include battery voltage, battery current,
battery float current, 5V logic inputs and other parameters.
Connect a straight-thru splitter to the SENSbus RJ-45 port on the charger. Place a factory installed
120-ohm terminator in one of the splitter positions. Connect the remote battery monitor to the
charger using a network cable connected to the SENSbus RJ-45 port splitter. Place another 120-
