Load Share Termination
For proper load share operation, a 120-ohm terminator is required at the ends of the bus.
Termination is provided with the charger using the already installed terminator plug (see Figures
11-12).

Remote Alarm/Communications Panel Accessory Connection—
Optional
The optional remote alarm/communications panel accessory provides the ability to adjust and
communicate with multiple chargers using one external device. The remote panel accessory may be
configured with different alarm relay assignments than the alarm relays native to the charger. Connect
remote accessories to the charger using a network cable connected to the SENSbus RJ-45 port. Two
SENSbus RJ-45 ports are provided on the inside panel between the AC and DC connections (see Figures
11-12). Connect a network cable from the remote accessory to one port and leave the factory installed
120-ohm terminator in the second port. Connect the other end of the network cable to the RJ-45
splitter connected to the RJ-45 port on the remote accessory circuit board.
For proper operation, a 120-ohm terminator is required at both ends of the communications bus.
Remote accessories are provided with a terminator installed in the 2-position RJ-45 splitter connected
to the RJ-45 port located on the remote accessory circuit board. Remove the terminator on the splitter
only if the remote accessory is not at the end of the communications bus.
The 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.

Connect Battery/Outputs
Ensure wiring is correctly connected between charger and battery and/or additional outputs for chargers
equipped with multiple outputs. Close any system battery disconnect, if used, to connect batteries to the
charger.
7.2.
Verify Configuration
Refer to the label on the inside lower cover for factory configured output voltage, battery type and
configuration code (see Figure 5). Values for each output are displayed separately for multiple output
chargers. Review and adjust charger configuration using the front panel keypad or the SENS Setup Utility
if factory configured settings require modification. See section
9.10
for additional details on keypad
navigation.
7.2.1.
Output/Battery Voltage
Verify that battery voltage (for applications with batteries) matches charger output voltage.
Charger output voltage is displayed on the label on the inside lower cover.
7.2.2.
Battery Types
Adjusting battery types using the front panel keypad requires advanced security access. Change
“UI Access Control” to “Advanced” in the “Service Tools” menu for access.
