Installation Guide

4. Route the cable to charge controller #2.
5. Connect the network cable to a network port in charge controller #2.
6. Connect another network cable to charge controller #2, and then route the cable to the
next device in the network.
7. Make sure the factory-supplied network terminators are inserted into the empty
network ports in the devices at the beginning and end of the network.
There should be no empty network ports in any of the charge controllers.
Installing the Battery Temperature Sensor
WARNING
RISK OF BATTERY DAMAGE
Always install and connect the Battery Temperature Sensor (BTS). See the note directly
below.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
NOTE: For all BTS compatible Xanbus-enabled devices in the system, at least one BTS
must be separately installed for each device type associated with a battery.
If there is a group of the same devices forming a multi-unit setup, only one BTS is
required per device type connected to the same battery (same DC association).
See the installation guide of each device for BTS installation instructions.
Installing a BTS is recommended for optimum charging performance and battery life. If a
BTS is not installed and the batteries must operate in hot or cold conditions, manually
adjust the temperature settings to suit the conditions. See “Configuring Battery
Characteristics and Battery Charging” in the Conext MPPT 80 and MPPT 100 Owner's
Guide.
All networked Xanbus devices share battery temperature information. If there are multiple
battery banks and more than one BTS is used within the system, then the highest
reported temperature will be used as the battery temperature for the temperature
compensation value of the battery charge algorithm.
See Figure 9 on page 31 for the location of the BTS port. Dual knockouts on the back and
sides of the charge controller are provided for routing the BTS cable (see Figure 5 on page
28).
NOTE: If the sensor cable is damaged and the wires are shorted, the charge controller
registers a battery over temperature fault condition. If the BTS wires have been cut, the
charge controller assumes that the BTS is not connected. A replacement BTS can be
ordered from the manufacturer (part number 808-0232-02).
To install the BTS:
