Fig. 7.4.3A - Attaching a Temperature Sensor to a battery
Connecting a Temperature
Sensor
The temperature sensor should
be connected to the T+ and T-
terminals on the green terminal
block (see p37). The sensor
wire with the stripe goes to
the T– terminal and the sensor
wire without the stripe goes to
T+ terminal. The wires may be
extended if necessary without
affecting the accuracy.
Note: The DTB (bolt-on metal
lug) has no electrical connection
to metal lug housing, so it can be
connected to either the negative
or positive battery terminal.
