Task 7 - Mount the Battery Temperature Sensor

The DC power system is supplied with a battery temperature sensor and standard 8 m (26
feet) long RJ45 cable, already connected to the supervisory module to measure the ambient
air temperature around the batteries. This is required for the temperature compensation
control function.
Step 1 - Connect and route cable
28
Remove the covers from batteries 1 and 4.
1
Check with a voltmeter that the negative terminal of battery 4 is more
2
than 48V negative of the positive terminal of battery 1.
Check all terminal covers are in place.
3
Check that the battery terminal connections are not touching metalwork
and that there is a sufficient gap between the terminals and the rack. Do not
proceed until this has been checked and corrected if necessary.
Repeat the above procedure for the remaining battery shelves to be
1
populated. Work from the bottom to top shelf.
Repeat for additional battery racks if required.
2
Connect the temperature sensor cable supplied to socket XH7 on the
1
I/O board.
If required extend the cable using an RJ45 patch cable and in-line
joiner. Recommended maximum cable length is 20m (65 feet) because of
noise considerations.
Route the temperature sensor cable to the middle battery shelf (in
2
systems with integrated battery shelves) or the middle of an external
battery stand.
Do not run the sensor cable along AC power cables. Interference may
cause false readings.
