2.2. Batteries
The battery temperature sensor must be placed as close to the battery as possible.
Battery wiring instructions
The power supply takes a resistance measurement of the battery mesh every 4 hours. The trigger threshold of the fault is
±10 %
13 mΩ in 24V and 26mΩ
power supply with its associated battery will not have the desired autonomy in the event of a mains outage.
To avoid initiating this fault, please note the following elements:
Use authorized batteries (see chapter 1.2.5).
-
Use battery cables that are as short and large as possible (35 mm² max).
-
For a cross-section of 10 mm², the resistance is 2 mΩ/m.
o
For a cross-section of 16 mm², the resistance is 1.25 mΩ/m.
o
For a cross-section of 25 mm², the resistance is 0.8 mΩ/m.
o
For a cross-section of 35 mm², the resistance is 0.6 mΩ/m.
o
Example: for battery cables (+ and -) 1.5 m in length and with a cross-section of 10 mm², the resistance is 6
mΩ.
Battery cables (+ and -) of 1.5 m in length and cross-section of 25 mm² allow correct operation with all the
recommended batteries.
Position the temperature sensor as close to the battery as possible.
-
The connections and crimping should be given special care.
-
A battery fuse adds 1 to 2 mΩ.
