3.1.21.1.3 Installation
Block Diagram:
To secure from the battery with a fuse with low resistance.
Batteries:
The battery temperature sensor must be placed as close to the battery as possible without being in
physical contact with it. For example, it may be fixed on the battery cables by mean of the two tire
wraps fitted.
Battery wiring instructions:
The power supply takes a resistance measurement of the battery including connections every 4
hours.
The trigger threshold of the fault is 50 mW ±10 %.
Exceeding this threshold is signalled as a battery fault and means that the power supply with its
associated battery will not have the required back-up duration in case of mains power cut.
To avoid initiating this fault, please rad the following elements:
Use batteries with a capacity of 24 to 114 Ah.
Use authorized batteries.
Use battery cables that are as short and large as possible (16 mm² max).
o For a cross-section of 10 mm², the resistance is 2 mW/m.
o For a cross-section of 16 mm², the resistance is 1.25 mW/m.
Example: The resistance is 6 mW for the battery cables (+ and -) 1.5 m in length and with a cross-
section of 10 mm².
