Mounting
Note: When installing the module in the rack, the protection rating must comply with fire safety standards EN 54-4/A2:
IP30.
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 %.
50 mΩ
Exceeding this threshold is signalled by a battery fault and means that the 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 batteries with a capacity of 24 to 110 Ah.
-
Use Yuasa, Powersonic brand batteries. If you would like to use another battery brand, please have them
approved.
Use battery cables that are as short and large as possible (16 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
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 16 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.
