Installation of your equipment
2.1.
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
50 m
Ω
±
10 %.
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).
o
For a cross-section of 10 mm², the resistance is 2 m
Ω
/m.
o
For a cross-section of 16 mm², the resistance is 1.25 m
Ω
/m.
Example: for battery cables (+ and -) 1.5 m in length and with a cross-section of 10 mm², the resistance is 6
m
Ω
.
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 m
Ω
.
