Installation Of The Pse; Mounting; Batteries - SLAT SON 24V 12A MS150 Bedienungsanleitung

2.1

Mounting

The charger has to be installed in a 19"rack that complies to Class 3k5 of EN60721-3-3:1995 +A2:1997
and IP30 of EN60529:1991+A1:2000.
2.2

Batteries

The battery temperature sensor must be placed as close to the battery as possible but does'nt need to be in
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 13 mΩ
becomes 20mΩ±10% in 24V and 40mΩ±10% for 48V if the jumper is set on '50'.
Exceeding this threshold is signalled as a battery fault (see chapter 5) 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 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.
The connections and crimping should be realized properly in order to generate as low resistance as
-
possible.
An additional battery fuse will add about 1 to 2 mΩ.
