Installation of the PSE
2.1
Mounting
Figure 4 : Mounting the PSE
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
Mains
Use a bipolar D curve circuit breaker (4A for 24V version and 6A for 48V version) to connect the power supply to
the mains circuit.
2.3
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
Use a bipolar isolating switch (e.g. isolator or disconnecting switch) by connecting the batteries to the supply.
An additional fuse is also recommended to protect this circuit.
In order to avoid any electrical damage, the cables connecting the batteries must imperatively match with the supply
configuration (100 or 150A) : maximum sheath temperature, cross section, allowed current, maximum voltage.
Operation :
The power supply takes a resistance measurement of the battery including connections every 4 hours.
The trigger threshold of the fault is 16m
10 %
in 24V and 32m
10%
in 48V if the jumper is set on '75', and
becomes 24m
10%
in 24V and 48m
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).
-
Do not exceed the lengths of the table (see appendix page 34 and following)
-
Ensure proper connections and crimpings.
-
An additional battery fuse will add about 1 to 2 m
.
