22.9. Charging Batteries
The power supply can be used to charge lead-acid or maintenance free batteries. (Four 12V batteries in series)
Instructions for charging batteries:
a)
Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge
voltage.
End-of-charge voltage
55.6V
55.0V
54.3V
53.6V
Battery temperature
10°C
20°C
30°C
40°C
b)
Use a 15A or 16A circuit breaker (or blocking diode) between the power supply and the battery.
c)
Ensure that the output current of the power supply is below the allowed charging current of the battery.
d)
Use only matched batteries when putting 12V types in series.
e)
The return current to the power supply (battery discharge current) is typ. 7mA when the power supply is switched
off (except if using a blocking diode).

The power supply can also be used on two phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying
voltage is below 240V

22.11. Use in a Tightly Sealed Enclosure
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher
than outside. In such situations, the inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The power supply is placed in the middle of the box, no other heat producing items are inside the box
Enclosure:
Rittal Typ IP66 Box PK 9522 100, plastic, 254x180x165mm
Load:
48V,

Temperature inside enclosure:
53.3°C (in the middle of the right side of the power supply with a distance of 2cm)
Temperature outside enclosure: 25.3°C
Temperature rise:
28.0K
