PRELIMINARY
23.2. CHARGING OF BATTERIES
The power supply can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VRLA batteries are
needed in series connection.
Instructions for charging batteries:
a) Use only matched batteries when putting 12V types in series.
b) Ensure that the ambient temperature of the power supply stays below 40°C.
c) Use a 10A circuit breaker or a blocking diode between the power supply and the battery.
d) Ensure that the output current of the power supply is below the allowed charging current of the battery.
e) The return current to the power supply is typically 8mA. This return current can discharge the battery when the
power supply is switched off except in case a blocking diode is utilized.
f) Set the output voltage, measured at no load and at the battery end of the cable, very precisely to the end-of-
charge voltage.

23.3. SERIES OPERATION
Devices of the same type can be connected in series for higher output voltages.
It is possible to connect as many units in series as needed, providing the sum of
the output voltage does not exceed 150Vdc. Voltages with a potential above
60Vdc must be installed with a protection against touching.
Avoid return voltage (e.g. from a decelerating motor or battery) which is
applied to the output terminals.
Keep an installation clearance of 15mm (left / right) between two power
supplies and avoid installing the power supplies on top of each other. Do not
use power supplies in series in mounting orientations other than the standard mounting orientation.

Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple devices.
23.4. PARALLEL USE TO INCREASE OUTPUT POWER
Devises can be paralleled to increase the output power. The output voltage
shall be adjusted to the same value (±100mV) with the same load conditions on
all devices, or the devices can be left with the factory settings.
The ambient temperature is not allowed to exceed +40°C.
If more than three devices are connected in parallel, a fuse or circuit breaker
with a rating of 10A is required on each output. Alternatively, a diode or
redundancy module can also be utilized.
Energize all devices at the same time. It also might be necessary to cycle the
input power (turn-off for at least five seconds), if the output was in overload or short circuits and the required output
current is higher than the current of one unit.

Keep an installation clearance of 15mm (left / right) between two devices and avoid installing devices on top of each
other. Do not use devices in parallel in mounting orientations other than the standard mounting orientation or in any
other condition where a reduction of the output current is required (e.g. altitude).
Pay attention that leakage current, EMI, inrush current will increase when using multiple devices.
