23.2. SERIES OPERATION
Power supplies 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 (input terminals on bottom of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
23.3. PARALLEL USE TO INCREASE OUTPUT POWER
Power supplies can be paralleled to increase the output power. The output
voltage of all power supplies shall be adjusted to the same value (±100mV)
with the same load conditions on all units, or the units can be left with the
factory settings. There is no feature included which balances the load current
between the power supplies. Usually the power supply with the higher
adjusted output voltage draws current until it goes into current limitation. This
means no harm to this power supply as long as the ambient temperature stays
below 40°C for AC 120-240V mains and below 35°C for AC 100V mains.

Output
If more than three units 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 units at the same time to avoid the overload Hiccup
PLUS
mode. It also might be necessary to cycle the input
power (turn-off for at least five seconds), if the output was in Hiccup
PLUS
mode due to 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 power supplies and avoid installing the power
supplies on top of each other.
Do not use power supplies in parallel in mounting orientations other than the standard mounting orientation (input
terminals on bottom of the unit) 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, harmonics will increase when using multiple power supplies.
