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 are not SELV any more and can be dangerous.
Such voltages must be installed with a protection against touching.
Earthing of the output is required when the sum of the output voltage is
above 60Vdc.
Avoid return voltage (e.g. from a decelerating motor or battery) which is
applied to the output terminals.
Restrictions:
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 (terminals
on bottom of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

CP10.241 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.

If more than three units are connected in parallel, a fuse or circuit breaker
with a rating of 15A or 16A 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.
Restrictions:
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
(terminals on bottom of the unit) or in any other condition where a derating 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.
