23.9. Daisy Chaining of Outputs
Daisy chaining (jumping from one power supply output to the next) is allowed as long as the average output current
through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal block as
shown in Fig. 23-7.

(see notes)
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 no longer SELV 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.
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 and output terminals on the top of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
23.11. Inductive and Capacitive Loads
The unit is designed to supply any kind of load, including unlimited inductive of capacitive loads.
