27.9. DAISY-CHAINING OF OUTPUTS
Daisy chaining (jumping from one power supply output to the next) is allowed as long as the max. current through one
terminal pin does not continuously exceed 20A. If the current is higher, use a separate distribution terminal.

27.10. SERIES OPERATION
The power supply can be put in series to increase the output voltage.
Fig. 27-10 Schematic for series operation Instructions for use in series:
a) It is possible to connect as many units in series as needed,
providing the sum of the output voltage does not exceed
Unit A 150Vdc.
AC b) Warning ! 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.
DC c) For serial operation use power supplies of the same type.
+ d) Earthing of the output is required when the sum of the output
Unit B
Load voltage is above 60Vdc.
AC
+ - e) Keep an installation clearance of 15mm (left/right) between two
power supplies and avoid installing the power supplies on top of
- Earth each other.
DC
Note: Avoid return voltage (e.g. from a decelerating motor or battery)
which is applied to the output terminals.
27.11. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of load, including unlimited capacitive and inductive loads.
