24 VDC Power Supply
The entire supply must come from a 24 VDC safety extra-low voltage
(SELV) (operating voltage, load voltage, relay supply, etc.).
!
Warning
Personal injury or property damage can result.
If you do not connect the 24 VDC power supply to the
VS 710 correctly, components of your programmable
logic controller may be damaged and there is a risk of
personal injury.
The DC load power supply must fulfill the following
requirements:
Only extra-low voltage (DC
60 V) which is isolated
from the supply may be used as the load current power
supply. The protective separation can be achieved in
accordance with the requirements set out in VDE 0100
Part 410 / HD 384-4-41 / IEC 364-4-41 (as functional
extra-low voltage with protective separation), or
VDE 0805 / EN 60950 / IEC 950 (as safety extra-low
voltage (SELV)), or VDE 0106 Part 101.
