Product overview
Attention
For switch off in the event of a fault do no external sensor power supply
If the design of your installation is such that the power supply voltage Up is switched off in
the event of a fault, you must not power the connected sensors externally, but only through
the EP23x8! Otherwise, when the Up energy is switched off, the EP23x8 can continue to
draw energy from the external sensor power supply, and the outputs will not be switched
off!
