.
The +24 V outputs for shut-off valves for axes 1 and 2 are short-circuit-proof.
The energy absorbed when inductive loads are disconnected must be limited to
1.7 J by the user (see also Subsection 2.4.2). When the supply polarity is re-
versed, the outputs are not protected against overload.
!
Warning
If the polarity of the 24 V supply is reversed, then the shut-off valves will open
immediately, even if the NC or closed-loop control is not in operation!
