The +24 V outputs for shutoff 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 Section 2.4.2). When the supply polarity is reversed,
the outputs are not protected against overload.
Warning
If the polarity of the 24 V supply is reversed, then the shutoff valves will open
immediately, even if the NC or closed-loop control is not in operation!
