3.11.3.4 Emergency power-off and protective door monitoring without
safety switching devices
With Compax3M, a 2-channel protective door monitoring switch or a 2 channel
emergency power-off switch can be directly connected. The figure below visualizes
an application with 2 channel protective door monitoring switch.
The Compax3M drive modules with Compax3MPxx mains rectifier must be located
in a protected area (IP54 control cabinet). Outside this protected area, the line
guiding to the external switches must be separated channelwise or must be espe-
cially protected (screened).
It is also permitted to use one acknowledgement switch for both servo drives at a
time. In both cases the acknowledgement does only correspond to category B (no
longer category 3), therefore this acknowledgement should not be used if there is
any possibility of stepping in the dangerous area. In this case, an external acknow-
ledgement device must be used.
