2.8.3.2 STO installation with external DA1 supply voltage (24 V DC)
The two connecting leads, from the external power supply and the safety
relay, to pin4 (STO +) and pin3 (STO-) must be twisted. These twisted leads
must be routed in a closed conduit or conduit (eks ) and screened and the
screen braid grounded (PES).
The external control voltage should meet the following specifications:
Pin 3:
Pin 4:
