The inverters with this option are equipped with an additional board (SRB2) that contains 2 safety relays and
an interconnection cable with the power circuit.
Figure 7.1 shows the location of the SRB2 board and the location of the connector XC25 (used for the connection

DANGER!
The activation of the Safety Stop, i.e., disconnection of the 24 Vdc power supply from the safety relay
coil (XC25: 1(+) and 2(-); XC25:3(+) and 4(-)) does not guarantee the electrical safety of the motor
terminals (they are not isolated from the power supply in this condition).
