NOTE!
Inverter Safety Stop function is only one component of the safety control system of a machine
and/or process. When inverter and its Safety Stop function is correctly used and with other safety
components, it’s possible to fulfill the requirements of standard EN 954-1 / ISO 13849-1, Category 3
(machine safety) and IEC/EN 61508, SIL2 (safety control/signaling applied to processes and systems).
Parameter P0029 indicates if the inverter identified the SRB board correctly. See Bit 9 in
for further details.

For XC25 control cabling considers the following:
Use wire gauge from 0.5 mm
2
(20 AWG) to 1.5 mm
2
(14 AWG) and maximum tightening torque of maximum
0.50 N.m (4.50 lbf.in).
Use shielded cables connected to ground only on inverter side. Use the provided metallic pieces as shown on
.
Run the cables separated from the remaining circuits (power, 110 V / 220 Vac control, etc.).
