4.1 STO Installation for Frequency Converters with Functional Safety Group 1 (STO - Not Upgrada-
ble)
For motor connection, AC mains connection, and control wiring, follow the instructions for safe installation in the documentation
shipped with the drive. All functional safety related wiring must be done on terminal blocks X31 and X32. See
location of the terminals.
If multi-stranded wires are used in the installation, ferrules or other suitable means must be used to prevent a single core from
short-circuiting with adjacent pins. Install the drive in a cabinet rated IP54 or higher as per IEC 60529, or in an equivalent environ-
ment.
