Introduction
1 1
For compliance with the European Agreement concerning
International Carriage of Dangerous Goods by Inland
Waterways (ADN), refer to chapter ADN-compliant Instal-
lation in the VLT
The frequency converter complies with UL 508C thermal
memory retention requirements. For more information,
refer to chapter Motor Thermal Protection in the VLT
Drive FC 280 Design Guide.
Applied standards and compliance for STO
Using STO on terminals 37 and 38 requires fulfillment of all
provisions for safety including relevant laws, regulations,
and guidelines. The integrated STO function complies with
