Operating conditions for shaft heights 100 to 160
When operating SIMOTICS M-1PH8 motors in Zone 2 or Zone 22 hazardous areas, carefully take
into consideration the following application conditions:
• Provide specific operating instructions for the motors for when they are used in hazardous
areas (see link and documentation in the Intranet/Internet).
• Motor versions for use in hazardous areas are not UL-approved. As a consequence, these
motors do not bear the cUR marking.
