The rated powers for motors for use in hazardous zones are reduced both in S1 and S6 duty
in relation to the non-explosion protected version (standard version). The deratings are taken
into account in the rating plate data:
Article No. Version Derating
1PH8xxx-1xx1x-xxx1-Z, M03, or M39 Induction, forced ventilation 10%
1PH8xxx-1xx2x-xxx1-Z, M03, or M39 Induction, water cooling 20%
1PH8xxx-2xx1x-xxx1-Z, M03, or M39 Synchronous, forced ventilation 20%
1PH8xxx-2xx2x-xxx1-Z, M03, or M39 Synchronous, water cooling 20%
In hazardous areas of Zone 2 (option M03), for induction motor versions, reduce the
permissible maximum speeds (n
max
):
Article No. Version Maximum speed n
max
1PH810x-1xxxx-xxx1-Z, M03 Induction 4350r/min
1PH813x-1xxxx-xxx1-Z, M03 Induction 3000r/min
1PH816x-1xxxx-xxx1-Z, M03 Induction 2250r/min
The motors with forced ventilation have newly developed separately driven fans for use in
hazardous areas. These are in conformance with the applicable directives and standards. Take
the modi󹪝ed dimensions from dimension drawings (SIEMENS Product Con󹪝gurator).
The supply values for the separately driven fans are speci󹪝ed in the following table:

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 speci󹪝c 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.
