The technical specifications in this chapter are supplemental for ATEX systems only. For comprehensive
technical specifications, including maximum pressure rating, maximum flow, etc. please refer to the
standard H1B Technical Information document.
Danfoss does not claim responsibility for the use of the motors in operating conditions not allowed
according to the information shown in this document and the standard H1B Technical Information
document.
Painting or coating can be an electric insulator if a thickness greater than 200 um is applied. The
thickness of the paining of original DPS paint is less than 200 um.

To ensure that the surface temperature will not exceed the allowed value according to the used
temperature class, it is recommended to attach a temperature sensor to the motors in the shown area on
one of the side surfaces near the maximum displacement limiter at the bottom side of the motors.
