The motors fulfill the explosion requirements with the Directive 2014/34/EU for the category shown on the name plate. The OMS motors have an identifying name plate. The name plate provides essential information and specification for correct and safe use. This identifying plate has to be maintained so that the data can be clearly read; consequently, a periodic cleaning of the plate is required.

The operating principle of the motor is based on an internal gear design, consisting of a fixed external gear reaching against an internal gear through which the output torque and speed are transmitted. The distributor valve in OMS motors is of the disc valve design which is driven synchronously by the internal gear through a cardan shaft ensuring that the individual chambers of the motor are filled and emptied precisely.
Oil temperature Maximum oil temperature depends on the requested ATEX class needed. See Maximum surface temperature for OMS on page 8. Under normal operating conditions it is recommended to keep the temperature in the range of 30 °C [86 °F] to 60 °C [140 °F].

For installation in zones 21 and 22 the user has to adopt a scheduled periodic clearing plan of the motor surfaces and recesses to prevent more than 5mm thickness of dust deposits. Service and repair of OMS motors In case a service or repair intervention on the motor is required, it has to be performed according to the information shown in the respective Repair Instructions.
