Assembly of EWA 10–EWA 16 // Power drives

Please note the procedure for mounting the gearbox breather.

  1. You will find the bleed screw (M6 x 10 with 2 mm axial bore) in the rubber gasket under the limit switch cover.
  2. Establish location of bleed screw on illustration, based on installation position.
  3. Replace located screw with bleed screw (M6 x 10 with 2 mm axial bore). Reuse existing copper seal.
  4. Insert replaced screw back in rubber gasket on limit switch compartment.


  • For an active water application (e.g. cleaning with high pressure cleaner) our power drives are not intended (see instructions) and must be sufficiently protected (e.g. by a cover)
  • Please refer to operating instructions for assembly positions and gearbox breather on the EZW 64.

Our EWA power drives all have the protection class IP 55 according to DIN EN 60529.

That means they:

  • Are protected against dust in harmful quantities.
  • Have a complete protection against accidental contact.
  • Are protected against water jets from any angle.

To ensure long-term functional reliability of the drive we therefore generally recommend a cover for the EWA power drives to keep out splash water, jet water or direct sprinkling (see manual).
