3.4 Dimensioning
3.4.1 Inspection

The required protection types can be achieved for example by the following measures:
- Use surface-bonding agent between motor flange and adapter plate.
- Use sealing plates between motor flange and adapter plate to seal the through-holes of the
adapter plate.
Sealing plates are available upon request from
WITTENSTEIN alpha GmbH
.
3.5 Weight
The table "Tbl-5" specifies the gearhead dimensions with medium-sized adapter plate. If another
adapter plate is mounted, the actual dimensions can deviate by up to 10%.
3.6 Noise emission
Depending on the gearhead type and product size, the continuous sound pressure level is up to
68 dB(A) .
Erroneous dimensioning and inspection may lead to loss of explosion
protection.
