Danger!

Only standard motors with an adequate ATEX Zone category according to the name
plate may be used. In addition, for ATEX category 2D gear units (see the ATEX labelling
on the last line of the gear unit name plate), the motor must have at least protection
class IP6x.

Only couplings which are approved and labelled for use in explosion hazard areas may
be used. The ATEX labelling must conform to the details of the system and/or machine
design.

The maximum permitted motor weights indicated in the table below must not be exceeded when
attaching the motor to an IEC- / NEMA adapter:
