2 Bolt M8x18 micro-encapsulated
3 Toothed lock washer
4 Contact washer (only necessary on one screw, only with painted housing)
5 Nut M8
Attention! To mount the guard grill, only loosen and unscrew the three screws marked in the product drawing.
Translation of the original operating instructions

The other bolts must not be loosened!

Used screws and nuts must be disposed of.
Use the fastening components available from ebm-papst for assembly.
If the housing is painted, the contact washer (4) must also be inserted between the housing and the nut for one screw.
Tighten the bolts to a torque of 20 Nm ± 3 Nm.
If a guard grille other than that specified in the product drawing is installed, the operator must ensure proper installation according to the
ATEX directive.
In particular, it must be ensured that the necessary distance from rotating parts is observed and that static charge that arises is safely
dissipated. If you have any questions, please contact ebm-papst.

DANGER
Risk of explosion due to poorly sealed terminal box.
The terminal box cover, its seal and the contact surface on the
