Fastening the DCA63.. and DCA80.. motor

Observe the following information when fastening the screws on the motor:

• When fastening, use only the bores on the output end of the motor housing.
• To that end, transfer the bores required for the centering collar of the motor and the pitch circle of the mounting bores onto the mounting plate and drill (see following drawing).
• Secure the drives to a flat surface by using at least 4 screws.
• Use self-tapping screws according to DIN 7500 for fastening. SEW-EURODRIVE recommends screw connections consisting of Taptite 2000^® screws.
• Of the 3 available hole circles, choose the one with the largest diameter whenever possible.
• If you undo and reconnect the screw connection, you can also use metric screws. In this case, SEW-EURODRIVE recommends using threadlocker.
• Self-tapping screws can be screwed in again after being undone. To do so, turn the self-tapping screw contrary of the direction of rotation until the thread sets into place. Then manually screw in the self-tapping screw one turn. Then tighten the self-tapping screw using the specified torque. Impulse screwdrivers or impact screwdrivers must not be used. Manual handheld screwdrivers are only permitted in service cases.
• Adhere to the recommended tightening torques of the retaining screws according to the tables in chapter Determining the screw length.
