Mounting the motor on the gear unit

If a motor is included, it is already installed (no assembly required).
Note
Observe the safety instructions
• Observe the information and safety instructions of the motor manufacturer.
• Observe the safety and processing instructions for the threadlocker.
Attention
• Coat the four screws (E) with a threadlocker (e.g. Loctite 243). Use screws of strength class 8.8.
• Attach the motor (C) to the adapter plate (D) with the four screws (E). Note that the tightening torque
for the screws should be 90 % (576 Nm) of the yield strength. Tighten the four screws (E) crosswise.
• Tighten the set screw (B) of the socket (A).
• Push the enclosed sealing plug into the mounting hole (I) of the adapter plate (D) up to the end stop.

Procedure:
• Clean all components to ensure they are grease-free and check
the motor and gear unit for damage prior to assembly.
• Mount the motor in vertical direction, if possible.
• If the motor shaft has a feather key, remove it.
Insert a half wedge, if recommended by the
manufacturer.
• Turn the socket (A) until the set screw (B) is accessible via the
mounting hole.
• Push the motor shaft into the socket of the gear unit.
The maximum permitted axial loads must not be
exceeded.
The motor shaft must slide easily. If this is not the case,
the set screw should be loosened further.
For grooved shafts (H) the slot of the spacer sleeve (F)
must be in line with the groove of the motor shaft and at
right angles with the set screw (B).
There must be no gap between the motor (C) and the
adapter plate (D)
