NOTICE
Damage caused by liquid in the case of vertical installation with the shaft extension facing
upwards
If the shaft extension has been installed facing upwards (IM V3), it must be ensured that no
liquid (water, drilling or cooling emulsion, etc.) can accumulate at the upper bearing, as this
can damage the drive.
● If the drive is exposed to the influence of liquid, protect it in mounting position IM V3 using
a cover.
Some of the motor power loss is dissipated through the flange when the S120M is connected
to the mounting surface.
Flange mounting
● Ensure that the flange mounting is evenly distributed.
● When tightening the fixing screws avoid any uneven stressing.
● Use the hexagon socket head cap screws (with a minimum property class of 8.8)
● Note the tightening torques of the fixing screws for the motor flange (see the following table):

Non-thermally insulated mounting
For the specified motor data, the following mounting conditions apply:

Shaft heights 36 and 48 120 x 100 x 40 0.012
SH 63 450 x 370 x 30 0.17
For larger mounting surfaces, the heat dissipation conditions improve.
Mounting with additional mounted components
● Holding brake (integrated in the S120M). No additional torque reduction required.
