WARNING
● Install the motors only when they are de-energized and not connected
electrically.
● Use suitable lifting equipment and protective equipment and wear pro‐
tective clothing during transport.
● Do not lift or move the motor by the fan unit.
● Please observe the safety-related guidelines in the preceding chapters
and the transport-related guidelines for motors in chapter
"Handling and transport" on page
Carry out all work steps with particular care. This minimizes the risk of acci‐
dents and damage.
Some of the MAD/MAF motors of frame size 130 and higher fea‐
ture additional threaded holes on their longitudinal sides where
eyelets can be inserted (for details, see dimension drawing). Ad‐
ditional eyelets can simplify the transport and handling of the mo‐
tors.
To attach the motors properly and safely to the machine, Bosch Rexroth rec‐
ommends the following screws and washers for attachment.
● Motor frame size 100
– Pan head screw DIN EN ISO 4762 - M12 x ... - 8.8
and
– Washer DIN EN ISO 28738
● Motor size 130 ... 225
– Hexagon screws DIN EN ISO 4014 - M... x ... - 8.8
or
– Pan head screw DIN EN ISO 4762 - M... x ... - 8.8
and
– Washer DIN EN ISO 7090 - ... - 200 HV
If screws and washers other than the recommended ones are
used, the property class of the screws and the hardness class of
the washers have to be equivalent in order to ensure that the re‐
quired tightening torques are transmitted (see
ing holes and tightening torque of the screws" on page
