Check the cable entrance for:
· check for proper fit in the connection box lid using a torque wrench (for
nominal values, see table below). tighten if necessary.
Part Torque (nominal value)
Screwed connection M30 x 1.5
110 Nm ± 10%

· Check for seal. It must be ensured that no liquid enters the interior of
the motor.
Bearing
The bearings have a nominal lifetime of L10h = 30,000 h according to DIN
ISO 281, Edition 1990 if the permitted radial and axial forces are not
exceeded (see Section 12.6). Already insignificant overload of the
bearings affects negatively the bearing lifespan.
The motor bearings should be replaced if:
· the nominal bearing lifetime has been attained,
· running noises occur
Note: We recommend that the bearing be replaced by the Rexroth
Indramat service department.
Connecting cables
Check connecting cables for damage in regular intervals; replace if
necessary.
Check any optional power guide chains (drag chains) that may be present
for defects.
DANGER
Death by electrocution possible due to live
parts with more than 50V!
Þ Do not make any temporary repairs to connecting
cables. If there is even only a small defect in the
cable sleeve, the system must be shut down
immediately and the cable replaced.
Check and, if necessary, replace the grounded conductor connection at
regular intervals for proper condition and tight fit.
