Cleaning and servicing

•
The motors must be grounded via a motor
cable and via a second separate ground con-
ductor with minimum 4 mm² cross section.
Check that the position of the grounded con-
ductor is fixed before commissioning.
•
Use cables with a thermal stability of at least
80°C (176°F).
•
Plug connector: Never connect or disconnect
plug connectors under load!
•
Connect and operate MS2E motors only
with origin connection accessories. Use
ready-made cables by Bosch Rexroth or
with origin connectors ready-made connec-
tion cables. In the case of self-assembled
cables, observe the notes about tensile load
in the section "Special conditions "X"" in
chapter⮫ Chapter 4.4 "Special conditions on
use X" on page 23.
WARNING
Danger of explosion due to exalted tensile load of
connection cables
Adherence of specified limits.
Mechanical fastening of cable ends (e.g. use
cable clamps, ...).
•
The plant manufacturer and operator is
responsible for test and documentation of
the tensile load.
•
Observe the limit values for bearing load. If
necessary, change the bearing according to
⮫ Chapter "Bearing service life " on page
After maintenance and repair work, Bosch
Rexroth always recommends to do a safety and
functionality test on basis of the risk analysis
provided by the customer (e.g. for thermal pro-
tection, holding brake).

Maintenance

10.1 Cleaning and servicing
WARNING
Operations in the vicinity of live parts are
extremely dangerous.
−
Work required on the electric system may
only be carried out by skilled electricians.
Tools for electricians (VDE tools) are abso-
lutely necessary.
−
Isolate (even auxiliary circuits).
−
Secure against reactivation.
−
Ensure de-energization.
−
Ground and short-circuit.
−
Cover or shield any adjacent live parts.
WARNING
Personal and material damage during mainte-
nance work in operation!
−
Never carry out maintenance work on run-
ning machines.
While carrying out maintenance work,
secure the machine such that it cannot
restart or be used by unauthorized persons.
CAUTION
Hot surfaces with temperatures over 60 °C may
cause burns!
41.
−
Allow the motors to cool down prior to com-
mencing work.
Wear safety gloves.
Do not work on hot surfaces.
Motors
Dirt, dust or chips may adversely affect the func-
tionality of the motors and, in extreme cases,
even cause a failure of the motors. Therefore, at
regular intervals (after one year at the latest), you
should clean the surface of the motors in order to
achieve a sufficiently large heat radiation surface.
