lnstalling accessories on splined shafts
Do not use hammers
or
other tools that might damage the gear unit's shafts
or
bearings when
mounting external parts. lnstead, proceed as illustrated in the diagram below:

5.2
-INSTALLING THE ELECTRIC MOTOR
Further to all the precautions indicated above, when installing a standard IEC
72-1
electric motor, the follo-
wing precautions must also be observed:
• Do not force the coupling and do not use inappropriate tools during assembly. Take care not to damage
the flat/cylindrical coupling surfaces.
• Do not force the rotary coupling mechanisms with heavy overhung or thrust loads.
• To facilitate assembly, use a lubricating synthetic oil paste such as Kluberpaste 46 MR
401
or
another pro-
duet with similar properties and application range.
~::::8.8
• Provided all the above checks have been performed and passed and all other instruc-
tions in
this
manual have been
strictly
observed,
an
electric motor with ATEX rating
equal
to
or
greater than that
of
the gear
unit
may be installed, thus forming a gearmotor
which
itself
complies
with
the provisions
of
Directive 94/9/EC.
lf, instead, the assembly
of
the
motor
to the gear
unit
requires actions other than those
prescribed in
this
Manual
or
one
or
more
of
the manual's prescriptions have
not
been
satisfied, the User shall be responsible
for
analysing the risks attendant on
this
particu-
lar
motor/gear
unit
combination. The risk analysis is in any case obligatory
if
the
motor
is powered
by
an
inverter.
Only in
this
way, and
subject
to
self-certification by the assembler, shall the assembly,
including the gear
unit
itself, be compliant with the requirements
of
Directive 94/9/EC.
