Structure of warning instructions
Dangers
Possible causes
Protective measures
Hot surfaces
Increased friction and dissipated
power because of wear, improper
assembly, overload or leaks.
Reduce torques and speeds
compared to standard gearboxes
Limit the motor current and
maximum speed of the motor
Maintenance intervals for wear
parts and lubricant according to
maintenance schedule
Check the temperature behavior
and the run-in behavior before
startup
Regular visual and acoustic
inspections
Prohibit certain mounting
positions and conditions
Increased surface temperature
due insulation by dust deposits.
Cleaning regulations according to
maintenance plan
Mechanically
caused sparks
Overload on shafts, moving parts
and connection elements.
Reduce torques and external
loads compared to standard
gearboxes
Limit the motor current of the
motor
Perform maximum load test
before startup
Static electricity
Potential differences between
components, cleaning processes,
insulating layers
Ground the gearbox and the
motor
Tbl-1: Summary of the hazards and protective measures for potentially explosive atmospheres
Warning instructions are situation-specific. They
will be precisely where tasks are described in
which dangers can arise.
The warning instructions in this manual are
designed according to the following pattern:
A
= Safety symbol
(see Chapter 2.6.1 "Safety symbols")
B
= Signal word (see Chapter 2.6.2 "Signal words")
C
= Type and consequence of the danger
D
= Avoiding the danger
