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
