Performance data for gearboxes in explosive atmospheres:
Based on test results, the maximum permissible speeds and torques as well as the data on service
life are reduced in relation to the standard gearbox. The shaft loads are also reduced in relation to
the standard gearbox. See Chapter 10.6 "Technical specifications".
The gearbox can be used in potentially explosive atmosphere group II, zones 1 and
2 as well as group III, zones 21 and 22. The gearbox can be operated in a gas
atmosphere in temperature class T3. In a dust atmosphere, a maximum surface
temperature of 150 °C is possible.
Observe the instructions on the name plate and the appendix on the written
certificate of conformity.
The gearbox is manufactured and certified for use in potentially explosive
atmospheres in compliance with standard DIN EN ISO 80079 and EU Directive 2014/
34/EU.
Strictly observe the restrictions on speeds and torques (see Chapter 10.6
"Technical specifications").
Observe the general safety instructions for explosion protection (see Chapter 2.5
"General safety instructions").
