Use of the gear unit exclusively for the application that it 
was designed for.

No modifications to the gear unit by the customer.

Use of the gear unit only in the zone subject to explosion 
hazard that corresponds to the identification on the ATEX 
nameplate.

Use of the gear unit in the surrounding temperature range 
Ta that is specified on the ATEX nameplate.

The maximum thickness of the dust deposit on the gear 
unit may not be more than 5 mm according to EN 50281-
2-1.

No overload of the gear unit with regard to the maximum 
permitted speeds and torques that are specified in the or-
der confirmation.

Compliance with the inspection and maintenance inter-
vals.

Observe these operation instructions.

WARNING!

Unintended use of the gear unit can lead to explosions

Safety information

WARNING!

Failure to comply with these operating instructions can 
cause ignition sources when using the gear unit in areas 
subject to explosion hazard and lead to explosions that 
can cause serious injuries or even death.

Comply with the instructions in these operating instruc-
tions!

Also follow the applicable national, local and system-specific 
requirements.

CAUTION!

Burns!

The surface temperature of the gear unit can significantly ex-
ceed 65° C in operation!

Allow the gear unit to cool down sufficiently before touch-
ing it or wear protective gloves.

2.1 Ignition hazard and protective mea-

sures

The following is an overview of ignition hazards that can arise 
when  operating  the  gear  unit  and  protective  measures  that 
are described in these operating instructions.

Ignition hazard: hot surfaces

Possible causes: increased friction due to improper assem-
bly, wear, overload or leaks.
Protective measures:

Compliance  with  the  maximum  permitted  torques  and 
speeds

Limitation of the motor current

Control before commissioning

Measurement  of  the  maximum  surface  temperature 
during commissioning

Regular inspection and maintenance

Ignition hazard: mechanically generated sparks

Possible causes: improper assembly of leaks

Control before commissioning

Regular inspection and maintenance

Ignition hazard: electrostatic discharge

Possible causes: friction processes, potential differences be-
tween components

Exclusive use of components with ATEX approval

Earth the gear unit housing

2.2 Personnel requirements

All work on the electrical equipment of the drive units must be 
performed by qualified electricians. Installation, maintenance 
and repairs of mechanical parts must be performed by fitters, 
industrial  mechanics  or  persons  with  comparable  qualifica-
tions.
