13.1 

Servicing explosion-

protected devices

If a part of the device on which the explosion 
protection is based needs to be serviced, the 
device must not be put back into operation 

until a qualified inspector has assessed it 

according to explosion protection 
requirements, has issued an inspection 

certificate or given the device a mark of 
conformity. Inspection by a qualified 

inspector is not required if the manufacturer 
performs a routine test on the device before 
putting it back into operation and the 
passing of the routine test is documented by 
attaching a mark of conformity to the device.

Inspection by a qualified inspector is not re

-

quired if the manufacturer performs a rou-
tine test on the device before putting it back 
into operation and the passing of the routine 
test is documented by attaching a mark of 
conformity to the device.

 

Î

Retain testing and servicing documents 

as well as certificates issued by the man

-

ufacturer or inspector together with other 
safety-relevant documents for the device 
or plant.

Replace explosion-protected components 
only with original, routine-tested components 
by the manufacturer.
Devices that have already been operated 

outside hazardous areas and are intended 
for future use inside hazardous areas must 

comply with the safety requirements placed 
on serviced devices. Before being operated 

inside hazardous areas, test the devices ac

-

cording to the specifications for servicing ex

-

plosion-protected devices.

Repair of flameproof gaps

A repair of flameproof gaps is not permitted. 

If a corresponding gap is damaged, the de-
vice must be replaced.

Maintenance, calibration and work on 

equipment

Observe the maximum permissible values 

specified in the certificates for intrinsically 

safe circuits to ensure that components rele-
vant to explosion protection are not dam-
aged.
