Maintenance, service Operating Instructions ProVicom
7 Maintenance, service
Because the transmission of the devices remains reliable and stable over long periods of time,
regular adjustments are not required.
•Only original parts provided by the manufacturer must be used.
•Fuses may only be replaced by equivalent fuse types.
System maintenance should focus on the following:
a. Seal wear
b. Monitor damage
c. All screws are tightened fast
d. All cables and lines are properly connected and undamaged
)Note:
Associated equipment is subject to maintenance, service and testing according to
guidelines 1999/92/EC, IEC 60079-19 and EN 60079-17 as well as EN 50281-1-2
(Zone 22) !
7.1 Servicing
In accordance with IEC 60079-19 and EN 60079-17, operators of electric plants in hazardous
areas are obliged to have them serviced by qualified electricians.
8 Troubleshooting
Devices operated in hazardous areas must not be modified. Repairs may only be carried out by
qualified, authorized staff specially trained for this purpose.
)Repairs may only be carried out by specially trained staff who are familiar with all basic
conditions of the applicable user regulations and – if requested – have been authorized by
