DANGER
!
Risk of fatal injury due to the formation of an
explosive atmosphere.
Incorrect installation, operation or mainte-
nance of the i/p converter in potentially ex-
plosive atmospheres may lead to ignition of
the atmosphere and cause death.
− The following regulations apply to installa-
tion in hazardous areas: EN 60079-14
(VDE 0165, Part 1).
− Installation, operation or maintenance of
the i/p converter must only performed by
personnel who has undergone special
training or instructions or who is autho-
rized to work on explosion-protected de-
vices in hazardous areas.
The i/p converter requires no maintenance.
Î See section 8 for troubleshooting.
7.1 Servicing explosion-pro-
tected 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 ac-
cording to explosion protection require-
ments, has issued an inspection certificate,
or given the device a mark of conformity.
Inspection by a qualified inspector is not re-
quired if SAMSON performs a routine test
on the device before putting it back into op-
eration. Document the passing of the routine
EB 6111 EN
test by attaching a mark of conformity to the
device.
Replace explosion-protected components on-
ly with original, routine-tested components
by the manufacturer.
Devices that have already been used outside
hazardous areas and are intended for future
use inside hazardous areas must comply
with the safety requirements placed on ser-
viced devices. Before being operated inside
hazardous areas, test the devices according
to the specifications for servicing explo-
sion-protected devices.
