EC 911 / EC 912
The workmanship of the installation of the intrinsically
safe circuits has to comply with the installation regula-
tions in accordance with EN 60079-14.
When other intrinsically safe field devices are intercon-
nected with the intrinsically safe circuits of the associat-
ed EC 900 devices, the relevant maximum values of the
22
field devices and associated devices have to be observed
with regard to explosion protection.
The EC certificate of conformity and/or EC type examina-
tion certificate have to be observed. It is of particular
importance that the "Particular conditions" possibly con-
tained therein are complied with.

Commissioning

Installation and commissioning are to be carried out by specially trained and qualified staff only.
For cabling, the applicable standards have to be observed.
The plug is to be installed properly on the appropriate mating socket and secured mechanically.
Operation is only permitted if the casing is completely closed.

Servicing, maintenance and troubleshooting

Devices which are operated in conjunction with areas subject to explosion hazards must not be
changed. Any repairs of the equipment may only be carried out by specially trained and authorized
qualified staff from RMG Messtechnik.

Changing the battery

When changing the battery, only the specially manufactured main batteries from RMG Messtechnik
may be used. These must not be changed when the equipment is in operation. The same conditions
apply for the B1 back-up battery (button cell) which powers the clock.

Removal

When removing the device, make sure that the sensor cable does not come into contact with other
live parts.
Make sure that you take appropriate safety precautions.
