6 Maintenance
The appropriate regulations concerning maintenance, repair and
testing must be observed. In particular, all parts on which explosion
protection depends must be checked during maintenance.
The transmitter must never be configured inside the hazardous area
via the setup circuit. For safety reasons (protection of Ex-relevant
components), the connection outside the hazardous area may only
be made for the purpose of brief configuration.
