Hot, toxic or corrosive process media
Danger of injury during maintenance work.
When working on the process connection, hot, toxic or corrosive process media could be released.
• As long as the device is under pressure, do not loosen process connections and do not remove any parts that are
pressurized.
•
Before opening or removing the device ensure that process media cannot be released.
Improper connection after maintenance
Danger of explosion in areas subject to explosion hazard.
• Connect the device correctly after maintenance.
• Close the device after maintenance work.
Refer to Chapter "Connecting (Page 18)".
Use of a computer in a hazardous area
If the interface to the computer is used in the hazardous area, there is a danger of explosion.
•
Ensure that the atmosphere is explosion-free (hot work permit).
Improper modification of parameters could influence process safety.
•
Make sure that only authorized personnel may cancel the key locking of devices for safety-related applications.
Danger of burns during maintenance work on parts having surface temperatures exceeding 70 °C (158 °F).
• Take corresponding protective measures, for example by wearing protective gloves.
•
After carrying out maintenance, remount touch protection measures.
Electrostatic-sensitive devices
The device contains electrostatic-
sensitive devices (ESD). ESD can be destroyed by voltages far too low to be detected by
humans. These voltages can occur if you simply touch a component part or the electrical connections of a module without
being electrostatically discharged. The damage to a module caused by overvoltage cannot normally be detected
immediately; it only becomes apparent after a longer period of operating time has elapsed.
Protective measures against the discharge of static electricity:
• Make sure that no power is applied.
•
Before working with modules, make sure that you discharge static from your body, for example by touching a grounded
object.
• Devices and tools used must be free of static charge.
• Hold modules only by their edges.
•
Do not touch connector pins or conductor tracks on a module with the ESD notice.
