WARNING
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.
•
WARNING
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)".
WARNING
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).
•
CAUTION
Releasing key lock
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.
•
CAUTION
Hot surfaces
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.
•
NOTICE
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.
