WARNING
Electrostatic charge
Danger of explosion in hazardous areas if electrostatic charges develop, for example, when
cleaning plastic surfaces with a dry cloth.
● Prevent electrostatic charging in hazardous areas.
9.3 Maintenance and repair work
The device is maintenance-free. However, a periodic inspection according to pertinent
directives and regulations must be carried out.
An inspection can include, for example, check of:
● Ambient conditions
● Seal integrity of the process connections, cable entries, and cover
● Reliability of power supply, lightning protection, and grounds
WARNING
Maintenance during continued operation in a hazardous area
There is a risk of explosion when carrying out repairs and maintenance on the device in a
hazardous area.
● Isolate the device from power.
- or -
● Ensure that the atmosphere is explosion-free (hot work permit).
WARNING
Humid environment
Risk of electric shock.
● Avoid working on the device when it is energized.
● If working on an energized device is necessary, ensure that the environment is dry.
● Make sure when carrying out cleaning and maintenance work that no moisture penetrates
the inside of the device.
