3.4 Device-specific hazards
Danger
Explosion hazard
Death, serious injury, and property damage may occur if the device is being used in
a potentially explosive (classified) location and, during operation, an electrical plug
connection is disconnected or the device is exposed to dangerous impacts or other
types of dangerous mechanical shock.

Use the device in the following environments only:
-
Non-hazardous (non-explosive) areas

Potentially explosive atmosphere, Zone 22:
The ground resistance of accessible metal parts must be less than 10
9
ohms.

When used in a potentially explosive atmosphere, Zone 22, the environment has
to be designed to avoid any bunch discharge.

Make sure that the device is not exposed to dangerous impacts and other types
of dangerous mechanical shock.

De-energize the device before disconnecting plug connections.
WARNING
Live parts inside the device
When the device is open, there will be an electric shock hazard if live parts are
touched.

Do not open the device if it is not de-energized.
WARNING
Equipotential bonding currents
Large transient currents between the protective circuits of different devices may
result in fire or in malfunctions due to signal interference.

If necessary, route an equipotential bonding conductor, with a cross-sectional
area that is several times larger than that of the cable shielding, parallel to the
cable.
