10.5. Electrical Installation (DVN)
DANGER!
Danger of explosion in explosive atmosphere
(only in the event of a fault as it is zone 2)!
• Opening the hood or the housing in an explosive atmosphere is
only allowed in a not energized state!
WARNING!
Risk of injury due to electrical shock!
• Before reaching into the system (except for the Teach-In proce-
dure in a non-explosive atmosphere) switch off the power supply
and secure it to prevent restarting! Observe applicable accident
prevention and safety regulations for electrical equipment!
Risk of injury from improper installation!
• Installation may be carried out by authorized technicians only and
with the appropriate tools!
