Sources of danger
DANGER!
RISK OF INJURY DUE TO ELECTRICAL CURRENT
The cabinet is connected to the local mains supply.
Touching live devices, which may still be energized, can lead to death, burns or
electrical shock.
▸
Ensure the nominal current/voltage/power ratings of the mains supply are
compatible with the system-specific requirements.
▸
Only qualified specialist personnel are permitted to perform electrical work on the
cabinet.
▸
Before working on electrical components, observe the five safety rules:
▸
Disconnect.
▸
Secure against being switched back on.
▸
Ensure that there is no voltage.
▸
Ground and short-circuit.
▸
Cover or enclose live parts in the vicinity.
▸
Never disconnect or remove any protective conductors in the system or in the mains
cable.
WARNING!
RISK OF INJURY DUE TO EQUIPOTENTIAL BONDING CURRENTS
Due to equipotential bonding currents, incorrect earthing can lead to the following
dangers and faults: Voltage is applied to the metal housing, cable fires due to cable
shields heating up, the product and other devices become damaged.
▸
Generate the same ground potential at all grounding points.
▸
Ground the equipotential bonding via the functional ground connection with a low
impedance.
