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 compati-
ble 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.
Note
Before removing the power supply unit, note the assignment of the cables to the connec-
tions.
