The busbar protection system REB500 corresponds to the latest practices and guidelines and
complies with the recognized safety rules. Nevertheless, care must always be taken to avoid
danger.
Use the busbar protection system only when it is in perfect working order and in strict accordance
with the operating instructions.
Dangerous situations can arise if the equipment is used improperly, especially if the user changes
the configuration.
Live electrical equipment is in the immediate vicinity of the REB500 system. Before
working on the system, always ensure that it is impossible to come into contact
with, or even close to live parts.
The IEDs of the REB500 system can initiate operation of items of electrical plant
(circuit breakers and disconnectors). Before working on the equipment, always
ensure that unwanted operation is disabled or has no effect on persons or plant.
Strictly observe all safety precautions (interlocks, locks and blocking devices),
especially those issued for the specific station.
Only properly authorized, professionally qualified and correspondingly trained
personnel, who have also read and understood the operating instructions, may
work on the system.
Dangerous voltages can occur on the connectors, even though the auxiliary voltage
has been disconnected.
Non-observance can result in death, personal injury or substantial property
damage.
Only a competent electrician is allowed to carry out the electrical installation.
National and local electrical safety regulations must always be followed.
The frame of the IEDs has to be carefully grounded.
