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.
Only use the busbar protection system when it is in perfect working order and in strict
accordance with these 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 isolators). Before working on the equipment, always
ensure that unwanted operation is inhibited 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.
