(EMC Directive 2004/108/EC) and concerning electrical equipment for use within specified voltage limits (Low-voltage directive 2006/95/EC). This conformity is the result of tests conducted by ABB in accordance with the product standards EN 50263 and EN 60255-26 for the EMC directive, and with the product standards EN 60255-1 and EN 60255-27 for the low voltage directive.

Safety information 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.
Although warning hazards are related to personal injury, it is necessary to understand that under certain operational conditions, operation of damaged equipment may result in degraded process performance leading to personal injury or death. Therefore, comply fully with all warning and caution notices. Commissioning Manual Distributed busbar protection REB500...
The * character after an input or output signal name in the function block symbol given for a function indicates that the signal must be connected to another function block in the application configuration to achieve a valid application configuration.

Section 2 Commissioning Preconditions It is assumed that the REB500 protection system is already installed and all input and output signals that have been configured are also wired and the optical fiber cables are run and tested. It must also be assumed that the busbars or sections of them are in operation and that circuit-breakers and isolators are in the process of being installed or maintained.
11. Check the binary input signals 12. Check auxiliary contacts on the isolators and circuit-breakers and the “CLOSE” command 13. Check the control signal and alarm circuits 14. Check the tripping circuits 15. Check the stability factor Commissioning Manual Distributed busbar protection REB500...
2.2.3 Comparison with the layout of the primary system In order to operate correctly, the REB500 process image needs to reflect the actual setup of the primary equipment in the substation. It is therefore important to verify the correct engineering at the beginning and make sure that not yet installed parts are masked accordingly.
Check the proper function of every binary optocoupler input by exciting the signal source. The binary inputs can be checked in one of the following ways: · Reading the status on the local HMI Commissioning Manual Distributed busbar protection REB500...

Do not use petrol or cleaning agents containing alcohol. The REB500 includes continuous and comprehensive self-supervision and diagnosis of the software and hardware components. Since the protection functions are implemented and computed in software, they do not require any periodic maintenance.
