SAFETY SECTION This Safety Section should be read before commencing any work on the equipment. Health and Safety The information in the Safety Section of the product documentation is intended to ensure that products are properly installed and handled in order to maintain them in a safe condition.
Page 14: Equipment Operating Conditions
Voltage and current connections should be made using insulated crimp terminations to ensure that terminal block insulation requirements are maintained for safety. To ensure that wires are correctly terminated, the correct crimp terminal and tool for the wire size should be used. Before energising the equipment it must be earthed using the protective earth terminal, or the appropriate termination of the supply plug in the case of plug connected equipment.

Page 77 ALSTOM protective relays are designed for a life in excess of 20 years. MiCOM P341 Interconnection Protection Relays are self-supervising and so require less maintenance than earlier designs of relay. Most problems will result in an alarm so that remedial action can be taken. However, some periodic tests should be done to ensure that the relay is functioning correctly and the external wiring is intact.
Page 78 CHAPTER 3 Commissioning and Page 24/80 Maintenance MiCOM P341 8.2.4 Measurement accuracy If the power system is energised, the values measured by the relay can be compared with known system values to check that they are in the approximate range that is expected.
