    Safety Section P44x/EN SS/H11 (SS) - 3 STANDARD SAFETY STATEMENTS AND EXTERNAL LABEL INFORMATION FOR ALSTOM GRID EQUIPMENT INTRODUCTION This Safety Section and the relevant equipment documentation provide full information on safe handling, commissioning and testing of this equipment. This Safety Section also includes reference to typical equipment label markings.
  • Page 10: Symbols

    P44x/EN SS/H11 Safety Section (SS) - 4 SYMBOLS AND LABELS ON THE EQUIPMENT For safety reasons the following symbols which may be used on the equipment or referred to in the equipment documentation, should be understood before it is installed or commissioned.
  • Page 11 Safety Section P44x/EN SS/H11 (SS) - 5 Watchdog (self-monitoring) contacts are provided in numerical relays to indicate the health of the device. Alstom Grid strongly recommends that these contacts are hardwired into the substation's automation system, for alarm purposes. To ensure that wires are correctly terminated the correct crimp terminal and tool for the wire size should be used.
  • Page 12 P44x/EN SS/H11 Safety Section (SS) - 6 UL and CSA/CUL listed or recognized equipment To maintain UL and CSA/CUL Listing/Recognized status for North America the equipment should be installed using UL and/or CSA Listed or Recognized parts for the following items: connection cables, protective fuses/fuseholders or circuit breakers, insulation crimp terminals, and replacement internal battery, as specified in the equipment documentation.
  • Page 13: De-Commissioning And Disposal

    Safety Section P44x/EN SS/H11 (SS) - 7 External test blocks and test plugs Great care should be taken when using external test blocks and test plugs such as the MMLG, MMLB and MiCOM P990 types, hazardous voltages may be accessible when using these. *CT shorting links must be in place before the insertion or removal of MMLB test plugs, to avoid potentially lethal voltages.
