    2. PRODUCT SPECIFIC SAFETY INFORMATION Measurement Category IV (CAT IV) is applicable to test and measuring equipment connected at the source of the building’s low- voltage MAINS installation. The specified measurement category means the phase sequence indicator will be safe to the user if inadvertently connected to a voltage up to 600V AC/DC to earth within a CAT IV environment.
  • Page 6 The socket tester is not intended to determine if circuits being tested are dead. The correct testing methods should be used to do this. If the LED indicators do not illuminate, this does not necessarily mean all three phases under test are dead. Two phases could be open circuit, but one phase could still be live.

Note 1: If none of the LED’s illuminate, this does not necessarily mean all three phases under test are dead. Two phases could be open circuit, but one phase could still be live. Note 2: The colours of the cables under test cannot be relied upon to conform to the expected phases.
