  • Turn off all power supplying this device and the equipment in which it is installed before working on the device or equipment.
  • Always use a properly rated voltage sensing device to confirm that all power is off.
  • Never bypass external fusing. Install properly rated fuses in voltage measurement circuits and in auxiliary (control) power circuit.
  • Do not exceed the device’s ratings for maximum limits.
  • Never short the secondary of a potential/voltage transformer (PT/VT).
  • Never open circuit a current transformer (CT).
  • Always use grounded external CTs for current inputs.
  • Connect protective ground (earth) before turning on any power supplying this device.
  • Replace all devices, doors and covers before turning on power to this equipment.
  • All electrical connections to the meter terminals must not be user-accessible after installation.
Failure to follow these instructions will result in death or serious injury.

For existing installations, verify that the wiring and all required elements (fuses, etc.) are properly installed and working. For new installations, follow local and national electrical standards and refer to the documentation provided by the socket base manufacturer.
