Safety precautions

Installation, wiring, testing and service must be performed in accordance with all local and national electrical codes.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
  • Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E in the USA, CSA Z462 or applicable local standards.
  • 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.
  • Treat communications and I/O wiring connected to multiple devices as hazardous live until determined otherwise.
  • Do not exceed the device’s ratings for maximum limits.
  • Do not use this device for critical control or protection applications where human or equipment safety relies on the operation of the control circuit.
  • 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.
  • Do not use the data from the meter to confirm power is off.
  • Do not perform Dielectric (Hi-Pot) or Megger testing on this device.
  • 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.
NOTE: See IEC 60950-1:2005, Annex W for more information on communications and I/O wiring connected to multiple devices.
NOTE: Do not perform Dielectric (Hi-Pot) or Megger testing on the meter because its internal surge protection circuitry starts functioning at levels below typical Hi-Pot voltages. Contact your local Schneider Electric representative for more information on device specifications and factory testing.
