Safety precautions

Installation, wiring, testing and service must be performed in accordance with all local and national electrical codes.
  • Apply appropriate Personal Protective Equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462 or other local standards.
  • Turn off all power supplying this device and the equipment in which it is installed before working on or in the equipment.
  • Always use a properly rated voltage sensing device to confirm that all power is off.
  • Follow guidelines in the Wiring section of the related Installation Sheet.
  • Assume communications and I/O wiring are hazardous live until determined otherwise.
  • Do not exceed the maximum ratings of this device.
  • Do not short secondary terminals of Voltage Transformer (VT).
  • Do not open secondary terminals of Current Transformer (CT).
  • Ground secondary circuit of CTs.
  • Do not use the data from the meter to confirm power is off.
  • Replace all devices, doors and covers before turning on power to this equipment.
  • Do not install CTs or LPCTs in equipment where they exceed 75% of the wiring space of any cross-sectional area in the equipment.
  • Do not install CTs or LPCTs in areas where ventilation openings may be blocked or in areas of breaker arc venting.
  • Secure CT or LPCT secondary conductors to ensure they do not contact live circuits.
  • Do not use water or any liquid material to clean the product. Use a cleaning cloth to remove dirt. If dirt cannot be removed, contact local Technical Support representative.
  • The installer is responsible for coordinating the rating and the characteristics of the supply side over current protection devices with the maximum current rating.
Failure to follow these instructions will result in death or serious injury.

NOTE: See IEC 60950-1 for more information on communications and I/O wiring connected to multiple devices.

Unintended Operation
  • Do not use this device for critical control or protection of persons, animals, property or equipment.
  • Do not use this device if a wrench icon appears on the top left corner of the display screen or if the value under Meter Status is not “OK”.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Potential compromise of system availability, integrity, and confidentiality
  • Change default passwords/passcodes to help prevent unauthorized access to device settings and information.
  • Disable unused ports/services and default accounts, where possible, to minimize pathways for malicious attacks.
  • Place networked devices behind multiple layers of cyber defenses (such as firewalls, network segmentation, and network intrusion detection and protection).
  • Use cybersecurity best practices (for example: least privilege, separation of duties) to help prevent unauthorized exposure, loss, modification of data and logs, interruption of services, or unintended operation.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
