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.
• 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.
• Replace all devices, doors and covers before turning on power to this
equipment.

WARNING
UNINTENDED OPERATION
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Do not use this device for critical control or protection applications where human
or equipment safety relies on the operation of the control circuit.
WARNING
POTENTIAL COMPROMISE OF SYSTEM AVAILABILITY, INTEGRITY, AND
CONFIDENTIALITY
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
• Change default passwords 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.
