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 or applicable local standards.
• Turn off all power supplying this device before working on it.
• Always use a properly rated voltage sensing device to confirm that all power is off.
• 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 voltage transformer (VT).
• Never open circuit a current transformer (CT).
• Always use grounded external CTs for current inputs.
Failure to follow these instructions will result in death or serious injury.
