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. Disconnect all the device’s input and output wires before performing dielectric (hi-pot) or Megger testing. Never shunt an external fuse or circuit breaker. Failure to follow these instructions will result in death or serious injury.
