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, 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. Assume communications and I/O wiring are hazardous live until determined otherwise. Do not exceed the maximum ratings of this device. 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.
