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, NOM-029-STPS, or local equivalent.
  • This equipment must only be installed and serviced by qualified electrical personnel.
  • Turn off all power supplying this equipment before working on or inside equipment.
  • Turn off all power supplying the downstream equipment by manually opening the circuit breaker.
  • Before working on or inside equipment, always use a properly rated voltage sensing device to confirm that power is off.
  • Replace all devices, doors, and covers before turning on power to this equipment.
  • Beware of potential hazards, and carefully inspect the work area for tools and objects that may have been left inside the equipment.
Failure to follow these instructions will result in death or serious injury.

Follow these guidelines when installing circuit breakers in equipment:

  • Respect minimum distances.

  • Perform dielectric strength tests, thermal calculations, and temperature rise tests as required by the configuration of the installation.

  • Respect the limits defined in the derating tables, depending on the ambient temperature (ratings are based on IEC/EN60947-2 standard).

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
