caution
- Motors misapplied in hazardous environments can cause a fire or explosion, resulting in destruction of property, serious injury or death

- Service center personnel can advise what listings and approvals motors carry, but cannot evaluate nor recommend what motors may be suitable for use in hazardous environments
