Do not use this device for personnel protection
Using this device for personnel protection could result in serious injury or death.
This device does not include the self-checking redundant circuitry necessary to allow its use in
personnel safety applications. A device failure or malfunction can cause either an energized (on) or de-
energized (off) output condition.
