Schedule of Limitations
The component must be mounted within apparatus which provides ingress protection of at least IP20,
protection against impact, and protection against possible electrostatic charging of the plastic enclosure.
Warning:
The MiniPID sensor is an Intrinsically Safe device that contains limited energy storing components. An
appropriate Intrinsically Safe interface must be employed for use in hazardous locations noting power
limitations and temperature ranges, and must be installed in strict accordance with applicable safety codes
and guidance given in the Manual. Failure to observe this warning can result in serious injury and/or
property damage.
