Caution Do not disconnect I/O-side wires or connectors
unless power has been switched off or the area is known
to be nonhazardous.
Caution Do not remove modules unless power has been
switched off or the area is known to be nonhazardous.
Caution Substitution of components may impair
suitability for Class I, Division 2.
Caution For Zone 2 applications, install the Compact
FieldPoint system in an enclosure rated to at least IP 54
as defined by IEC 60529 and EN 60529.
Caution For Zone 2 applications, install a protection
device across the external power supply and the COM
terminal. The device must prevent the external power
supply voltage from exceeding 42 V if there is a transient
overvoltage condition.
