• The cFP-RLY-425 is a UL Recognized component. The entire
Compact FieldPoint system must be installed in a UL Listed,
suitably rated NEMA or IP enclosure for safe use.

• As with any hazardous voltage wiring, make sure that all
wiring and connections meet applicable electrical codes and
commonsense practices. Mount terminal bases and backplanes
in an area, position, or cabinet that prevents accidental or
unauthorized access to wiring that carries hazardous voltages.
• Do not use the cFP-RLY-425 as the only isolating barrier
between human contact and working voltages higher than
250 V .
rms
• Operate the cFP-RLY-425 only at or below Pollution Degree 2.
Pollution Degree 2 means that only nonconductive pollution
occurs in most cases. Occasionally, however, condensation can
cause temporary conductivity.
• Do not operate FieldPoint products in an explosive atmosphere
or where there may be flammable gases or fumes. If you need
to operate FieldPoint products in such an environment, the
FieldPoint products must be in a suitably rated enclosure.
• Operate the cFP-RLY-425 at or below Measurement
Category II. Measurement Category II is for measurements
performed on circuits directly connected to the low-voltage
installation. This category refers to local-level distribution,
such as that provided by a standard wall outlet. Do not use this
module with voltages in Measurement Categories III or IV.
