•
Operate the cFP-RLY-423 only at or below Pollution Degree 2.
Pollution Degree 2 means that only nonconductive pollution
occurs in most cases. Occasionally, however, a temporary
conductivity caused by condensation must be expected.
•
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-423 at or below Installation Category II.
Installation Category II is for measurements performed on
circuits directly connected to the electrical distribution system.
This category refers to local-level distribution, such as that
provided by a standard wall outlet.
