Enclosure Considerations
Consider the following when choosing your DG safety relay and tap enclosure.
DG Safety Relay
The DG safety relay is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in
IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This
equipment is considered Group 1, Class A industrial equipment according to
IEC/CISPR 11. Without appropriate precautions, there can be difficulties
with electromagnetic compatibility in residential and other environments due
to conducted and radiated disturbances.
The DG safety relay is supplied as open-type equipment. It must be mounted
within an enclosure that is suitably designed for those specific environmental
conditions that are present and appropriately designed to help prevent personal
injury that results from accessibility to live parts. The enclosure must have
suitable flame-retardant properties to help prevent or minimize the spread of
flame that complies with a flame spread rating of 5VA, V2, V1, V0 (or
equivalent) if non-metallic. The interior of the enclosure must be accessible
only by the use of a tool. Subsequent sections of this publication may contain
additional information regarding specific enclosure type ratings that are
required to comply with certain product safety certifications.
