Suitable UL fuses are listed in section Fuses (UL) (page 299) and circuit breakers
in section Circuit breakers (IEC) (page 298).
WARNING!
The opening of the branch-circuit protective device may be an indication
that a fault current has been interrupted. To reduce the risk of fire or
electric shock, current-carrying parts and other components of the device
should be examined and replaced if damaged.
• The integral solid state short circuit protection of the drive does not provide
branch circuit protection. Branch circuit protection must be provided in
accordance with the National Electrical Code and any additional local codes.
(Exception: IP66 (UL Type 4X) drive with disconnect and fuse option (+F254)
incorporates suitable branch circuit fuses. UL98 disconnect is designed for
feeder or branch applications and so does not require upstream branch
protection.)
• The drive provides motor overload protection. For adjustments, see the
firmware manual.
• The drive overvoltage category according to IEC 60664-1 is III.
• To maintain the environment integrity of the enclosure, replace the cable
grommets with field-installed industrial conduit hubs or closure plates required
by the enclosure type (or better).
Design lifetime expectancy
The design lifetime expectancy of the drive and its overall components exceeds
ten (10) years in normal operating environments. In some cases, the drive can last
20 years or more. To achieve a long lifetime for the product the manufacturer’s
instructions for sizing the drive, installation, operational conditions and preventive
maintenance schedule shall be followed.
