■ UL standard and CSA standard
The VF-S15 models that conform to the UL Standard and CSA Standard have the UL/CSA mark on the
nameplate.
This additional sheet is correction and additional information of as appendix for section 9.2 in E6581611.
2. Compliance with Installation
A UL certificate was granted on the assumption that the inverter would be installed in an enclosure. Therefore,
install the inverter in an enclosure and if necessary, take measures to maintain the inverter ambient
temperature (temperature in the enclosure) within the specified temperature range.
Current reduction
According to the carrier frequency f300 setting, you may need to reduce the inverter’s continuous
output current.
Reduction rates vary depending on the capacity of the inverter.

3. Compliance with Connection
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 electrical shock, current-carrying parts and other components of the controller
should be examined and replaced if damaged.
If burnout of the current element of an overload relay occurs, the complete overload relay must be replaced.
