Appendix D—Safety instructions for UL and cUL
CAUTION
The UL and cUL compliance can be maintained only if
this drive is installed according to the requirements of
AppendixD —Safety Instructions for UL and cUL. Failure
to follow these instructions may result in UL and cUL
non-compliance.
UL Standards compliance
This drive is tested in accordance with UL508C and
CSAC22.2 No. 274-13 and CSA C22.2 No. 274-17 and
is found to comply with these requirements. To ensure
continued compliance when usingthis drive or when
usingitin combination with otherequipment, meet the
following conditions.
General
This drive shall be applied in accordance with the
specifications detailed in Table 20.
Overvoltage category
To comply with standard CSA C22.2 No. 274-13 and
CSAC22.2 No. 274-17 requirement, the following applies
tocUL applications:
•
This drive should be installed in environment of
Overvoltage Category III
•
For 480 V Series: It is recommended that transient
surge suppression be installed on the line side of this
equipment and be rated 500 V (phase to ground), suitable
for Overvoltage Category III, and shall provide protection
forarated impulse withstand voltage peak of6kV
•
For 230 V Series: It is recommended that transient
surge suppression be installed on the line side of this
equipment and be rated 240 V (phase to ground), suitable
for Overvoltage Category III, and provide protection for a
ratedimpulse withstand voltage peak of 4 kV
•
For 575 V Series: It is recommended that transient surge
suppression be installed on the line side of this equipment
and be rated 600 V (phase to ground), suitable for
Overvoltage Category III, and shall provide protection for a
rated impulse withstand voltage peak of 6 kV
Motor overload and over-temperature protection
This drive provides solid-state motor overload protection. The
solid-state motor overload protection limit is adjustable, see
the drives application manual for more details.
This drive can accept and act upon a signal from a thermal
sensor or switch embedded in the motor or from an external
protective relay to achieve the motor over temperature
protection. Therefore, in order to achieve the motor over
temperature protection, a sensor from the motor will be
needed.
