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 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 should be operated at a maximum ambient
temperature of 40°C in low overload (VT) rating and 50°C
in high overload (CT) rating
●
This drive should be installed in environment of
Pollution Degree 2 or better
Overvoltage Category
To comply with standard CSA C22.2 No. 274-13 requirement,
the following applies to cUL applications:
●
This drive should be installed in environment of
Overvoltage Category III
●
For 400V Series
: Transient surge suppression shall be
installed on the line side of this equipment and shall be
rated 500V (phase to ground), suitable for Overvoltage
Category III, and shall provide protection for a rated
impulse withstand voltage peak of 6 kV
●
For 230V Series
: Transient surge suppression shall be
installed on the line side of this equipment and shall be
rated 240V (phase to ground), suitable for Overvoltage
Category III, and shall provide protection for a rated
impulse withstand voltage peak of 4 kV
Motor Overload and Over-Temperature Protection
●
This drive provides solid-state motor overload protection
that reacts when it reaches 102.5% of FLA
●
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
Branch Circuit Short Circuit Protection
●
Integral solid-state short circuit protection does not
provide branch circuit protection. Branch circuit protection
must be provided in accordance with the National
Electrical Code and any additional local codes
●
400V Drive Series are suitable for use on a circuit capable
of delivering not more than 100,000 rms symmetrical
amperes, 500 volts maximum, when protected by UL and
cUL/CSA Recognized Class T fuse with an A.I.C. rating of
100 kA minimum. Refer to the following information for
recommended fuse ratings. See
