Ring terminals are recommended to be used for main circuit wiring. Make sure the
terminals are fastened before power is applied.
Ring Terminals
Ring terminals are not required by UL, but they can be used according to the UL conditions
of acceptability.
UL Conditions of Acceptability
For use only in Industrial Control Equipment where the acceptability is determined by
Underwriters Laboratories Inc.
This component controller has been judged on the basis of the required spacings in the
Standard for Power Conversion Equipment, UL 508C, Pollution Degree 2.
The following shall be considered in the final application:
1) Terminals are acceptable for factory or field wiring.
2) Device shall be installed in a suitable enclosure.
3) Failure mode testing of the voltage sensing circuit, which could result in operation of the
DC bus input at transient voltages higher than 800VDC during motor regeneration, was not
performed.
4) These devices should be mounted and used according to the manufacturer’s directions and
specifications with regard to compatibility with drive type (see Ratings Section) and braking
resistor specification.
5) The manufacturer should provide in the end product all literature designating use of the
devices as described in Condition of Acceptability 4) above.
6) Temperature testing was performed in a 150% outer enclosure and results found acceptable
for use in 25°C ambient outside of the 150% outer enclosure. Use at elevated ambients with
other enclosure configurations will require heat testing with the actual intended enclosure
and the elevated ambient.
