120 Technical data
UL marking
The drive module is C-UL US Listed. The approval is valid with rated voltages.
UL checklist
• The drive module (IP00, UL Open Type) is to be used in a heated, indoor controlled environment. The drive
must be installed in clean air according to enclosure classification. Cooling air must be clean, free from
corrosive materials and electrically conductive dust. See page 116.
• The maximum ambient air temperature is 40 °C (104 °F) at rated current. The current is derated for 40 to
50 °C (104 to 122 °F).
• The drive is suitable for use in a circuit capable of delivering not more than 100,000 rms symmetrical
amperes, 500 V maximum. The ampere rating is based on tests done according to UL 508C.
• The cables located within the motor circuit must be rated for at least 75 °C (167 °F) in UL-compliant
installations.
• The input cable must be protected with fuses. Circuit breakers must not be used without fuses in the USA.
Suitable IEC (class gG and aR) fuses are listed on page 107 and UL (class T or L) fuses on page 110. For
suitable circuit breakers, contact your local ABB representative.
• For installation in the United States, branch circuit protection must be provided in accordance with the
National Electrical Code (NEC) and any applicable local codes. To fulfill this requirement, use the UL
classified fuses.
• For installation in Canada, branch circuit protection must be provided in accordance with the Canadian
Electrical Code and any applicable provincial codes. To fulfill this requirement, use the UL classified fuses.
• The drive provides overload protection in accordance with the National Electrical Code (NEC).
CSA marking
The drive module is CSA marked. The approval is valid with rated voltages.
