Conformity with UL standards and CSA standards (cUL-listed for Canada)
UL/cUL-listed inverters are subject to the regulations set forth by the UL standards and CSA standards (cUL-listed for Canada) by
installation within precautions listed below.
1. Solid state motor overload protection (motor protection by electronic thermal overload relay) is provided in each model.
Use function codes F10 to F12 to set the protection level.
2. Use Cu wire only.
3. Use Class 1 wire only for control circuits.
4. Short circuit rating
"Suitable For Use On A Circuit Of Delivering Not More Than 100,000 rms Symmetrical Amperes, 240 Volts Maximum for
230 V class input 40 HP or below, 230 Volts maximum for 230 V class input 50 HP or above when protected by Class J
Fuses or a Circuit Breaker having an interrupting rating not less than 100,000 rms Symmetrical Amperes, 240 Volts
Maximum." Models FRN; rated for 230 V class input.
"Suitable For Use On A Circuit Of Delivering Not More Than 100,000 rms Symmetrical Amperes, 480 Volts Maximum
when protected by Class J Fuses or a Circuit Breaker having an interrupting rating not less than 100,000 rms Symmetrical
Amperes, 480 Volts Maximum." Models FRN; rated for 460 V class input.
"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."
5. Field wiring connections must be made by a UL Listed and CSA Certified closed-loop terminal connector sized for the wire
gauge involved. Connector must be fixed using the crimp tool specified by the connector manufacturer.
6. All circuits with terminals L1/R, L2/S, L3/T, R0, T0, R1, T1 must have a common disconnect and be connected to the same
pole of the disconnect if the terminals are connected to the power supply.
7. When using the inverter as a UL Enclosed Type (UL TYPE1), purchase Type 1 kit (option) and mount it on the inverter as
instructed.
