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 200V class input 22 kW or less, 230 Volts maximum for 200V class input 30 kW 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 200V 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 400V 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.
