Canada
11.2.1

General

Originally, the UL standards were established by Underwriters Laboratories, Inc. as private criteria for
inspections/investigations pertaining to fire/accident insurance in the USA. The UL marking on Fuji
products is related to the UL Standard UL508C.
cUL certification means that UL has given certification for products to clear CSA Standards. cUL
certified products are equivalent to those compliant with CSA Standards. The cUL marking on Fuji
products is related to the CSA Standard C22.2 No. 14.

Conformity with UL standards and 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 75°C (167°F) 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 230V class input 25 HP or less, 230 Volts Maximum for 230V class input
30 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
230V 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 460V class input.
"Suitable For Use On A Circuit Of Delivering Not More Than 100,000 rms Symmetrical Amperes,
600 Volts Maximum when protected by Class J Fuses or a Circuit Breaker having an interrupting
rating not less than 100,000 rms Symmetrical Amperes, 600 Volts Maximum. Models FRN; rated
for 575V 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.
