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, 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.
"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 must have a common disconnect and be connected to
the same pole of the disconnect if the terminals are connected to the power supply.
