The VF-AS3 models, that conform to the UL Standard and CSA Standard have the UL/CSA mark on the
nameplate.
3. 2. 1 Compliance with Installation
The totally enclosed box type of VF-AS3 series are provided in a Type 12 enclosure with installation of
the top cover included in the package. They are provided in a Type 1 enclosure without the top cover.
These inverters must be mounted on a wall, and used within the ambient temperature specification.
Maximum Surrounding Air Temperature is 40°C.
480V 0.4 - 75kW (HD), 0.75 - 90kW (ND)
3. 2. 2 Compliance with Connection
• Use the UL conformed cables (Rating 75°C or more for 45kW/VFAS3-4370PCE or smaller, Rating
90°C or more for 55kW/VFAS3-4450PCE or larger, Use the copper conductors only.) to the main cir-
cuit terminals (R/L1, S/L2, T/L3, U/T1, V/T2, W/T3).
• Use the UL-certified electric wire for FLA, FLB, FLC, R1A, R1C, R2A and R2C terminals.
• For instruction in the United States, 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.
• For instruction in the Canada, Integral solid state short circuit protection does not provide branch cir-
cuit protection. Branch circuit protection must be provided in accordance with the Canadian Electrical
Code and any additional local codes.
• For recommended tightening torque, see [2. 3. 3]
• For recommended electric wire sizes, see [3. 2. 3]
• Use the electric wire of Class1 for the control circuits.
For details of wiring, terminals and the functions, refer to [2. 3. 2], [2. 3. 3], [2. 3. 4] and for control
terminal refer to [2. 3. 5] of E6582062.
