Compliance With Ul/Csa Standards - Toshiba TOSVERT VF-AS3 Instruction Manual

9. 2
The VF-AS3 models, that conform to the UL Standard and CSA Standard have the UL/CSA mark on the
nameplate.
9. 2. 1
The VF-AS3 inverter must be mounted on a wall, and used within the ambient temperature
specification.
For frame size A6, A7 and A8, a UL certificate was granted on the assumption that the inverter would
be installed in a cabinet. Therefore, install the inverter in a cabinet and if necessary, take measures to
maintain the ambient temperature (temperature in the cabinet) within the specified temperature range.
Maximum Surrounding Air Temperature is 50°C.
240V 0.4 - 55kW (HD), 0.75 - 75kW (ND)
480V 0.4 - 280kW (HD), 0.75 - 160kW (ND)
Maximum Surrounding Air Temperature is 45°C.
220 - 315kW (ND)
* Refer to [1. 2] for (HD) and (ND).
9. 2. 2
Use the UL conformed cables (Rating 75°C or more, Use the copper conductors only.) to the main
circuit terminals (R/L1, S/L2, T/L3, U/T1, V/T2, W/T3), 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 circuit
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 [9. 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], [2. 3. 5].
9. 2. 3
Install a UL conformed fuse on the input side of the inverter.
For this inverter, a UL test has been conducted under the interrupting current (current that runs when
interruption of power occurs) conditions in the table below. Note that the interrupting current varies
depending on the applicable motor output.
