Note: Do not install in any location where there is high humidity or high temperatures and where there are large amounts of dust, metallic fragments and oil mist. If you are going to install the equipment in any area that presents a potential problem, please consult with Toshiba before doing so.
■ Calorific values of the inverter and the required ventilation
The energy loss when the inverter converts power from AC to DC and then back to AC is about 5 percent. In |
| |
order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the interior of |
| |
1 | ||
the cabinet must be ventilated and cooled. | ||
| ||
|
|
The amount of forcible air cooling ventilation required and the necessary heat discharge surface quantity when operating in a sealed cabinet according to motor capacity are as follows.

Notes
1)The heat loss for the optional external devices (input reactor, DC reactor, radio noise reduction filters, etc.) is not included in the calorific values in the table.
2)Case of 100% Load Continuation operation.
■Panel designing taking into consideration the effects of noise.
The inverter generates high frequency noise. When designing the control panel setup, consideration must be given to that noise. Examples of measures are given below.
•Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the same conduit, do not run them parallel, and do not bundle them.
•Provide shielding and twisted wire for control circuit wiring.
•Separate the input (power) and output (motor) wires of the main circuit. Do not place them in the same conduit, do not run them parallel, and do not bundle them.
•Ground the inverter ground terminals (
).
