2. Grounding capacitor switch / screw

Prohibition	When using this 400V class inverter with a power supply system that is grounded in other than the neutral point (e.g. when the power supply has delta connection with single phase grounding), the grounding capacitor should not be grounded (or the capacity of the grounding capacitor should not be increased). Otherwise, it will result in failure or fire. Do not switch the grounding capacitor to small, if you set aul (overload characteristic selection) to 2. Otherwise, it will result in failure or fire.
Mandatory action	When using this inverter with a power supply of IT system (power supply isolated from ground or grounded through high impedance), disconnect the grounding capacitor. If a grounding capacitor with power supply of IT system is connected, it will result in failure or fire. Be sure to switch grounding capacitors with the power off. If you switch with the power on, it can result in electric shock or injury.

These inverters have a built-in EMC noise filter and the inverter input power supply is grounded via the capacitor. By switching this grounding capacitor, the leakage current from the inverter can be reduced. It is switched by changing the position of the exclusive switching screw that the grounding capacitor is completely disconnected. For the details of the influence of the leakage current and measures.
Switch the grounding capacitor in the following procedure given. Be sure to switch with the power off. At the time of shipping, the grounding capacitor is grounded.
Install the screw at grounding capacitor switch position A (), the grounding capacitor's capacity is switched from small to large.
(Default setting)
Tightening torque: 0.5 Nžm (4.4 lbžin)

Move the screw from the grounding capacitor switch position A (), the grounding capacitor's capacity is switched from large to small. This reduces the leakage current. Insert the screw into the grounding capacitor switching position B () without turning it, then, hold and store it.
When this inverter is connected to the IT system (system that power supply grounding is insulated or has impedance from the ground), the screw has to be moved as the figure shows.

Note 1) Don't switch the grounding capacitor to small, if you set aul (overload characteristic selection) to 2.

What to do about the leakage current
These inverters have a built-in EMC noise filter, so the leakage current value in the delta connection (single-phase grounding) power supply may become greater. For detail of the moving the grounding capacitor screw.

Installation
Calorific values of the inverter and the required ventilation

About 5% of the rated power of the inverter will be lost as a result of conversion from AC to DC or from DC to AC. In order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the interior of 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.

Note 1) Case of 100% Load Continuation operation. The heat loss for the optional external devices
(input AC reactor, radio noise reduction filters, etc.) is not included in the calorific values in the table
Note 2) It is power consumption when power is on but is not output (0Hz), and cooling fan is activated (model with cooling fan).

[Example of wiring]

Measures to satisfy the Low Voltage Directive

Mandatory action

Install proper short-circuit protective device between the power supply and the inverter (primary side). If proper short-circuit protective device is not installed, short circuit current cannot be shut down by inverter alone and it will result in fire. Integral solid state short circuit protection in the inverter does not provide branch circuit protection. Branch circuit protection must be provided in accordance with any local codes Take into account the minimum required prospective short-circuit current of short-circuit protective device. If short circuit protective device does not work properly due to lower level short-circuit current, it will result in electric shock or fire. Install the inverter into enclosure based on this manual, and install short-circuit protective device or power distribution devices based on the manufacturer manual. When they are installed with improper coordination, this will result in electric shock or fire. The grounding wire must be connected securely. If the grounding wire is not securely connected, when the inverter has failure or earth leakage, this will result in electric shock or fire.

Mandatory action	This product can cause a DC current in the PE conductor. Where a residual current operated protective device (RCD) is used for protection against electric shock, only an RCD of Type B is allowed on the supply side of this product. All upstream RCD, up to the supply transformer, shall be of Type B. If proper device above is not used, it can result in electric shock.
