Connecting the Power Supply
This product operates on a 342V to 440V and 45Hz to 65Hz three-phase AC power supply.
To ensure proper and safe use of this product, please observe the following.
！
Mandatory
Verify that the input power supply (power supply AC 342V to 440V) is turned off when wiring input
terminals.
！
Mandatory
A noise filter is built into the device to prevent EMI (Electromagnetic Interference).
Due to this, even the slightest amount of leaked current may result in electric shock if not properly
grounded.
For safety reasons, please ground the device.
！
Mandatory
Please use input power within ranges of 342V to 440V and 45Hz to 65Hz (three-phase).
The nominal power supply voltage is displayed near the rear input connector platform.
！
Mandatory
Since it becomes a cause of failure, please do not use it with the electric supply source line in which
each voltage between phase groundings (Between L1-G, Between L2-G, and Between L3-G) is
higher than AC254V.
Three-phase three-wire system is not available. Please use three-phase four-wire system.
Set circuit breaker between feeding device and this equipment.
Connect the circuit breaker to the feeding device and the equipment.
The input power switch of the equipment is not used for cutting power from AC line completely.
The breaker should be compliant with IEC60947-1 and IEC60947-3.
The breaker should be installed the position where the equipment can reach easily.
The breaker should be exclusive use of this equipment.
Indicate that the device is used for cutting power from AC line
and Function (ON [|], OFF[○].

Mandatory
Please connect maximum power consumption to a possible power supply.
！
Mandatory
For wiring to the connector platform, be sure to connect it tightly.
Fastening loosely may cause heating and burnout of the connector platform.
！
Mandatory
The cross-section area of the wiring material should be sufficient against load current.
Please refer to the Appendix 4 "Loaded Current vs Recommended Conductor Area" (page214)
when you select the wiring material.
Maximum Input Current is displayed near the input terminals at rear side.
