E6581611B-22WarningBe Grounded Ground must be connected securely.If the ground is not securely connected, it could lead to electric shock or fire.CautionProhibited Do not attach devices with built-in capacitors (such as noise filters or surge absorber) to the output(motor side) terminal.This could cause a fire.■ Preventing radio noiseTo prevent electrical interference such as radio noise, separately bundle wires to the main circuit's powerterminals (3-phase models: R/L1, S/L2, T/L3, single-phase models: R/L1, S/L2/N) and wires to the motorterminals (U/T1, V/T2, W/T3).■ Control and main power supplyThe control power supply and the main circuit power supply for this inverter are the same.If a malfunction or trip causes the main circuit to be shut off, control power will also be shut off. Whenchecking the cause of the malfunction or the trip, use the trip holding retention selection parameter.In addition, please use an optional control power supply backup unit when only control power supplyoperates, even if the main circuit is shut off due to trouble or tripping.■ Wiring Because the space between the main circuit terminals is small, use sleeved crimp-style terminals for theconnections. Connect the terminals so that adjacent terminals do not touch each other. For grounding terminal use wires of the size that is equivalent to or larger than those given in table10.1 and always ground the inverter (240V voltage class: D type ground, 500V voltage class: C typeground).Use as large and short a grounding wire as possible and wire it as close as possible to the inverter. For the sizes of electric wires used in the main circuit, refer to the table in section 10.1. The length of each wire does not exceed 30 meters. If the wire is longer than 30 meters, the wire size(diameter) must be increased.
