NOTES
Applications of the VS-656RC5
Selection
■Use 1:1 with an inverter. Do not connect more than one inverter to one VS-656RC5.
■Use a VS-656RC5 whose capacity is equal to one exceeding the capacity of the inverter to be connected.
■Do not connect the VS-656RC5 in parallel with another power regenerative unit.
■When power regeneration is executed continuously using ○
＋ 3 terminal of the VS-686SS5,
set the maximum to 80%. If more regeneration is necessary, use a larger capacity VS-656RC5
sand inverter.
Installation
■Avoid oil mist or dust. Place the inverter in a clean area or house it in a totally-enclosed case so that no
contamination enters.To use the totally-enclosed case, select the cooling method and panel dimensions so the
VS-656RC5 ambient temperature will be within the allowable range.
■Do not install the VS-656RC5 on flammable material, such as wood.
■Install the VS-656RC5 on a wall with the longer side in the vertical position.
■Do not subject the inverter to halogen gases, such as fluorine, chlorine, bromine, and iodine, at any time
even during transportation or installation.
Operation
■Applying power to the VS-656RC5, DOUBLE CHECK WIRING AND SEQUENCE BEFORE TURNING THE
POWER ON.
■After turning the power of the VS-656RC5 OFF, electric charges in the internal capacitors are retained
temporarily.Wait until the change LED goes off before touching the inside of the VS-656RC5.
■Use round pressure terminal when wiring UL and c-UL listed VS-656RC5. Caulking shoud be done by the
caulking tools specified by terminal manufactures.
■The VS-656RC5 cannot be used with a single-phase power supply. Make sure to use a three-phase power
supply.
Applications of the Peripheral Devices
■Installation and selection of an AC reactor
An input three-phase reactor corresponding to each model is necessary when operating the VS-656RC5.
For selection of a reactor, see p.10 and 11. This input AC reactor is effective against saturated currents
and excessive heat.
■Installation and selection of fuses
Connect a fuse on the primary side of the power suppressing reactor. For selection of a fuse, see p.12.
■Installation of a noise filter
When adding an input noise filter to the inverter, connect it to the primary side of the power coordinating
reactor.
