■

Installing Standard Configuration Devices

Each regenerative unit requires a corresponding set of input fuses, power coordinating reactor, and current suppression
reactor. Always install the specified devices.

■

Installation

Enclosure Panels

Keep the regenerative unit in a clean environment by installing the regenerative unit in an enclosure panel or selecting an
installation area free of airborne dust, lint, and oil mist. Be sure to leave the required space between regenerative units to
provide for cooling, and take proper measures so the ambient temperature remains within allowable limits and keep
flammable materials away from the regenerative unit. Yaskawa offers protective designs for regenerative units that must
be used in areas subjected to oil mist and excessive vibration. Contact Yaskawa or your Yaskawa agent for details.

Installation Direction

NOTICE: Install the regenerative unit upright as specified in the manual. Refer to

Mechanical Installation on page 23

for more

information on installation. Failure to comply may damage the regenerative unit due to improper cooling

■

General Handling

Wiring Check

NOTICE: Do not connect power supply lines to output terminals. Failure to comply will destroy the regenerative unit. Be sure to perform

a final check of all sequence wiring and other connections before turning on the power and also check for short circuits on the control

terminals, which may damage the regenerative unit.

Inspection and Maintenance

WARNING! Electrical Shock Hazard. Capacitors in the regenerative unit do not immediately discharge after shutting off the power. Wait

for at least the amount of time specified on the regenerative unit before touching any components after shutting off the power. Failure to

comply may cause injury to personnel from electrical shock.
WARNING! Burn Hazard. Because the heatsink can get very hot during operation, take proper precautions to prevent burns. When

replacing the cooling fan, shut off the power and wait at least 15 minutes to be sure that the heatsink has cooled down. Failure to

comply may cause burn injury to personnel.

To connect or perform maintenance for the standard configuration devices, turn off the power supply to the regenerative
unit, wait for the time that is given on the regenerative unit, and then confirm that the temperature of the reactor has
sufficiently decreased before you proceed.

Wiring

Yaskawa recommends using ring terminals on all models. Regenerative units require the use of ring terminals for UL/cUL
compliance. Use only the tools recommended by the terminal manufacturer for crimping.

Transporting and Installing the Regenerative Unit

NOTICE: Never steam clean the regenerative unit. During transport, keep the regenerative unit from coming into contact with salts,

fluorine, bromine, phthalate ester, and other such harmful chemicals.
CAUTION! Crush Hazard. Carry all standard configuration and peripheral devices in a method suitable for the weight of the device.

Incorrectly handling devices could cause them to fall and result in injury or damage to the device.

Always use a three-phase power supply. The regenerative unit cannot be used with a single-phase power supply.
