Yaskawa R1000 Series Power Regenerative Unit - Manual (Page 15)

i.2 General Safety
YASKAWA ELECTRIC TOEP C710656 08B YASKAWA Power Regenerative Unit - R1000 Instruction Manual 15
■ 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.
