inspection of the RC5. In this manual, NOTES FOR SAFE OPERA TION are classified
as “WARNING” or “CAUTION”.
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death
or serious injury to personnel.
CAUTION
Indicates a potentially hazardous situation which, may result in minor or moderate
injury to personnel, and possible damage to equipment if not avoided. It may also be
used to alert against unsafe practices.
Items described in may also result in a vital accident in some situations. In
CAUTION
either case, follow these important notes.
The warning symbols for ISO and JIS standards are different, as shown below.
ISO JIS
The ISO symbol is used in this manual. Both of these symbols appear on the warning
labels on Yaskawa products. Please abide by these warning labels regardless of which

1. RECEIVING
CAUTION
• Do not install or operate any power regenerative unit which is
damaged or has missing parts.
Failure to observe this caution may result in personal injury or
equipment damage.
1.1 Inspection Checkpoints
After unpacking the RC5, check the following:
• Verify that the part numbers match your purchase order or packing slip.
• Check the unit for physical damage that may have occurred during shipping.
If any part of RC5 is missing or damaged, call for service immediately.
• Checking the Nameplate

Protective Structure
• Open Chassis Type (IEC IP00)
Protected so that parts of the human body cannot reach electrically charged parts
from the front when the Power regenerative unit is mounted in a control panel.
• Enclosed Wall-mounted Type (IEC IP20, NEMA 1)
The power regenerative unit is structured so that the power regenerative unit is
shielded from the exterior, and can thus be mounted to the interior wall of a standard
building (not necessarily enclosed in a control panel). The protective structure
conforms to the standards of NEMA 1 in the USA.

power regenerative unit.
2. Use the power regenerative unit whose capacity is equal to or exceeding
the inverter capacity to be combined.
3. Do not use this unit with single-phase power. Use three-phase power.
