CAUTION
i.3 Notes for Safe Operation
◆ Receiving
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 (Refer to page 12)
◆ Installation
Lift the cabinet by the base. When moving the unit, never lift by the front cover or the front panel.
Otherwise, the main unit may be dropped causing damage to the unit. (Refer to page 16)
Mount the power regenerative unit on nonflammable material (i.e. metal).
Failure to observe this caution can result in a fire. (Refer to page 16)
When mounting units in an enclosure, install a fan or other cooling device to keep the intake air temperature below 45°C.
Overheating may cause a fire or damage to the unit. (Refer to page 16)
In order to comply to UL regulations, the MOV and current suppression reactor must be installed on the input of the R5 unit.
Refer to the installation diagram. (Refer to page 16)
◆ Wiring
Only commence wiring after verifying that the power supply is turned OFF.
Failure to observe this warning can result in an electric shock or a fire. (Refer to page 24)
Wiring should be performed only by qualified personnel.
Failure to observe this warning can result in an electric shock or a fire. (Refer to page 24)

• 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.

2.1 Section Safety
CAUTION
2.1 Section Safety
Lift the cabinet by the base. When moving the unit, never lift by the front cover or the front panel.
Otherwise, the main unit may be dropped causing damage to the unit.
Mount the power regenerative unit on nonflammable material (i.e. metal).
Failure to observe this caution can result in a fire.
When mounting units in an enclosure, install a fan or other cooling device to keep the intake air temperature below 45°C.
Overheating may cause a fire or damage to the unit.

2.2 Checking Installation Site
2.2 Checking Installation Site
◆ Installation Site
Install the power regenerative unit under the following conditions.
NOTICE: Do not install the power regenerative unit to an area greater than pollution degree 2 (UL standard).
Typ e Ambient Operating Temperature Humidity
Enclosed wall-mounted –10 to +40°C 90% RH or less (no condensation)
Open chassis –10 to +45°C 90% RH or less (no condensation)
Protection covers are attached to the top and bottom of the power regenerative unit. Be sure to remove the protection covers before installing a 200
or 400 V Class power regenerative unit with an output of 30 kW or less in a panel.
To ensure proper performance and long operating life, follow the recommendations below when choosing a location for installing the RC5. Make
sure the power regenerative unit is protected from the following conditions:
• Extreme cold and heat.
Use only within ambient temperature range: -10°C to +40°C
• Rain, moisture. (For enclosed wall-mounted type)
• Oil sprays, splashes
• Salt spray.
• Direct sunlight. (Avoid using outdoors.)
• Corrosive gases or liquids.
• Dust or metallic particles in the air. (For enclosed wall-mounted type)
• Physical shock, vibration.
• Magnetic noise. (Example: welding machines, power devices, etc.)
• High humidity.
• Radioactive materials.
• Combustibles: thinners, solvents, etc.
◆ Controlling the Ambient Temperature
To enhance the reliability of operation, the power regenerative unit should be installed in an environment free from extreme temperature increases. If
the power regenerative unit is installed in an enclosed environment, such as a box, use a cooling fan or air conditioner to maintain the internal air
temperature below 45°C.
◆ Protecting the Power Regenerative Unit from Foreign Matter
Place a cover over the power regenerative unit during installation to shield it from metal power produced by drilling.
Always remove the cover from the power regenerative unit after completing installation. Otherwise, ventilation will be reduced, causing the power
regenerative unit to overheat.

2.3 Clearances
Install the RC5 vertically and allow sufficient clearances for effective cooling as shown in Figure 2.1.
Figure 2.1
Note: 1. The clearances required at top/bottom and both sides are common in open chassis type (IP00) and enclosed wall–mounted type (NEMA 1).
Figure 2.1 Clearances
2. Remove the top and bottom covers to use the open chassis type of 200 V/400 V 30 kW or less.
3. When installing the models of 200 V/400 V 37 kW or more equipped with eyebolts, extra spacing will be required on either side. For detailed dimensions, contact your
YASKAWA representative.
4. Ensure sufficient space for the sections at the upper and lower parts marked with * in order to permit the flow of intake/exhaust air to / from the unit.
