1.4 Configuration including peripheral equipment
• Equipment other than the converter unit, drive unit and servo motor is optional or a recommended product.
The following is an example using the MR-J5D1-100G4 and MR-CV11K4.
The actual converter unit and drive unit are mounted closely together.
*1 When sharing the power supply of an inductive load such as a cooling fan with the main circuit of the MR-CV_, do not supply the power
from between the MR-CV_ and AC reactor or from the secondary side of the magnetic contactor to the inductive load. Connect the
inductive load on the power supply side beyond the area in the dotted line.

2INSTALLATION
Precautions
• Install the converter unit on incombustible material. Installing them either directly on or near combustibles may lead to
smoke or a fire. In addition, the converter unit must be installed in a metal cabinet.
• Provide an adequate protection to prevent the following matter from entering the converter unit: conductive matter such as
screws and metal fragments, and combustible matter such as oil.
• The converter unit may become hot. Take safety measures such as providing covers.
• Do not stack in excess of the specified number of product packages.
• Do not hold the front cover, cables, or connectors when carrying the converter unit. Doing so may cause the converter unit
to drop.
• Use the eyebolts of the converter unit for transportation only. Do not use them to transport the converter unit when it is
mounted on a machine.
• Do not overtighten the eyebolts of the converter unit. Tightening too hard may damage the tap.
• To prevent a malfunction, do not drop the converter unit or subject it to impact.
• When installing the converter unit, follow the user's manual and install the unit in a place that can support its weight.
• Do not get on the equipment or put a heavy load on it.
• Do not install or operate a converter unit that is missing parts or is damaged.
• To prevent a malfunction, do not block the intake and exhaust areas of the converter unit.
• Do not subject connectors to impacts. Doing so may cause a connection failure, malfunction, or other failures.
• Use the product within the specified environment. For details on the environment, refer to the following.
Page 8 Standard specifications
• To prevent a fire or injury from occurring in the event of an earthquake or other natural disaster, securely install, mount, and
wire the servo amplifier as stated in the user's manual.
• When the product has been stored for an extended period of time, contact your local sales office.
• When handling the converter unit, be careful with the edges of the converter unit.
• Fumigants that are used to disinfect and protect wooden packaging from insects contain halogens (such as fluorine,
chlorine, bromine, and iodine) cause damage if they enter our products. Please take necessary precautions to ensure that
any residual materials from fumigants do not enter our products, or perform disinfection and pest control using a method
other than fumigation, such as heat treatment. Perform disinfection and pest control on the wooden packaging materials
before packing the products.
• Provide an external emergency stop circuit to stop the operation and shut-off the power immediately.
• For equipment in which the moving part of the machine may collide against the load side, install a limit switch or stopper to
the end of the moving part.
• Do not use the servo amplifier in environments where it is exposed to strong magnetic fields, electric fields, or radiation.
Doing so may cause operation failure or malfunction.

12 2 INSTALLATION
2.1 Mounting direction and clearances
2.1 Mounting direction and clearances
Precautions
• The converter unit must be installed in the specified direction.
• To prevent a malfunction, maintain the specified clearances between the converter unit and cabinet walls or other
equipment.
• Circulate air so that the air at the top and bottom of the converter unit does not stagnate.
• When using heat generating equipment, install it with full consideration of heat generation so that the converter unit is not
affected.
• Mount the converter unit on a perpendicular wall in the correct vertical direction.
Installation
For details on installation, refer to the drive unit/servo amplifier user's manual and instruction manual.

2.2 Keeping out foreign materials
When drilling the cabinet for assembly, prevent drill chips and wire fragments from entering the converter unit.
Prevent foreign matter such as oil, water, and metallic dust from entering the converter unit through cooling fans installed in
openings in the cabinet or on the ceiling.
When installing the cabinet in a place where toxic gas, dirt, and dust exist, conduct an air purge (force clean air into the
cabinet from outside to make the internal pressure higher than the external pressure) to prevent such materials from entering
the cabinet.
2.3 Inspection items
Precautions
• Do not disassemble, repair, or modify the product.
• For repair and parts replacement, contact your local sales office.
• To prevent a malfunction, do not perform an insulation resistance test (megger test) on the converter unit.
Periodic inspection
Perform the following inspections.
• Check for loose terminal block screws. Retighten any loose screws.
• Check the cables and the like for scratches or cracks. Inspect them periodically according to operating conditions
especially when the servo motor is movable.
• Check that the connector is securely connected to the converter unit.
• Check that the wires are not coming out from the connector.
• Check for dust accumulation on the converter unit.
• Check for unusual noise generated from the converter unit.
• Make sure that the emergency stop circuit operates properly such that an operation can be stopped immediately and a
power is shut off by the emergency stop switch.

2.4 Parts with a service life
2.4 Parts with a service life
The service life of the following parts is listed below. In addition, the service life varies depending on the operating methods
and environment. If any fault is found in a part, it is necessary to replace it immediately regardless of its service life. For parts
replacement, please contact your local sales office.
Smoothing capacitor
The service life of the capacitor is 10 years (with a three-phase power supply input) under continuous operation in air-
conditioned environments (ambient temperatures of 40 °C or less at altitudes of up to 1000 m and 30 °C or less at altitudes of
over 1000 m and up to 2000 m). Ripple currents or other factors will deteriorate the characteristic of the smoothing capacitor.
The service life of the capacitor greatly varies depending on ambient temperature and operating conditions.
Converter unit cooling fan
The cooling fan bearings will reach the end of their service life in 10000 hours to 30000 hours. Therefore, the cooling fan must
be replaced after two to three years of continuous operation as a guideline. If unusual noise or vibration is found during
inspection, the cooling fan must also be replaced.
The service life has been calculated in an environment which contains no corrosive gas, flammable gas, oil mist, or dust. The
average annual ambient temperature was 40 °C.
Part name Recommended service life
Smoothing capacitor 10 years
Cooling fan 10000 hours to 30000 hours (2 to 3 years)

For restrictions on the drive unit/servo amplifier, refer to the drive unit/servo amplifier user's manual and instruction manual.
Effective load ratio and regenerative load ratio
As heat dissipation effects decrease in proportion to decreasing air density, use the product within the effective load ratio and
regenerative load ratio shown in the following figure.
Input voltage
Generally, withstand voltage decreases as altitude increases; however, there is no restriction on the withstand voltage.
