1.1 MELSERVO MR-J4 relevant manuals
This installation guide explains how to mount MR-J4-T20.
If you have any questions about the operation of the equipment described in this guide, contact your local sales office.
In addition, when you mount a protective device, specific technical skills which are not detailed in the guide will be
required.
1.2 Purpose of this guide
This installation guide explains for engineers of machinery manufacturers and machine operators. For detailed
information of the products, refer to "MR-J4-_B_-RJ020 MR-J4-T20 Servo Amplifier Instruction Manual".
2. About safety
This chapter explains safety of users and machine operators. Please read the chapter carefully before mounting the
equipment. In this installation guide, the specific warnings and cautions levels are classified as follows.
WARNING
Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight injury to
personnel or may cause physical damage.
2.1 Professional engineer
Only professional engineers should mount MR-J4-T20.
Here, professional engineers are persons who have taken proper engineering training.
Please note if you can take proper engineering training at your local Mitsubishi Electric office. Contact your local sales
office for schedules and locations.
2.2 Correct use
Use MR-J4-T20 within specifications. Refer to chapter 7 of this installation guide for specifications such as voltage,
temperature, etc.
Mitsubishi Electric Co. accepts no claims for liability if the equipment is used in any other way or if modifications are
made to the device, even in the context of mounting and installation.
2.2.1 Selection of peripheral equipment and wire
For selection example of MCCB, fuse, and wires for servo amplifiers on which MR-J4-T20 is mounted, refer to "MR-J4-
_B_-RJ020 MR-J4-T20 Servo Amplifier Instruction Manual".
MR-J4-T20 has a part for grounding on the frame (FG). Fix the metal part FG of MR-J4-T20 with a screw to ground.
2.2.2 EU compliance
The EC directives were issued to standardize the regulations of the EU countries and ensure smooth distribution of
safety-guaranteed products. The CE marking proves the compliance of the manufacturer with the EC directives, and this
marking also applies to machines and equipment incorporating servos.
(1) EMC requirement
Servo amplifiers on which MR-J4-T20 is mounted comply with category C3 in accordance with IEC/EN 61800-3. As
for I/O wires (max. length 10 m) and encoder cables (max. length 50 m), use shielded wires and ground the
shields. Use an EMC filter and surge protector on the primary side. The following shows recommended products.
EMC filter: Soshin Electric HF3000A-UN series
Surge protector: Okaya Electric Industries RSPD series Line noise filter: Mitsubishi Electric FR-BIF
MR-J4 Series are not intended to be used on a low-voltage public network which supplies domestic premises;
radio frequency interference is expected if used on such a network.
The installer shall provide a guide for Installation and use, including recommended mitigation devices. To avoid the
risk of crosstalk to signal cables, the installation instructions shall either recommend that the power interface cable
be segregated from signal cables.
(2) For Declaration of Conformity (DoC)
Hereby, MITSUBISHI ELECTRIC EUROPE B.V. declares that the servo amplifiers with J4-T20 are in compliance
with EC directives (Machinery directive (2006/42/EC), EMC directive (2014/30/EU), Low voltage directive
(2014/35/EU), and RoHS directive (2011/65/EU)). For the copy of Declaration of Conformity, contact your local
sales office.
2.2.3 South Korea compliance
This product complies with the Radio Wave Law (KC mark). However, some applications are being processed. For the
situation of compliance, contact your local sales office. Please note the following to use the product.

(The product is for business use (Class A) and meets the electromagnetic compatibility requirements. The seller and the
user must note the above point, and use the product in a place except for home. In addition, use an EMC filter, surge
protector, ferrite core and line noise filter on the primary side for inputs. Use a line noise filter for outputs of 200 V class
and 100 V class servo amplifiers. Use a ferrite core and line noise filter for outputs of 400 V class servo amplifiers. Use a
distance greater than 30 m between the product and third party sensitive radio communications for an MR-J4-22KB_.)
2.2.4 Compliance with global standards
MR-J4-T20 complies with the following global standards.
Unit CE KC
MR-J4-T20
2.2.5 Compliance with standards
MR-J4-T20 complies with the following standard.
IEC/EN/KN 61800-3/GB 12668.3
2.3 General cautions for safety protection and protective measures
Observe the following items to ensure proper use of the servo amplifiers on which MR-J4-T20 is mounted.
(1) Only qualified personnel and professional engineers should perform system installation.
(2) When mounting, installing, and using the servo amplifiers, always observe standards and directives applicable in
the country.
(3) The servo amplifiers fulfill the requirements to conducted emissions at the main connections in the frequency range
from 150 kHz to 30 MHz. (Bases for the evaluation: Product standard IEC/EN 61800, adjustable speed electrical
power drive systems, Part 3: EMC)
2.4 Disposal
Disposal of unusable or irreparable devices should always occur in accordance with the applicable country-specific waste
disposal regulations. (Example: European Waste 16 02 14)
3. Mounting/dismounting
CAUTION
The devices must be installed in the specified direction. Not doing so may cause a malfunction.
Mount the servo amplifier on a cabinet which meets IP54 in the correct vertical direction to
maintain pollution degree 2.
The regenerative resistor supplied with 11 kW to 22 kW servo amplifiers does not have a
protective cover. Touching the resistor (including wiring/screw hole area) may cause a burn injury
and electric shock. Even if the power was shut-off, be careful until the bus voltage discharged
and the temperature decreased because of the following reasons.
It may cause a burn injury due to very high temperature without cooling.
It may cause an electric shock due to charged capacitor of the servo amplifier.
The following shows an example of MR-J4-350B-RJ020 or less, MR-J4-200B4-RJ020 or less, and MR-J4-40B1-RJ020.
For others, refer to "MR-J4-_B_-RJ020 MR-J4-T20 Servo Amplifier Instruction Manual".
