1. About the manual
To use the MELSERVO-JN series safely, read each instruction manual carefully.
1.1 MELSERVO-JN relevant manual
This installation guide explains how to mount MR-JN servo amplifiers.
If you have any questions about the operation or programming 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 the safe operation of MR-JN servo amplifiers for engineers of machinery manufacturers
and machine operators. For detailed information of the products, refer to "MR-JN-_A 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 physical damage.
2.1 Professional engineer
Only professional engineers should mount MR-JN servo amplifiers.
Here, professional engineers should meet all the conditions below.
(1) Persons who took a proper training of related work of electrical equipment or persons who can avoid risk based on
past experience.
(2) Persons who have read and familiarized himself/herself with this installation guide.
2.2 Applications of the device
MR-JN servo amplifiers comply with the following standards.
IEC/EN 61800-5-1/GB 12668.501, IEC/EN/KN 61800-3/GB 12668.3
2.3 Correct use
Use the MR-JN servo amplifiers within specifications. Refer to each instruction manual 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.
WARNING
If you need to get close to the moving parts of the machine for inspection or others, ensure
safety by confirming the power off, etc. Otherwise, it may cause an accident.
It takes 15 minutes maximum for capacitor discharging. Do not touch the unit and terminals
immediately after power off.
2.3.1 Selection of peripheral equipment and wire
The followings are selected based on IEC/EN 61800-5-1, UL 508C, and CSA C22.2 No. 274.
(1) Local wiring
The following table shows the stranded wires [AWG] rated at 75 °C/60 °C.

Note 1. Select wire sizes depending on the rated output of the servo motors. The values in the table are sizes based on the rated output of the
servo amplifiers.
2. The following shows the PE terminal specifications of the servo amplifier.
Screw size: M4
Tightening torque: 1.2 [N•m]
Recommended crimp terminal: R2-4 (JST)
Crimping tool: YPT-60-21 (JST)
3. To wire with the servo motor, use MR-PWS1CBL (option). To extend the wiring, use the AWG 14 wire size.
(2) Selection example of MCCB and fuse
Use a fuse (T class) or the molded-case circuit breaker (UL 489 Listed MCCB) indicated in the table below. The T
class fuses and molded-case circuit breakers in the table are selected examples based on rated I/O of the servo
amplifiers. When you select a smaller capacity servo motor to connect it to the servo amplifier, you can also use
smaller capacity T class fuses or molded-case circuit breaker than ones in the table. For selecting ones other than
Class T fuses and molded-case circuit breakers below, refer to "MR-JN-_A Servo Amplifier Instruction Manual".

(3) Power supply
This servo amplifier can be supplied from star-connected supply with grounded neutral point of overvoltage
category set forth in IEC/EN 60664-1 and shown in the table of section 8.1. However, when you use the neutral
point for single phase supply, a reinforced insulating transformer is required in the power input section. For the
interface power supply, use an external 24 V DC power supply with reinforced insulation on I/O terminals.
(4) Grounding
To prevent an electric shock, always connect the protective earth (PE)
terminal (marked
) of the servo amplifier to the protective earth (PE) of
the cabinet. Do not connect two grounding cables to the same protective
earth (PE) terminal. Always connect cables to the terminals one-to-one.
If using an earth-leakage current breaker, always ground the protective
earth (PE) terminal of the servo amplifier to prevent an electric shock.
This product can cause a DC current in the protective earthing conductor.
To protect direct/indirect contact using an earth-leakage current breaker
(RCD), only an RCD of type B can be used for the power supply side of
the
roduct.

PE terminals
(5) Motor overload and Over temperature protection
Servo motors do not have the overheat protection function of own. The servo motors are protected by the servo
motor overheat protection function of the servo amplifiers (a protection characteristic based on 120 % of the rated
current). To provide the servo motor with overheat protection, use a magnetic contactor (electromagnetic switch)
with a thermal relay. Alternatively, install a thermal sensor or equivalent equipment near the rating plate of the
servo motor to check that the servo motor temperature is under 105 °C with sensing device. (Refer to Chapter 4)
2.3.2 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
MR-JN servo amplifiers comply with IEC/EN 61800-3. Install an EMC filter and surge protector on the primary side
of the servo amplifier. As for I/O signal wires (max. length 10 m) and encoder cables (max. length 50 m), use
shielded wires and ground the shields. The following shows recommended products.
EMC filter: Soshin Electric HF3000A-UN series
Surge protector: Okaya Electric Industries RSPD series
The MR-JN servo amplifiers are not intended to be used with low-voltage distribution lines for household. If it is
used in such an environment, radio frequency interference may be generated. 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)
MITSUBISHI ELECTRIC EUROPE B.V. hereby declares that the servo amplifiers are in compliance with EC
directives (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.
2.3.3 USA/Canada compliance
This servo amplifier is designed in compliance with UL 508C and CSA C22.2 No. 274.
(1) Installation
The minimum cabinet size is 150% of the MR-JN servo amplifier's volume. Also, design the cabinet so that the
ambient temperature in the cabinet is 55 °C or less. The servo amplifier must be installed in a metal cabinet.
Additionally, mount the servo amplifier on a cabinet that the protective earth based on the standard of IEC/EN
60204-1 is correctly connected. For environment, the units should be used in open type (UL 50) and overvoltage
category shown in table in section 8.1. The servo amplifier needs to be installed at or below pollution degree 2. For
connection, use only copper wires.
(2) Short-circuit current rating (SCCR)
Suitable For Use On A Circuit Capable Of Delivering Not More Than 100 kA rms Symmetrical Amperes, 500 Volts
Maximum.
(3) Branch circuit protection
For installation in the United States, branch circuit protection must be provided, in accordance with the National
Electrical Code and any applicable local codes.
For installation in Canada, branch circuit protection must be provided, in accordance with the Canada Electrical
Code and any applicable provincial codes.
