• Grounding
To prevent an electric shock, always connect the protective earth (PE) terminal (marked
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.
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 product.
The MR-J4-700_4 is high protective earthing conductor current equipment, the minimum size of the protective earthing
conductor must comply with the local safety regulations.

■EU compliance
The MR-J4 servo amplifiers are designed to comply with the following directions to meet requirements for mounting, using,
and periodic technical inspections: Machinery directive (2006/42/EC), EMC directive (2014/30/EU), Low voltage directive
(2014/35/EU), and RoHS directive (2011/65/EU).
• EMC requirement
MR-J4 servo amplifiers comply with category C3 in accordance with EN 61800-3. As for I/O wires (max. length 10 m.
However, 3 m for STO cable for CN8.) and encoder cables (max. length 50 m), use shielded wires and ground the shields.
Install an EMC filter and surge protector on the primary side for input and output of 200 V class and for output of 400 V class
servo amplifiers. In addition, use a line noise filter for outputs of the 11 kW and 15 kW of 400 V class servo amplifiers. The
following shows recommended products.
EMC filter: Soshin Electric HF3000A-UN series, TF3000C-TX series, COSEL FTB series
Surge protector: Okaya Electric Industries RSPD series
Line noise filter: Mitsubishi Electric FR-BLF
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.
Use the DC power supply installed with the amplifiers in the same cabinet. Do not connect the other electric devices to the DC
power supply.
• For Declaration of Conformity (DoC)
Hereby, MITSUBISHI ELECTRIC EUROPE B.V. declares that the servo amplifiers are in compliance with the necessary
requirements and standards (2006/42/EC, 2014/30/EU, 2014/35/EU, and 2011/65/EU). For the copy of Declaration of
Conformity, contact your local sales office.
■USA/Canada compliance
This servo amplifier is designed in compliance with UL 508C and CSA C22.2 No. 14.
• Installation
The minimum cabinet size is 150% of each MR-J4 servo amplifier's volume. Also, design the cabinet so that the ambient
temperature in the cabinet is 55  or less. The servo amplifier must be installed in the 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 the following table.
