APPENDIX
(d) 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 a leakage circuit breaker, always ground the protective earth (PE) terminal of the servo
amplifier to prevent an electric shock. This product can cause a d.c. current in the protective earthing
conductor. Where a residual current-operated protective (RCD: earth-leakage current breaker)
device is used for protection in case of direct or indirect contact, only an RCD of Type B is allowed
on the supply side of this 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.
(2) 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
(2004/108/EC), and Low-voltage directive (2006/95/EC).
(a) 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. Use an EMC filter and surge protector on the primary
side for input of 200 V class and for input and 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
Surge protector: Okaya Electric Industries RSPD-250-U4 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.
(b) 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, 2004/108/EC and
2006/95/EC). For the copy of Declaration of Conformity, contact your local sales office.
