APPENDIX
(c) Power supply
This servo amplifier can be supplied from star-connected supply with grounded neutral point of
overvoltage category III set forth in IEC/EN 60664-1. 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.
(d) Grounding
To prevent an electric shock, always connect the protective earth (PE) terminal (marked
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.
(2) EU compliance
The MR-JE servo amplifiers are designed to comply with the following directions to meet requirements
for mounting, using, and periodic technical inspections: EMC directive (2004/108/EC), and Low-voltage
directive (2006/95/EC).
(a) EMC requirement
MR-JE servo amplifiers comply with category C3 in accordance 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. However, when the encoder cable length is longer than 30 m for MR-JE-70_ and MR-JE-
100_, set a radio noise filter (FR-BIF) to the input power supply side of the servo amplifier. The
following shows recommended products.
EMC filter: Soshin Electric HF3000A-UN series
Surge protector: Okaya Electric Industries RSPD-250-U4 series
Radio noise filter: Mitsubishi Electric FR-BIF
MR-JE 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 (2004/108/EC and 2006/95/EC). For the
copy of Declaration of Conformity, contact your local sales office.
