App. - 6
(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.
(3) USA/Canada compliance
This servo amplifier is designed in compliance with UL 508C and CSA C22.2 No.14.
(a) Installation
The minimum cabinet size is 150% of MR-JE 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
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 table in section 8.1. The servo
amplifier needs to be installed at or below of pollution degree 2. For connection, use copper wires.
(b) 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.
(c) Overload protection characteristics
The MR-JE servo amplifiers have solid-state servo motor overload protection. (It is set on the basis
(full load current) of 120% rated current of the servo amplifier.)
