APPENDIX
(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 an earth-leakage current breaker, always ground the protective earth (PE) terminal of the
servo amplifier to prevent an electric shock. Only an RCD (earth-leakage current breaker) of type B
can be used for the power supply side of the product.
(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 IEC/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), connect them to a shielded grounding. Use an EMC filter and surge protector on the primary
side. The following shows recommended products.
EMC filter: Soshin Electric HF3000A-UN series
Surge protector: Okaya Electric Industries RSPD-250-U4 series
- 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.
(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 each MR-J4 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. For environment, the units should be used in open type (UL 50) and overvoltage
category III or lower. The servo amplifier needs to be installed at or below of pollution degree 2. For
connection, use only 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-J4 servo amplifiers have servo motor overload protective function. (It is set on the basis (full
load current) of 120% rated current of the servo amplifier.)
