APPENDIX
App. - 12
(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 an earth-leakage current breaker, always ground the protective earth (PE) terminal of the
servo amplifier to prevent an electric shock. 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.

(2) EU compliance
The EC directives were issued to standardize the regulations of the EU countries and ensure smooth
distribution of safety-guaranteed products. The CE marking proves the compliance of the manufacturer
with the EC directives, and this marking also applies to machines and equipment incorporating servos.
(a) EMC requirement
MR-JN 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. The following shows recommended products.
EMC filter: Soshin Electric HF3000A-UN series
Surge protector: Okaya Electric Industries RSPD series
MR-JN servo amplifiers are not intended to be used on a low-voltage public network which supplies
domestic premises; Radio frequency interference is expected if it is 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.
(b) For Declaration of Conformity (DoC)
MITSUBISHI ELECTRIC EUROPE B.V. hereby declares that the servo amplifiers are in compliance
with EC directives (EMC directive (2014/30/EU), Low voltage directive (2014/35/EU), and RoHS
directive (2011/65/EU)). For the copy of Declaration of Conformity, contact your local sales office.
