APPENDIX
(b) MR-J3W-22B to MR-J3W-1010B
The control circuit provide safe separation to the main circuit in the servo amplifier.
(3) Environment
(a) Operate the servo amplifier at pollution degree 2 or 1 set forth in EN 60664-1. For this purpose, install
the servo amplifier in a control box which is protected against water, oil, carbon, dust, dirt, etc. (IP54).
(b) Use the product under the following conditions.
(4) Power supply
(a) This servo amplifier can be supplied from star-connected supply with earthed neutral point of
overvoltage category III set forth in EN 60664-1. However, when using the neutral point of 400V
system for single phase supply, a reinforced insulating transformer is required in the power input
section.
(b) For the interface power supply, use a 24VDC power supply with reinforced insulation on I/O terminals.
(5) Grounding (except MR-J3W-0303BN6)
(a) To prevent an electric shock, the PE terminal (marked
the PE of the control box.
(b) Do not connect two ground cables to the same protective earth (PE) terminal. Always connect cables
to the terminals one-to-one.
