Installation Notes
Please read the following installation notes carefully to use the filter unit to
its option.
Mounting
Check the servo amplifier type.The filter should be used only in combina-
tion with servo amplfiers described in the table below.
햲
No foot print filter
Function
The filters described in this document are designed as foot print filters and
comply the european standards for drives with speed control.
The function of the filter is to reduce conducted noise voltages to comply
with the limits defined for Environment 1.
The Filters can provide conformity with the limits for Environment 1 (unre
-
stricted distribution/category C1) with motor cable lengths up to 20 m
(shielded) and for Environment 1 (restricted distribution/category C2) with
motor cable lengths up to 50 m (shielded).
Mounting of filters
The filter and the according servo amplifier are mounted side by side on the
back of the cabinet. For correct filter performance the filter mounting bolts
should electrically bond to the cabinet back panel wich is connected to
earth. If this is not possible, the paint should be removed from the cabinet
directly under the filter footprint.
MR-J3-A쏔 and MR-J3-B쏔
For exact dimensions please refer to sheet ”Dimensions of the filters”.
Wiring
For electrical installation follow the wiring procedure shown in the picture
below. The maximum wiring lenght of the motor cable should be within the
specified values.
1 phase wiring
3 phase wiring
All cables must be earthed at both ends in order to reduce cable radiation.
Motor cables must be shielded cables. Earth motor, bond to filters.
For environmental conditions and mounting position please note the
instructions in the operation manual for the servo amplifier MR-J3-A or
MR-J3-B respectively.

CAUTION
쎲
The noise filter units described in this reference sheet are
designed exclusively for use with Mitsubishi servo amplifiers
types MR-J3-A and MR-J3-B.
쎲
These filters are necessary to comply with limits for conducted
noise voltages defined by the EN 61800-3: 2005 standard. The
filter units are suitable for complying with the limits for Envi
-
ronment 1 (category C1/unrestricted distribution) or (cate
-
gory C2/restricted distribution) depending on the length of the
motor cable. It is possible that you may experience different
results in practice, particularly if you do not completely and
correctly follow the accepted EMC procedures for proper
installation of filters and routing the power and control lines.
쎲
These filters are NOT designed for use in power networks (IT
type).
쎲
When the noise filters are operated leakage currents are dis-
charged to earth. This can trigger upstream protective devices
(as RCDs), particularly when there are unbalanced mains volt-
ages, mains phase failures or switching activities on the input
side of the filter.
쎲
The values of the power loss and leakage current in the follow-
ing tables are typical values in a steady and error-free state.
Depending on the power supply voltage, the power supply fre-
quency and the filter used they may vary slightly.
쎲
Please note, that the appearance and wiring mechanics of the
noise filters may differ from the figures shown in this short ref-
erence. Safe functioning as well as the grade of the radio fre-
quency protection do not take affect of this.

CAUTION
쎲
The cables of the input and output of the filter and of the servo
amplifier respectively should be layed with a great distance to
each other.
쎲
The power supply 24 V DC for the control inputs of the servo
amplifier should be filtered separately.
쎲
If the leakage current is higher than 3,5 mA, the filter must be
wired with a fixed protective earth (PE) connection according
to EN 50178.
