These frequency inverters meet the requirements of Low Voltage Directive 2014/35/EU and the requirements of
EMC Directive 2004/108/EC. EMC product standard EN 61800-3 refers to the drive system. The documentation
includes information on how to meet the requirements of the relevant standards if the frequency inverter is a
component of the drive system. The declaration of conformity must be supplied by the company that installs the
drive system.
6.5.4 Modified connection assignment for Dedrive Compact STO units compared to previous equipment
without STO
CAUTION
Modified connection assignment
Drive not functioning due to missing release
Dedrive Compact STO DIC-x-xxx-X-0000-x3 inverters have a different assignment for the X210B.2 control termi‐
nal compared to the previous DIC-x-xxx-X-0000-x0 and DIC-x-xxx-X-0000-x1 models. The STO A and STO B
signals must be connected in parallel for replacement units.
If STO A and STO B are to be connected by a separate 2-channel connection, refer to the information provided
in the "DIC Safe Torque Off operating instructions", see  Tab. 1, Page 2.
Line connection (A): provided the maximum permissible voltage drop
is considered, the power supply line can be of any length, but it must be
laid separately from control, data and motor cables. We recommend
screened cables be fitted between the line filter and the frequency in‐
verter if an external line filter is used. The screen of any control cables
must be connected to earth on both sides with good conductivity over a
large area using screen clamps (360° earth connection).
DC link connection (B): for link connections, the frequency inverters
must be connected with the same line potential or to a common DC
supply.
Control connection (C): ensure that EMC requirements are met,
particularly when control and signal cables are laid. The control and
signal cables must be laid separately from the power cables. The
screen of any control and signal cables must be connected to earth on
both sides with good conductivity over a large area using screen
clamps (360° earth connection). The screen of analogue signal cables
must be connected to earth at one end with the inverter.
Motor and braking resistor (D): the shielded motor cable must be
connected to the motor and braking resistor with a metal screw fitting
and to the frequency inverter with a suitable and highly conductive clip
(360° earth connection) with earth. The signal cable to monitor the mo‐
tor temperature must be laid separately from the motor cable.
