CE COMPLIANCE
The DDC4 controller has been tested with a turret under the condition reported as follows and obtained the
compliance for: CEI EN 61800-2 and CEI EN 61800-3 + A11.
An external EMC filter (non supplied) is necessary for compliance whet DDC controller + turret are tested as
stand-alone component
The use in civil environment could generate disturbance to some electrical and electronic equipment and it
needs to provide additional solutions to avoid this effect.
The DDC4 controller, being transistorised drive for brushless motor, is not a safety device, and cannot work in
stand-alone mode because requires supply and wiring by the installer. So it is not subject to the CE mark
requirement.
By the way the CE mark is placed to show the compliance to the low-voltage directive about the electrical
safety of the component. The respect of EMC and general safety standard is in charge of the machine builder.
The instruction reported in this installation manual provide a line-guide to obtain the EMC compliance in
almost all applications.
