Appendix A
CE Compliance
Installation Requirements and Information
Certain practices must be followed when installing a TD servo drive or a TDC servo drive/controller in order to meet
the CE Electromagnetic Compatibility (EMC) Directive (89/336/EEC) and the Low Voltage Directive (73/23/EEC).
The TD family of products are components intended for installation within other electrical systems or machines. The
system or machine builder must ensure their system or end product complies with all applicable standards required for
that equipment, including overall CE certification. Following these practices will help ensure (but cannot guarantee)
that the machine in which these components are utilized will meet overall CE requirements.
Electromagnetic Compatibility Directive
In order to meet the various EMC Standards, all wiring must be done in accordance with the practices shown in Figure
1.
With the addition of a suitable ac line filter, such as Corcom part number 15ET1 (connected externally), the TD drive
and TDC drive/controller meet all the applicable EMC emission and immunity standards on a “stand-alone” basis:
EN55011, Class A:
for Radiated and Conducted Emissions
IEC1000-4-3:
for RF Radiated Immunity (RFRI)
IEC1000-4-4:
for Electrical Fast Transient Immunity (EFT)
IEC1000-4-6:
for RF Conducted Immunity (RFCI)
In order to achieve full CE compliance, an additional requirement must be met:
IEC1000-4-2:
for ESD Immunity
To meet this requirement, the TD or TDC must be placed inside a metal enclosure, as shown in Figure 1.
Low Voltage Directive
1) These drives are to be operated in a pollution degree 2 environment as described in standard EN50178.
2) All of the control inputs and outputs are isolated from the main input power with a “basic insulation rating”; e.g.,
their impulse withstand voltage capability is 2.5kV (1.2 / 50 us) as referenced in EN50178. Control inputs and outputs
may need another level of protection against direct contact if such protection is required by the standards governing
the overall system or machine and its intended operating environment. It is the machine-builder’s responsibility to
provide this protection, if needed.
3) For electrical safety, and to protect personnel against direct contact with live electrical parts, the terminal cover
(provided with the unit) MUST be installed over the AC input, motor output, and External REGEN terminals.
4) All cautions and warnings listed throughout the operators manual MUST be followed to insure safe system
operation.
