Using CE approved components will not guarantee a CE compliant system!

1.The components used in the drive, installation methods used, materials selected for interconnection of components are important.

2.The installation methods, interconnection materials, shielding, filtering and grounding of the system as a whole will determine CE compliance.

3.The responsibility of CE mark compliance rests entirely with the party who offers the end system for sale (such as an OEM or system integrator).

Baldor products which meet EMC directive requirements are indicated by a “CE” mark. A duly signed CE declaration of conformity is available from Baldor.

EMC Wiring Technique

Y

Capacitor

1CABINET

The drawing shows an electroplated zinc coated enclosure, connected to ground. This enclosure has the following advantages:

-All parts mounted on the back plane are connected to ground.

-All shield (screen) connections are connected to ground.

Within the cabinet there should be a spatial separation between power wiring (motor and AC power cables) and control wiring.

2SCREEN CONNECTIONS

All connections between components must use shielded cables. The cable shields must be connected to the enclosure. Use conductive clamps to ensure good ground connection. With this technique, a good ground shield can be achieved.

3EMC - FILTER

The EMI or main filter should be mounted next to the power supply (here BPS). For the connection to and from the main filter screened cables should be used. The cable screens should be connected to screen clamps on both sides. (Exception: Analog Command Signal).

4Grounding (Earth)

For safety reasons (VDE0160), all BALDOR components must be connected to ground with a separate wire. The diameter of the wire must be at minimum AWG#6 (10mm@). Ground connections (dashed lines) must be made from the central ground to the regen resistor enclosure and from the central ground to the Shared Power Supply.

5Y-CAPACITOR

The connection of the regeneration resistor can cause RFI (radio frequency interference) to be very high. To minimize RFI, a Y-capacitor is used. The capacitor should only be connected between the dynamic brake resistor housing and terminal pin R1 (lead from Lin).

Recommendation:

0,1∝ F / 250VAC Type: PME265

BALDOR-Ordering-No.: ASR27104
