DS2100 User's Manual SECTION 2: SAFETY & EMC INSTRUCTIONS
PAGE 2-20 C27750-001
All external Regen (Regenerative circuit) resistors used with the DS2100 must be installed in conductive enclosures
which provide a degree of ingress protection against liquids and objects of at least IP22. Any paint on the panel or regen
resistor enclosure must be removed before the regen resistor enclosure is mounted.
Cables supplying external d.c. supply voltages to the DS2100 Servo-drive (For example, the 24 V
d.c.
supply) must be as
short as possible. The supply wires shall be twisted together or alternatively shielded cable shall be used. The 24 V
d.c.
supply should be routed as far from the motor power cable as possible to ensure EMC compliance.
Cables connecting the d.c. bus from the DS2100 Servo-drives must be as short as possible. Shielded cable shall be used.
Motor power cables MUST be shielded with the cable shield securely connected to Chassis Earth at both ends of the
cable. At the DS2100 end of the cable, the shield shall be earthed to Chassis Earth using the EMC kit or the panel earth
bar. The correct method to earth the shield is shown in Figure 2.2 Correct Cable Preparation Grounding of Shield to
Chassis
Figure 2.2 Correct Cable Preparation Grounding of Shield to Chassis
Motor resolver/signal cables must be shielded with the cable shield securely connected to Chassis Earth at both ends of
the cable.
Signal cables must be shielded with the cable shield securely connected to make a good HF earth bond to Chassis Earth
at both ends of the cable.
Typical cable shield terminations for each of the cables on each DS2100 size are shown in the following figures.
