Installing Your 1394 SERCOS Interface System 1-21
Mounting Your External
Shunt Resistor Kit
If your 1394 requires a means of dissipating regenerative energy that
exceeds the capacity of the shunt module, install an External Shunt
Resistor Kit (refer to Appendix C for catalog numbers).
To install your External Shunt Resistor Kit:
1. Layout the position for your shunt resistor in the enclosure (refer
to Establishing Noise Zones for panel layout recommendations).
2. Attach the shunt resistor to the cabinet. The recommended
mounting hardware is M6 metric (1/4 in.) bolts. Make sure all
fasteners are properly bonded to the subpanel. Refer to the
section HF Bonding Your System for proper bonding techniques.
3. Tighten all mounting fasteners.
For mounting dimensions, refer to the Motion Control Selection Guide
(publication GMC-SG001x-EN-P).
ATTENTION
!
To avoid the hazard of shock or burn and ignition of
flammable material, appropriate guarding must be
provided. These resistors can reach temperatures in
excess of 350° C (662° F). Install per local codes.
