ABB DSAI 160  DSAI160 CPU module

Filters and TPDs installed for noise

 suppression and transient protection must be directly grounded to the enclosures of the protected equipment. TPDs installed in distribution frames and junction boxes must be terminated directly to the ground bus or to the mounting enclosure.

The various communication

 The ground bus and the mounting enclosure must be bonded to the fault protection subsystem with minimum length conductors.Control circuits penetrating the CCA must be treated as BLACK1 conductors. They must be enclosed in continuous conduit, which are peripherally bonded at each end They must be powered from BLACK power

All penetrations through the CAA barrier

 must be thoroughly filtered. Both ends of shielded cable shall be terminated to case or enclosure. Continuous peripheral bonding of the shield is best.Filters and TPDs installed for noise suppression and transient protection must be directly grounded to the enclosures of the protected equipment. TPDs installed in distribution frames and junction boxes must be terminated

Application industry

 It is widely used in metallurgy, oil and gas, glass manufacturing, aluminum, petrochemical, coal mine, paper and printing, textile printing, machinery, electronic manufacturing, automobile manufacturing, tobacco, plastic machinery, electricity, water conservancy, water treatment/environmental protection, municipal engineering, boiler heating, energy, power transmission and distribution, etc.
