Local Grounding the Bus: General

Introduction

The bus can be grounded in three different ways:

Connect the shield to the local ground and to the two ends of the cable.
Connect the shield to the local ground at one end and to the local ground via a surge suppressor at the other end.
Connect the shielding to the local ground at one end and isolating it from the ground at the other end.

Principle

Opposite each main cable path, a copper pad grounds the cable shields:

The path (20 in the following diagram) locally grounds the cable shielding.
The path (18 in the following diagram) locally grounds the cable shielding via a surge suppressor.

Illustration

This diagram shows the principle for locally grounding the device as a whole.

Cable Preparation Template: Introduction

Certain precautions must be taken in order to ensure correct placement of the bus cables:

Follow the stripping template.
Use the following cable ends:
- DZ5-CE005 for the main cables
- DZ5-CE007 for the power supply cable

This diagram shows the local grounding principle for the device as a whole.
