Introduction

Electrification is a technology that increases power density and improves mechanical flexibility and adaptability. It improves efficiency, enhances power transmission

Items improve fuel economy to meet user interests.

While agricultural machinery electrical systems have traditionally been powered by 12V DC, electrification can be typically only used in industrial/construction applications and other transportation

High voltages in the sector are introduced into the agricultural machinery and mobile equipment sector. In this new environment, voltage increases require special safety considerations.

The purpose of this document is to provide guidance for the safety of electrical systems on agricultural machinery and tractors (voltage range 50VAC~1000VAC

and 75VDC~1500VDC).

In addition, this document defines the electrical equipment requirements applicable to agricultural tractors and machinery.

Example scopes include but are not limited to the following.

--- Protection against electric shock;

--- Conventional wiring;

--- warning signs - safety signs;

---Precautions in the instruction manual.

This document supports electrical equipment standards such as IEC 60204-1 and ISO 6469.Other parts of this document are expected to deal with external machines

This document is a Type C standard as defined in ISO 12100.

When the requirements of Category C standards are different from those of Category A or B standards, the machines designed and manufactured according to the requirements of Category C standards shall be

Standard requirements take precedence over other standard requirements.

GB/T 41678 aims to establish the safety of high-voltage electrical and electronic components and systems related to agricultural machinery and tractors.
