Safety Instructions
2.3 Applicable standards and directives for
installation and operation
The devices of the ABB EDS500 series are produced in compliance with the relevant
regulations and standards.
According to IEC 60664-1 (DIN VDE 0110-1) Insulation coordination for equipment within low-
voltage systems – Part 1: Principles, requirements and tests, classification of the EDS500
series is as follows:
•
Pollution degree 2
Only non-conductive pollution occurs except that occasionally a temporary conductivity
caused by condensation is to be expected.
•
Overvoltage category II
in accordance with the definitions in IEC 60364-4-44
The owner of the devices and components is responsible to ensure that they are installed
safely and in compliance with the applicable local laws and regulations.
Standard Explanation

Protection against electric shock - Protection against unin-
tentional direct contact with hazardous live parts
IEC/EN 60204 (DIN VDE 0113) Safety of machinery; Electrical equipment of machines
Part 1: General requirements
EN 50178 (DIN VDE 0160) Electronic equipment for use in electrical power installations
and their assembly into electrical power installations
EN 50310 (DIN VDE

ings with information technology equipment
Table 3: Standards
If the "Pollution degree 2" classification according to DIN VDE 0110 cannot be guaranteed or if
further protection against direct contact is required, mount the devices into suitable cubicles.
If devices of the EDS500 series are coupled with or supplied through power-frequency
voltage networks of overvoltage category III, take suitable protective action, such as
installing surge voltage protectors, to guarantee that overvoltage category II (1500 V max.
transient) according to DIN VDE 0110 applies at the terminal connectors. The secondary
circuit should be connected to protective terminal.
