1.2 Requirements for conpliance with the Low Voltage Directive
The Low Voltage Directive is mandatory within Europe, effective 1st January
1997.
The Low Voltage Directive requires each device which operates with power
supply ranging from 50VAC to 1000V and 75VDC to 1500V to satisfy
necessary safety items.
In the Sections from 1.2.1 to 1.2.5, cautions on installation and wiring of the
GOT to conform to the Low Voltage Directive requires are described.
We have put the maximum effort to develop this material based on the
requirements and standards of the Directive that we have collected.
However, compatibility of the devices which are fabricated according to the
contents of this manual to the above Directive is not guaranteed. Each
manufacturer who fabricates such device should make the final judgement
about the application method of the Low Voltage Directive and the product
compatibility.
1.2.1 Standard subject to GOT
The standard subject to GOT is EN61010-1 safety of devices used in
measurement rooms, control rooms, or laboratories.
1.2.2 Power supply
The insulation specification of the GOT was designed assuming installation
category II. Be sure to use the installation category II power supply to the
GOT.
The installation category indicates the durability level against surge voltage
generated by lightning strike. Category I has the lowest durability; category
IV has the highest durability.
Category IV
Category II indicates a power supply whose voltage has been reduced by two
or more levels of isolating transformers from the public power distribution.
Category III
Category II
Installation Category
5
Category I
