1.1 Meaning of Symbols and Markings
Caution - risk of danger & refer to instructions
Caution - risk of electric shock
Equipment protected by double or reinforced insulation (Class II)
Application around and removal from hazardous live conductors
is permitted.
>600V
Do not use in distribution systems with voltages higher than 680V.
Refers to the insulation resistance function.
CAT II
(Measurement Category II)

equipment connected directly to utilization points (socket outlets and
similar points) of the low-voltage MAINS installation.
CAT III
(Measurement Category III)
is applicable to test and measuring
equipment connected to the distribution part of the building’s low-
voltage MAINS installation.
CAT IV (Measurement Category IV)
is applicable to test and measuring
equipment connected at the source of the building’s low-voltage
MAINS installation.
