INFORMATION
The following descriptions do not substitute reading the manufacturer documentation.
⇨ Before using the voltage indicators, read the manufacturer documentation. The
manufacturer documentation is considered as leading.
INFORMATION
In adverse light conditions, shield the display of the voltage indicator or illuminate it
additionally.
Use
Voltage indicators type HR or LRM are used for verification of safe isolation from supply on
capacitive HR or LRM interfaces according to IEC 61243-5. There, the voltage indicator is the
mobile part of a voltage detecting system.
▪ The "voltage present" indication is ensured within the specified operating temperature in the
voltage range of the interface according to IEC 61243-5 Table 1.
▪ Voltage indicators can be used indoors and outdoors.
▪ Store and transport voltage indicators in dry and clean condition.
Maintenance
Voltage indicators do not contain any parts replaceable by the user, and they are maintenance-
free.
