Installation / Commissioning
These devices may only be installed, connected and operated by trained and qualified staff. Qualified staff must have knowledge of protection
classes, directives and regulations concerning electrical equipment designed for use in explosion hazardous areas and if necessary, of the regu-
lations applicable to safety-related systems.
Please verify that the classification and the marking on the device comply with the actual application conditions.
Installation and mounting instructions
Avoid static charging of cables and plastic devices. Please only clean the device with a damp cloth. Do not install the device in a dust flow and
avoid build-up of dust deposits on the device.
Special conditions for safe operation
Special conditions indicated with the X in the approval should be observed to ensure safe operation.
In hazardous areas tags may be read or written only with devices that are approved for this area.
In order to observe the admissible surface temperature of the data carriers, the strength of allowed electromagnetic fields should be limited.
Maximum values should comply with the safety and occupational health regulations. The regulation BGV B11 of the BGFE for electromagnetic
fields is applied in Germany.
The data carriers should not be damaged when mounted or dismounted. Please also ensure that the label is clearly visible for later inspection
when mounted. To avoid possible electrostatic discharge, 50 mm Ø data carriers should be mounted with only one freely accessible side. Due to
possible electrostatic discharge, all mounting screws and brackets for data carriers should be earthed safely when applied in the hazardous dust
explosive area. If this is not possible, because the data carrier is mobile for example, use plastic screws and brackets.
In hazardous dust explosive areas metal screws and brackets for tags have to be earthed safely. Static charge caused by cleaning, friction or
other forms of charge separation has to be avoided.
Tags approved for the temperature classes T6 (-45 °C…+55 °C ) and T4 (-45 °C…+85°C ) may be used in gas hazardous areas. The tags may
be used in hazardous dust explosive areas at ambient temperatures of -45 °C to +85 °C.
service / maintenance
Servicing is not required. Defective data carriers have to be replaced, repair is not possible. Mechanically damaged data carriers must be re-
moved.
