2 Safety
Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury or
death, if not avoided.
Information
... points out useful tips, recommendations and information for efficient and troublefree operation.
DANGER!
...identifies hazards caused by electric power. Should the safety instructions not be
observed, there is a risk of serious or fatal injury.
2 Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
instrument has been selected in terms of measuring range, design and specific
measuring conditions.
Non-observance can result in serious injury and/or damage to equipment.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The attachable indicator A-AI-2 is used for attaching between a transmitter and the according angular
plug.
The instrument has been designed and built solely for the intended use described here, and may only
be used accordingly.
If the instrument is transported from a cold into a warm environment, the formation of condensation
may result in the instrument malfunctioning. Before putting it back into operation, wait for the
instrument temperature and the room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

2 Safety
This device was designed and tested considering the safety regulations for electronic measuring
devices.
Faultless operation and reliability in operation of the measuring device can only be assured if the
General Safety Measures and the devices specific safety regulation, mentioned in this operating
instructions, are considered.
1. Faultless operati on and reliability in operation of the measuring device can only be assured if
the device is used within the climatic conditions specified in the chapter “Specifications“.
2. Always disconnect th e device from its supply befo re opening it. Take care that nobody can
touch any of the unit‘s contacts after installing the device.
3. Standard regulations for operation and safety for electrical, light and heavy current equipment
have to be observed, with particular attention paid to the national safety regulations (e.g. VDE
0100).
4. When connecting the device to other devices (e.g. the PC) the interconnection has to be
designed most thoroughly, as internal connections in third-party devices (e.g. connection of
ground with protective earth) may lead to unwanted voltage potentials.
5. The device must be switched off and must be marked against using again, in case of obvious
malfunct i o ns of the de vi ce whi c h are e.g.:
visible damage
no prescripted working of the de vice
storing the device under inappropriate conditions for longer time
When not sure, the device should be s ent to the manufacturer for repairing or servicing.
6. In case of connecting lines lon ger than 30 m or in case of lines leaving the buildi ng an
additional suitable overvoltage protection shall be provided.
