4.2 Electrical installation

Destruction of parts of equipment and loss of regulation control,
unforeseen actions of the position indicator or other devices
The position indicator is protected against electromagnetic interference.
Excessive electromagnetic interference may cause unexpected behavior of
the position indicator (e. g., destruction of the position indicator; loss of
the position value).
` All supply lines for connecting the position indicator must be shielded.
` Perform wiring work in accordance with the EMC measures IEC 61326-1
and chapter 4.2.
` Check the correct execution of the EMC measures.
` Never wire or disconnect electrical connections while they are live.
` Perform wiring work in the de-energized state only.
` Use strands with suitable ferrules.
` Check all lines and plug connections before switching on the device.
Danger of fire
In order to avoid consequential damage in case of device defects the fol-
lowing fusing is recommended.
` The nominal current rating of a delay fuse must be adjusted to the
number of devices in the system (see chapter 9).
Basically, all connections are protected against external interference.
Choose a place of operation that excludes inductive or capacitive interfer-
ence influences on the position indicator. When mounting the system keep
a maximum possible distance from lines loaded with interference. If neces-
sary, provide additional installations including screening shields or metal-
lized housings. Contactor coils must be linked with spark suppression.
Connection concept
When operated together, multiple position indicators must be connected
to a common GND potential. For this purpose, the GND signal must always
be carried along in the bus wiring.
Potentially live contacts must be protected against touch. Therefore, take
care that the position indicator is connected via the "Bus On" connec-
tion (see Fig. 6). This ensures protection of the live contacts on "Bus Off"
by means of the jack (for the IP type of protection, please refer to chap-
ter 4.1).
