Please read the following safety instructions and the assembly chapter
2
before installation and
keep it for future reference.
Intended use
The device is intended for the evaluation and display of sensor signals.
In the event of improper use or operation personal injury and/or damage to
property may occur.
Control of the device
The devices are checked before shipment and shipped in perfect condition. If any damage is
visible on the device, we recommend a close inspection of the transport packaging. In case of
damage, please inform the supplier immediately.
Installation
The device may only be installed by a specialist with appropriate qualifications, such as an
industrial electronics technician or a specialist with comparable training.

Installation instructions
There must be no magnetic or electric fields in the immediate vicinity of the device, e.g. due to
transformers, two-way radios or electrostatic discharges. The fuse protection of the supply should
not exceed a value of
6A inert
.
• Do not install inductive loads (relays, solenoid valves, etc.) close to the device and suppress them
using RC spark quenching combinations or free-wheeling diodes.
• Lay input and output lines spatially separated from each other and not parallel to each other.
Route outgoing and return lines side by side. If possible, use twisted-pair cables. This will give
you the most accurate measurement results.
• If high accuracy is required and the measuring signal is small, the sensor leads must be shielded
and twisted. As a general rule, these must not be laid in the immediate vicinity of consumer
supply lines. In the case of shielding, this should only be connected on one side to a suitable
equipotential bonding (usually knife-edge ground).
• The device is not suitable for installation in explosive areas.
• An electrical connection deviating from the connection diagram can lead to danger to persons
and destruction of the device.
• The clamp area of the devices is part of the service area. Hier sind elektrostatische Entladungen
zu vermeiden. Dangerous body currents can occur in the clamp area due to high voltages, which
is why increased caution is required.
• Galvanically isolated potentials within a system must be connected to a suitable point (usually
earth or system ground). This results in lower interference sensitivity to radiated energy and
avoids dangerous potentials that can build up on long lines or be caused by faulty wiring.
