14. Safety advice
Please read the following safety advice and the assembly
chapter 6
before
installation and keep it for future reference.
Proper use
The
DAG-device
is designed for the evaluation and display of sensor signals.
Danger! Careless use or improper operation can result in
personal injury and/or damage to the equipment.
Control of the device
The panel meters are checked before dispatch and sent out in perfect condition.
Should there be any visible damage, we recommend close examination of the
packaging. Please inform the supplier immediately of any damage.
Installation
The
DAG-device
must be installed by a suitably
qualified specialist
(e.g. with a
qualification in industrial electronics).
Notes on installation
•
There must be no magnetic or electric fields in the vicinity of the device, e.g.
due to transformers, mobile phones or electrostatic discharge.
•
The
fuse rating
of the supply voltage should not exceed a value of
0.5 A N.B.
fuse
.
•
Do not install
inductive consumers
(relays, solenoid valves etc.) near the
device and
suppress
any interference with the aid of RC spark extinguishing
combinations or free- wheeling diodes.
•
Keep input, output and supply lines separate from each other and do not lay them
parallel with each other. Position “go” and “return lines” next to one another.
Where possible use twisted pair. So, the best measuring results can be received.
•
Screen off and twist sensor lines. Do not lay current-carrying lines in the
vicinity. Connect the
screening on one side
on a suitable potential equaliser
(normally signal ground).
•
The device is not suitable for installation in areas where there is a risk of
explosion.
•
Any electrical connection deviating from the connection diagram can
endanger human life and/or can destroy the equipment.
•
The terminal area of the devices is part of the service. Here electrostatic
discharge needs to be avoided. Attention! High voltages can cause dangerous
body currents.
