13. Safety advice
Please read the following safety advice and the assembly
chapter 5
before
installation and keep it for future reference
Proper use
The DAG-A…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-A…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 supress any interference with the aid of RC spark extinguishing
combinations or free-wheeling diodes.
 Keep input, output and supply lines separate from one another and do not lay
them parallel with each other. Position “go” and “return” lines next to one
another. Where possible use twisted pair. So, you receive best measuring
results.
 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 equalizer (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.
 Galvanic insulated potentials within one complex need to be placed on an
appropriate point (normally earth machines ground). So, a lower disturbance
sensibility against impacted energy can be reached and dangerous potentials, that
can occur on long lines or due to faulty wiring, can be avoided.
