Safety Instructions
DS 400 V1.31 Page 7of 119
1.2 Installation
Warning!
Supply voltage!
Contact with supply voltage carrying non-
insulated parts may cause an electric shock
with injury and death.
Measures:
• Note all applicable regulations for electrical installations (e.g. VDE 0100)!
• Carry out maintenance only in strain less state!
• All electric works are only allowed to be carried out by authorized qualified personnel.
Danger!
Missing earth connection!
When the earth connection (protective earth) is missing, there is the
risk in the event of malfunction, that contactable, conductive
components may carry supply voltage. Touching of such parts leads
to an electric shock with injuries and death.
It is imperative to connect the plant to earth or to connect the
protective conductor according to the regulations.
Do not use plug adapters at the power plug.
Have the power plug replaced by qualified skilled persons,
if required.

Safety Instructions
DS 400 V1.31 Page 8of 119
The plug of the power supply cord is used as a separator. This separator must be clearly recognizable
and easily accessible by the user. A plug connector with a CEE7/7 system is necessary.
All the electrical lines carrying supply voltage or another voltage that is dangerous in the case of con-
tact (power supply cord, alarm and indicator relays), must additionally be equipped with double or
reinforced insulation (EN 61010-1). This can be ensured by using plastic-sheathed cables, a second
insulation (e.g. flexible insulating tubing), or correspondingly suitable lines with reinforced insulation.
The connecting cables can be equipped, for example, with flexible insulating tubing.
The additional flexible insulating tubing must withstand the electrical and mechanical stresses that can
occur during the intended use (see EN 61010-1, Clause 6.7.2.2.1).
DANGER!
Supply voltage!
When wiring the connecting lead, it must be ensured that the double or
reinforced insulation be-tween the electric circuits that are dangerous in the
case of contact and the contactable secondary circuit remains maintained.
NOTE!
The additional insulation must be suitable for a test voltage of 1500 V
alternating current.
The thickness of the insulation must be at least 0.016 inch.
E.g. flexible insulating tubing, type BIS 85 (Bierther GmbH).
The additional insulation of the connecting leads (mains connection, alarm and indicator relays) can
be implemented as follows:
3 2 1
(1) - Terminals (connectors)
(2) – Flexible insulating tubing for the connecting leads
(3) – Connecting cable

Application Area / Intended use
DS 400 V1.31 Page 12 of 119
4 Application area
Our long-term hands-on experience in measurement and control technology was implemented in the
new DS 400.
From recording of the measured data, automatic sensor identification, indication on a big colour
screen, alerting, storage up to remote read-out via web server, all that is possible with DS 400. By
means of the CS-Soft, software alarms can be sent via SMS or e-mail.
On the big 3.5' colour screen with touch panel, all information is available at a glance.
The operation is very easy. All measured values, measured curves and threshold exceeding’s are
indicated. The progression of the curve, since the beginning of the measurement, can be viewed by
an easy slide of the finger.
The huge difference to ordinary paperless chart recorders reveals in the easy initiation as well as in
the evaluation of the measured data. All sensors are identified directly and powered by DS 400.
Everything is matched and tuned.

DANGER!
Supply voltage!
When wiring the connecting lead, it must be ensured that the double or
reinforced insulation be-tween the electric circuits that are dangerous in the
case of contact and the contactable secondary circuit remains maintained.
NOTE!
The additional insulation must be suitable for a test voltage of 1500 V
alternating current.
The thickness of the insulation must be at least 0.016 inch.
E.g. flexible insulating tubing, type BIS 85 (Bierther GmbH).
The additional insulation of the connecting leads (mains connection, alarm and indicator relays) can
be implemented as follows:
3 2 1
(1) - Terminals (connectors)
(2) – Flexible insulating tubing for the connecting leads
(3) – Connecting cable
NC and COM are connected at:
- alarm
- power failure
- sensor break
