GerneralWarning!
This modul is designed for connection to hazardous electricvoltages. Ignoring this
warning can result in severe personalinjury or mechanical damage. To avoid the risk
of electric shock and fire, the safety instructions of this manual mustbe observed and
the guidelines followed. The specificationsmust not be exceeded, and the module
must only be appliedas described in the following. Prior to the commissioning of
the module, this manual must be examined carefully. Onlyqualified personnel
(technicians) should install this module.If the equipment is used in a manner not
specified by themanufacturer, the protection provided by the equipment
may be impaired.
Harzadous Voltage Warning!
Until the module is fixed, do not connect hazardousvoltages to the module.
The following operations should only be carried out on adisconnected
module and under ESD safe conditions:
troubleshooting the module.
Repair of the module must be done by Sensortherm GmbH only.
Symbol identification:
Triangle with an exclamation mark: Warning / demand.
Potentially lethal situations.
The CE mark proves the compliance of the module with the essential
requirements of the directives.

Safety instructions:
Definitions:
Hazardous voltages have been defined as the ranges: 75 to 1500 Volt
DC, and 50 to 1000 Volt AC.
Technicians are qualified persons educated or trained to mount,
operate and also troubleshoot technically correct and in accordance
with safety regulations. Operators, being familiar with the contents of
this manual, adjust and operate the knobs or potentiometers during
normal operation.
Receipt and unpacking:
Unpack the module without damaging it and make sure that the
manual always follows the module and is always available. The
packing should always follow the module until this has been
permanently mounted.
Check at the receipt of the module whether the type corresponds to the
one ordered.
Environment:
Avoid direct sunlight, dust, high temperatures, mechanical vibrations
and shock, as well as rain and heavy moisture. If necessary, heating in
excess of the stated limits for ambient temperatures should be avoided
by way of ventilation.
Al modules fall under Installation Category II, Pollution Degree I, and
Insulation Class II.
Mounting:
Only technicians who are familiar with the technical terms, warnings
and instruction in the manual and who are able to follow these should
connect the module.
Mounting and connection of the module should meet the national
Legal regulations for mounting of electric materials, i.a. wire cross section,
protective fuse and location. Descriptions of input/output and supply
connections are shown in the bloc diagram and side label.

Universal digital display AZ12

The following apply to fixed hazardous voltages-connected modules:
The max.size of the protective fuse is 10 A and, together with a
power switch, it should be easily accessible and close to the module.
The power switch should be marked with a label telling it switch off
the voltage to the module.
UL-installation requirements:
For use on a flat surface of a type 1 enclosure
use 60/75 °C cobber conductors only
Max. ambient temperature 60°C
Max. wire size, pins 41...46 AWG 30-16
Max. wire size, others AWG 30-12
UL file number E248256
Calibration and adjustment:
During calibration and adjustment, the measuring and connection of
external voltages must be carried out according to the specifications of
this manual. The technician must use tools and instruments that are
safe to use.
Normal operation:
Operators are only allowed to adjust and operate modules that are
safely fixed in panel, etc., thus avoiding the danger of personal injury
and damage. This means there is no electrical shock hazard, and the module is
easily accessible .

Universal digital display AZ12
7
Cleaning:
When disconnected, the module may be cleaned with a cloth
moistened with distilled water or ethyl alcohol.
Liability:
To the extent the instructions in this manual are not strictly observed,
the customer cannot advance a demand against Sensortherm GmbH that
would otherwise exist according to the concluded sales agreement.
