1 Safety guidelines
Read carefully the safety guidelines and programming instructions contained in
this manual before connecting/using the device.
Disconnect power supply before proceeding to hardware settings or electrical
wirings to avoid risk of electric shock, re, malfunction.
Do not install/operate the device in environments with ammable/explosive
gases.
This device has been designed and conceived for industrial environments and
applications that rely on proper safety conditions in accordance with national
and international regulations on labour and personal safety. Any application
that might lead to serious physical damage/ life risk or involve medical life
support devices should be avoided.
Device is not conceived for applications related to nuclear power plants,
weapon systems, ight control, mass transportation systems.
Only qualied personnel should be allowed to use device and/or service it and
only in accordance to technical data listed in this manual.
Do not dismantle/modify/repair any internal component.
Device must be installed and can operate only within the allowed environmental
conditions. Overheating may lead to risk of re and can shorten the lifecycle of
electronic components.
1.1 Organization of safety notices
Safety notices in this manual are organized as follows:
Safety notices Description
Danger! Disregarding these safety guidelines and notices can be
life-threatening.
Warning! Disregarding these safety guidelines and notices can result
in severe injury or substantial damage to property.
Information! This information is important for preventing errors.

1.2 Safety Precautions
This product is classied as front panel process control equipment Danger!
If the output relays are used past their life expectancy, contact
fusing or burning may occasionally occur.
Always consider the application conditions and use the output
relays within their rated load and electrical life expectancy. The life
expectancy of output relays varies considerably with the output
load and switching conditions.
Danger!
A malfunction in the Digital Controller may occasionally make
control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the event
of malfunction of the Digital Controller, take appropriate safety
measures, such as installing a monitoring device on a separate
line.
Warning!
1.3 Precautions for safe use
Be sure to observe the following precautions to prevent operation failure,
malfunction, or adverse aects on the performance and functions of the
product. Not doing so may occasionally result in unexpected events. Do not
handle the Digital Controller in ways that exceed the ratings.
• The product is designed for indoor use only. Do not use or store the product
outdoors or in any of the following places.
- Places directly subject to heat radiated from heating equipment.
- Places subject to splashing liquid or oil atmosphere.
- Places subject to direct sunlight.
- Places subject to dust or corrosive gas (in particular, sulde gas and
ammonia gas).
- Places subject to intense temperature change.
- Places subject to icing and condensation.
- Places subject to vibration and large shocks
• Installing two or more controllers in close proximity might lead to increased
internal temperature and this might shorten the life cycle of electronic
components. It is strongly recommended to install cooling fans or other
air-conditioning devices inside the control cabinet.
• Always check the terminal names and polarity and be sure to wire properly.
Do not wire the terminals that are not used.
• To avoid inductive noise, keep the controller wiring away from power cables
that carry high voltages or large currents. Also, do not wire powerlines

User manual - ZTA9648O - 7
together with or parallel to Digital Controller wiring. Using shielded
cables and using separate conduits or ducts is recommended. Attach a
surge suppressor or noise lter to peripheral devices that generate noise
(in particular motors, transformers, solenoids, magnetic coils or other
equipment that have an inductance component). When a noise lter is used
at the power supply, rst check the voltage or current, and attach the noise
lter as close as possible to the Digital Controller. Allow as much space as
possible between the Digital Controller and devices that generate powerful
high frequencies (high-frequency welders, high-frequency sewing
machines, etc.) or surge.
• A switch or circuit breaker must be provided close to device. The switch
or circuit breaker must be within easy reach of the operator, and must be
marked as a disconnecting means for the controller.
• The device must be protected by a fuse 1A (cl. 9.6.2)
• Wipe o any dirt from the Digital Controller with a soft dry cloth. Never
use thinners, benzine, alcohol, or any cleaners that contain these or other
organic solvents. Deformation or discoloration may occur.
• The number of non-volatile memory write operations is limited. Therefore,
use EEprom write mode when frequently overwriting data, e.g.: through
communications.
• Chemicals/solvents, cleaning agents and other liquids must not be used.
• Non-respect of these instructions may reduce performances and safety of
the devices and cause danger for people and property.
1.4 Environmental policy and waste disposal/ WEEE
Do not dispose electric tools together with household waste material.
According to European Directive 2012/19/EU on waste electrical and electronic
equipment and its implementation in accordance with national law, electric
tools that have reached end of life must be collected separately and returned to
an environmentally compatible recycling facility.
