2 Safety
2.1 General safety guidelines
Please note the following general safety guidelines:
}Ensure VDE, local and national regulations are met, especially those relating to safety.
The relevant safety regulations for the respective application must also be met.
}The product is designed exclusively for use in an industrial environment. It is not suit-
able for use in a domestic environment, as this can lead to interference. Additional sup-
pression measures may be required.
}The deciding factors in how to use the device are the requirements of the relevant certi-
fication body (e.g. BG or TÜV).
}In particular please observe the wiring regulations.
}If the devices are altered in any way, such as exchanging a component or carrying out
soldering work, the guarantee, and any approval, will be rendered invalid.
}Devices must be disposed of properly when they reach the end of their service life.
2.2 Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
A competent person is someone who, because of their training, experience and current pro-
fessional activity, has the specialist knowledge required to test, assess and operate the
work equipment, devices, systems, plant and machinery in accordance with the general
standards and guidelines for safety technology.
It is the company’s responsibility only to employ personnel who:
}Are familiar with the basic regulations concerning health and safety / accident preven-
tion
}Have read and understood the information provided in this description under "Safety"
}And have a good knowledge of the generic and specialist standards applicable to the
specific application.
2.3 Safety during installation
2.3.1 Power supply
The control system requires a 24 VDC supply. Check that the external power supply
provides this voltage.
The tolerance of the supply voltage must comply with the technical details. Safe operation
cannot be guaranteed outside this range.
Protect the external power supply by fitting a fuse between the external power supply and
the control system. The size of the fuse will depend on the specification of the external
power supply, the cable cross section and on local regulations.

Safety
Installation Manual PNOZmulti Installation Manual
1002265-EN-02 8
WARNING!
Risk of electrocution!
Safe electrical isolation must be ensured for the external power supply that
generates the supply voltage. Failure to do so could result in electric shock.
The power supplies must comply with EN 60950-1:2006/A11:2009, EN
61558-2-6:11/1997.
WARNING!
Risk of electrocution!
When voltage is applied, contact with live components could result in seri-
ous or even fatal injury from an electric shock.
If voltages higher than 50VAC or 120VDC are connected to the control
systems PNOZmulti or PNOZmulti Mini, e.g. to switch contacts on relay
modules, please note the following:
– Specific accident prevention regulations apply.
2.3.2 Installation
Please note:
}The control systems should be installed in an enclosure, e.g. control cabinet.
}The control cabinet must conform to the protection class required for the environment.
}Please refer to the technical details of the relevant devices when installing them in the
control cabinet.
}Ensure there is sufficient ventilation to prevent heat building up within the control cab-
inet. Monitor the ambient temperature of 0...60 °C.
}In extreme ambient conditions, additional measures such as control cabinet air condi-
tioning may be required in order to keep within the prescribed value range.
2.3.3 Chip card
The base units for the PNOZmulti and PNOZmulti Mini and the base units PNOZ m B0 from
the PNOZmulti 2 range have a chip card for saving and downloading projects.
NOTICE
The chip card contact is only guaranteed if the contact surface is clean and
undamaged. For this reason please protect the chip card's contact surface
from
– Contamination
– Contact
– Mechanical impact, such as scratches.

Electromagnetic compatibility (EMC)

3 Electromagnetic compatibility (EMC)
3.1 Overview
The PNOZmulti systems are designed for use within an electromagnetic industrial environ-
ment. To ensure electromagnetic compatibility the correct procedures must be carried out
during installation.
A device is electromagnetically compatible if
}It functions without error in a given electromagnetic environment.
}It does not adversely affect its own environment.
Electromagnetic interference can reach the devices through:
}Fields
}Power supplies
}Earth cabling
}Bus connections
}Interfaces
}Input and output cables
The interference can be transferred from the source to the receiver (interference sink) via
the coupling routes.
Interference reaches the interference sink (e.g. the control system devices) in various ways:
}DC coupling:
DC coupling occurs if the source and sink of interference have common cable connec-
tions. The common cable presents complex resistances, inducing potential differences.
– Typical sources of interference are switches/relays, running motors or varying po-
tentials for other systems on the same power supply.
}Capacitive (electrical) coupling
A different potential between the source and interference sink (e.g. two cables) creates
an electrical field. Coupling is proportional to the rate of voltage change.
– Typical sources of interference are contactors, static discharge, parallel signal
cables.
}Inductive (magnetic) coupling
A live cable produces a magnetic field which also surrounds adjacent cables. Interfer-
ence voltage is induced. Coupling is proportional to the rate of current change.
– Typical sources of interference are mains cables running in parallel, live cables,
high frequency cables, inductors, transformers, motors.
}Electromagnetic coupling
A cable can emit a signal as a radio wave. This wave is then picked up by another
cable.
– Typical sources of interference are transmitters such as radios, sparks from spark
plugs, welding equipment, etc.
