NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
3.2 System requirements

section for details of which versions of the base unit and PNOZmulti Configurator can be
used for this product.
3.3 Safety regulations
3.3.1 Safety assessment
Before using a device it is necessary to perform a safety assessment in accordance with
the Machinery Directive.

Safety
Operating Manual PNOZ m EF 8DI4DO
1002661-EN-05 | 10
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
3.3.2 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 prevention,
}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.
3.3.3 Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended,
}Damage can be attributed to not having followed the guidelines in the manual,
}Operating personnel are not suitably qualified,
}Any type of modification has been made (e.g. exchanging components on the PCB
boards, soldering work etc.).
3.3.4 Disposal
}In safety-related applications, please comply with the mission time TM in the safety-related
characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).
3.3.5 For your safety
The unit meets all the necessary conditions for safe operation. However, you should always
ensure that the following safety requirements are met:
}This operating manual only describes the basic functions of the unit. The expanded func-
tions are described in the PNOZmulti Configurator's online help. Only use these functions
once you have read and understood the documentations.
}Do not open the housing or make any unauthorised modifications.
}Please make sure you shut down the supply voltage when performing maintenance work
(e.g. exchanging contactors).

Function description
Operating Manual PNOZ m EF 8DI4DO
1002661-EN-05 | 11
4 Function description
4.1 Integrated protection mechanisms
The relay meets the following safety requirements:
}The circuit is redundant with built-in self-monitoring.
}The safety device remains effective in the case of a component failure.
}The safety outputs are tested periodically using a disconnection test.
4.2 Functions
The expansion module provides additional inputs and additional semiconductor outputs.
The function of the inputs and outputs on the control system depends on the safety circuit
created using the PNOZmulti Configurator. A removable data medium is used to download
the safety circuit to the base unit. The base unit has 2 microcontrollers that monitor each
other. They evaluate the input circuits on the base unit and expansion modules and switch
the outputs on the base unit and expansion modules accordingly.
The online help on the PNOZmulti Configurator contains descriptions of the operating
modes and all the functions of the PNOZmulti control system, plus connection examples.
4.3 System reaction time
Calculation of the maximum reaction time between an input switching off and a linked out-
put in the system switching off is described in the document "PNOZmulti System Expan-
sion".

5 Installation
5.1 General installation guidelines
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Fit the safety system to a horizontal mounting rail. The venting slots must face upward
and downward. Other mounting positions could damage the safety system.
}Use the locking elements on the rear of the unit to attach it to a mounting rail.
}In environments exposed to heavy vibration, the unit should be secured using a fixing ele-
ment (e.g. retaining bracket or end angle).
}Open the locking slide before lifting the unit from the mounting rail.
}To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
}The ambient temperature of the PNOZmulti units in the control cabinet must not exceed
the figure stated in the technical details. Air conditioning may otherwise be required.
NOTICE
Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Ensure against discharge
before touching the product, e.g. by touching an earthed, conductive sur-
face or by wearing an earthed armband.
