tion of safety circuits and are designed for use in:
}E-STOP equipment
}Safety circuits in accordance with VDE0113 Part 1 and EN60204-1
The following is deemed improper use in particular
}Any component, technical or electrical modification to the product,
}Use of the product outside the areas described in this manual,
}Use of the product outside the technical details (see Technical details [ 18]).
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 Safety regulations
3.2.1 Safety assessment
Before using a device it is necessary to perform a safety assessment in accordance with
the Machinery Directive.
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.
3.2.2 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.

Safety
Operating Manual PNOZ mo3p
21134-EN-07 | 10

}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.
3.2.3 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.).
3.2.4 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).
3.2.5 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).
3.3 System requirements

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 semiconductor outputs.
The function of the outputs on the safety system depends on the safety circuit created us-
ing the PNOZmulti Configurator. A chip card 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 safety system, plus connection examples.

5 Installation
5.1 General installation guidelines
}The control system should be installed in a control cabinet with a protection type of at
least IP54. Fit the control system to a horizontal mounting rail. The venting slots must
face upward and downward. Other mounting positions could destroy the control system.
}Use the locking elements on the rear of the unit to attach it to a mounting rail. Connect
the control system to the mounting rail in an upright position, so that the earthing springs
on the control system are pressed on to the mounting rail.
}The ambient temperature of the devices in the control cabinet must not exceed the figure
stated in the technical details. Air conditioning may otherwise be required.
}To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
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.

5.3 Connecting the base unit and expansion modules
Connect the base unit and the expansion modules as described in the operating manuals
for the base modules.
}The terminator must be fitted to the last expansion module
}Install the expansion module in the position configured in the PNOZmulti Configurator.
The position of the expansion modules is defined in the PNOZmulti Configurator. The ex-
pansion modules are connected to the left or right of the base unit, depending on the type.
Please refer to the document "PNOZmulti System Expansion" for details of the number of
modules that can be connected to the base unit and the module types.

Commissioning
Operating Manual PNOZ mo3p

6 Commissioning
6.1 General wiring guidelines
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
}Information given in the Technical details [ 18] must be followed.
}The position of the expansion module is specified in the Hardware configuration of the
PNOZmulti Configurator.
}Use copper wiring with a temperature stability of 75 °C.
}Two connection terminals are available for each of the supply connections 24 V and 0 V
(semiconductor outputs), plus A1 and A2 (power supply). This means that the supply
voltage can be looped through several connections. When the supply voltage is looped,
the current at each terminal may not exceed 3A.
}Please note: The supply voltage always must be present at X2, even if you do not use the
semiconductor outputs.
The unit has 2 dual-pole semiconductor outputs. These may be configured as single or re-
dundant outputs. The output assignment is defined in the PNOZmulti Configurator. Wire the
output circuit as described in the table.
NOTICE
A resistance greater than 3 kOhm at the outputs is detected as an open cir-
cuit. On the following base units, only the outputs configured in the
PNOZmulti Configurator are tested:
– PNOZ m1p (coated version) from Version 5.0, PNOZ m0p, PNOZ
m2p from Version 2.0.
– On earlier versions of the base units, unused outputs must be loaded
with a resistance of less than 3 kOhm. Example: R = 2.7 kOhm, 0.3
W at 24 V.
