INFORMATION
This gives advice on applications and provides information on special fea-
tures.
Safety
Intended use
The PNOZ pe2p bus interface, together with an expansion module of the PNOZpower mod-
ular safety system, are used for the safety-related interruption of a safety circuit.
The bus interface consists of a
}Coupling plug with screw terminals for connecting to a master controller
}Terminator for terminating the PNOZpower bus
It is actuated by
}PNOZmulti range units,
}PSS range output modules,
}PNOZelog range units.
The bus interface may only be used in conjunction with units that evaluate a feedback loop.
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 [ 10]).
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.

Safety regulations
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.
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.).
Disposal
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).

Function Description
The bus interface PNOZ pe2p, in conjunction with the expansion modules, is used to ex-
pand a safety circuit. It is driven from a master controller (e.g. safe outputs on a PSS).
The unit is ready for operation when when supply voltage is applied and the feedback loop
Y1-Y2 is closed
}24 V DC are available at the terminal K1 (e.g. the PSS output has a high signal):
– At the expansion module control output connected to the PNOZpower bus there is a
high signal.
}0 V DC are available at the terminal K1 (e.g. the PSS output has a low signal):
– At the expansion module control output connected to the PNOZpower bus there is a
low signal.
NOTICE
When controlling an expansion module via the den PNOZpower bus the
switch-on delay/delay-on de-energisation of the controlling device and the
expansion module are added together.
Operating modes
}Single-channel operation: no redundancy in the input circuit, earth faults in the start cir-
cuit are detected depending on the master controller.

Installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Connect the bus interface to the first expansion module via the coupling connector.
NOTICE
Always fit a terminator to the first and last device.
}Only use terminators, jumpers and terminals of the modular safety system PNOZpower.
}Layout:
– The PNOZ pe2p is installed on the left of the first expansion module.
}Maximum hardware:
– 1 bus interface
– 6 expansion modules

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.
The plug-in connection terminals should only be connected and disconnec-
ted when the voltage is switched off.

Wiring
Please note:
}Information given in the "Technical details [ 10]" must be followed.
}Max. cable runs Imax at the input circuit and feedback loop: Short circuits and earth faults
are detected by the master controller. The maximum cable runs is therefore dependent
on the master controller.
}Use copper wire that can withstand 60/75°C.
}Ensure the EMC requirements of IEC 60204-1 are met.
}The bus interface and input circuits of the safety control system/ the safety relay must
always be supplied by a single power supply.
}The power supply must comply with the regulations for extra low voltages with protect-
ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
