Function Description
The power supply unit PNOZ pps1p supplies the base unit and the expansion modules of
the modular safety system PNOZpower with the required supply voltage. When operating
voltage is supplied the "POWER IN" LED will light. The "POWER OUT" LED will light when
the output voltage is correct. Depending on the plant state it is 19 V DC or 24 V DC. The
output voltage is fed to the terminals 0 V and +24 V for measuring purposes.
Installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Use the notches on the rear of the unit to attach it to a DIN rail.
}Fit the unit to a horizontal DIN rail. If other mounting positions are used, the switching
capability values stated in the technical details cannot be maintained.
}There are 2 sockets on the rear of the PNOZ pps1p.
The base unit/control module and the expansion modules are connected using the
jumpers supplied.
NOTICE
Always connect a terminator to the first and last device.

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.
}The output voltage can be measured at the terminals 0 V and +24 V.
}Do not connect external user to the terminals 0 V and +24 V!
}Connect terminal to the protective earth system.
}When the PNOZ pps1p power supply unit is used, the base unit draws power via the
PNOZpower bus. Do not connect an external supply voltage to terminals A1 and A2 of
the base unit!
}Use copper wire that can withstand 60/75°C.
}Ensure the wiring and EMC requirements of IEC 60204-1 are met.
