6.1 Wiring
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
} Information given in the "Technical details" must be followed.
} Use copper wire that can withstand 75°C.
} External measures must be used to connect the FE terminal to the function earth (e.g.
mounting rail).
} The power supply must meet the regulations for extra low voltages with protective sep­
aration.
} 2 connection terminals are available for each of the supply connections 24 V and 0 V.
This means that the supply voltage can be looped through several connections. The
current at each terminal may not exceed 3 A.
} Please refer to the technical details for information on the maximum cable length.
Please also read the section entitled "Voltage drop".
} Shielded cable must be used from a cable length of 30 m.
} Pilz pre­assembled cable can be used to connect the decentralised modules (see order
reference).
} The plug­in connection terminals are either designed as cage clamp terminals or screw
terminals (see order reference).
CAUTION!
Only connect and disconnect the expansion module when the supply
voltage is switched off.
6.1.1 Insulation voltage test
The product PNOZ m EF PDP Link is connected to functional earth via protection ele­
ments on the supply voltage. Insulation voltage tests are only possible with voltages up to
ca. 42 V.
6.2 Preparing for operation
6.2.1 Download modified project to the PNOZmulti safety system
As soon as an additional expansion module has been connected to the system, the project
must be amended using the PNOZmulti Configurator. Proceed as described in the operat­
ing instructions for the base unit.
