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 [ 20] must be followed.
}
Use copper wire that can withstand 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 refer to the technical details for information on the maximum cable length.
Please also read the section entitled Voltage drop [ 17] .
} Shielded cable must be used from a cable length of 30 m.
} Pilz pre-assembled cable can be used to connect the decentralised modules (see Order
references [ 23] ).
}
The plug-in connection terminals are either designed as cage clamp terminals or screw
terminals (see Order references [ 23] ).
CAUTION!
Only connect and disconnect the expansion module when the supply
voltage is switched off.
6.1.1 Insulation voltage test
The product PNOZ ml2p is connected to functional earth via protection elements 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.
NOTICE
For the commissioning and after every program change, you must check
whether the safety devices are functioning correctly.
