General wiring guidelines

The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
Information given in the
}
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.
The max. cable length between two link modules may be max. 1000 m.
}
Please note:
When connecting to a PNOZ ml1p with a version < 2.0, the cable length may be max.
100 m. The reduced cable length must be configured in the PNOZmulti Configurator.
Connect the inputs and outputs from two PNOZ ml1p with a 4-core shielded cable. The
}
cables must be twisted in pairs (see "Preparing for operation").
Note the crossover cabling, e.g. CA+ with CB+.
}
The cables must be classified into a minimum of Category 5 in accordance with ISO/
}
IEC 11801.
You can use ready-made cable from Pilz to connect two PNOZ ml1p. The plug-in con-
}
nection terminals are either designed as cage clamp terminals or screw terminals (see
order reference).

Technical details [
Please note: Always connect the shield to both link modules (Shield terminal).
The shield of the connection cable may only be connected to the Shield terminals
on both PNOZ ml1p. Do not connect the shield to the equipotential bonding bar, for
example.
CAUTION!
Only connect and disconnect the expansion module when the supply
voltage is switched off.
