The wiring is defined in the circuit diagram of the PNOZmulti
Configurator.
Note:
 Information given in the "Technical details" must be followed.
Funktionserde  External measures must be used to connect the FE terminal to the
function earth (e.g. mounting rail).
Verdrahtung_Netzteil_sichere_Trennung  The power supply must meet the regulations for extra low voltages
with safe separation.
Verdrahtung PNOZ ml2p  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 pre-assembled cable can be used to connect the decentralised
modules (see order reference).
 The plug-in connection terminals are either designed as cage clamp
terminals or screw terminals (see order reference).

6.1.1 Insulation voltage test
Insulation voltage test 6- Isolationsspannungsprüfung
The product PNOZ mml2p is connected to functional earth via pro-
tection elements on the supply voltage. Insulation voltage tests are only
possible with voltages up to ca. 42 V.
CAUTION!
Only connect and disconnect the expansion module when the
supply voltage is switched off.
