Function description
} Dual-channel operation and supply voltage via PNOZsigma connector
} 3 safety contacts and 1 auxiliary contact each; these can be controlled separately
Installation
Connect the contact expansion block to the PNOZ s30 or base unit PNOZ mm0.1p/
PNOZmm0.2p
} Connect the contact expansion block using the connector supplied.
Control cabinet installation
} The safety relay should be installed in a control cabinet with a protection type of at least
IP54.
} Use the notch on the rear of the unit to attach it to a DIN rail.
} Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele-
ment (e.g. retaining bracket or an end angle).
Push the unit upwards or downwards before lifting it from the DIN rail.
Wiring
Please note:
} Information given in the "Technical details [ 804]" must be followed.
} The wiring guidelines in the base units' operating instructions must be taken into ac-
count.
} Outputs 13-14, 23-24, 33-34 are safety contacts; output 41-42 is an auxiliary contact
(e.g. for display).
} Auxiliary contact 41-42 shouldnot be used for safety circuits!
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 804]).
} Use copper wire that can withstand 60/75°C.
} Sufficient fuse protection must be provided on all output contacts with capacitive and in-
ductive loads.
} Ensure the wiring and EMC requirements of IEC 60204-1 are met.
} The power supply must comply with the regulations for extra low voltages with protect-
ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
