Installation
Install base unit without contact expansion module:
} Ensure that the plug terminator is inserted at the side of the unit.
Connect base unit and PNOZsigma contact expansion module:
} Remove the plug terminator at the side of the base unit and at the contact expansion
module.
} Connect the base unit and the contact expansion module to the supplied connector be-
fore mounting the units to the DIN rail.
Installation in control cabinet
} 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 (35mm).
} When installed vertically: Secure the unit by using a fixing element (e.g. retaining
bracket or end angle).
} Push the device upwards or downwards before lifting it from the DIN rail.
Wiring
Please note:
} Information given in the "Technical details [ 22]" must be followed.
} Outputs 13-14, 23-24 are instantaneous safety contacts; outputs 37-38, 47-48 are
delay-on de-energisation safety contacts, semiconductor output Y32 is an auxiliary out-
put (e.g. for display).
} Semiconductor output Y32 should not be used for safety circuits!
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 22]).
} Calculation of the max. cable runs l
max
in the input circuit:
R
lmax
= max. overall cable resistance (see Technical details [ 22])
R
l
/km = cable resistance/km
} 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.
} With U
B
48 – 240 VAC/DC: Connect S21 to the functional earth.
} When connecting magnetically operated, reed proximity switches, ensure that the max.
peak inrush current (on the input circuit) does not overload the proximity switch.
} Ensure the EMC requirements of IEC 60204-1 are met.
} On 24 VDC devices:
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.
