Installation
}
The unit 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 (35 mm).
}
When installed vertically: Secure the unit by using a fixing element (e.g. retaining
bracket or end angle).
Wiring
Please note:
}
Information given in the "
Technical details [
16]
" must be followed.
}
Delivery condition: Link between Y1-Y2 (feedback loop)
}
Outputs 13-14, 23-24, 33-34, 43-44, 53-54, 63-64, 73-74 are safety contacts, the out-
puts 81-82, 91-92 are auxiliary contacts (e.g. for display).
}
Do
not
use auxiliary contacts 81-82, 91-92 and semiconductor outputs Y32, Y35 for
safety circuits!
}
Do not connect undesignated terminals.
}
To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [
16]
).

}
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.
}
Do not switch low currents using contacts that have been used previously with high cur-
rents.
}
When connecting magnetically operated, reed proximity switches, ensure that the max.
peak inrush current (on the input circuit) does not overload the proximity switch.
}
With a 24 VDC supply voltage via terminals B1, B2, the power supply must comply with
the regulations for extra low voltages with safe electrical separation (SELV, PELV) in
accordance with VDE 0100, Part 410.
}
Ensure the wiring and EMC requirements of EN 60204-1 are met.
