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

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 outputs
81-82, 91-92 are auxiliary contacts (e.g. for display).
}
Do notuse 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

} Use copper wiring with a temperature stability of 60/75 °C.
}
To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN 60204-1 must be executed. This includes the separate routing of cables
of the control circuits (input, start and feedback loop) from other cables for energy trans-
mission or the shielding of cables, for example.
}
Adequate protection must be provided on all output contacts with capacitive and inductive
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).
