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:
}
" must be followed.
}
Delivery status of units with screw terminals: Link between S11-S12 (dual-channel input
circuit) and link between Y39-Y40 (reset circuit)
}
Outputs 13-14, 23-24, 33-34 are instantaneous safety contacts, outputs 47-48, 57-58 are
delay-on de-energisation safety contacts.
}
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.
}
When connecting magnetically operated, reed proximity switches, ensure that the max.
peak inrush current (on the input circuit) does not overload the proximity switch.
}
Do not switch low currents using contacts that have been used previously with high cur-
rents.
}
The power supply must comply with the regulations for extra low voltages with protective
electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
