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 [ 18]" 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 57-58, 67-68 are
delay-on de-energisation safety contacts, output 41-42 is an instantaneous auxiliary con-
tact (e.g. for display).
} Auxiliary contact 41-42 shouldnot be used for safety circuits!
} Do not connect undesignated terminals.
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 18]).

} 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.
} On units with U
B
24 – 240 VAC/DC: Connect operational earth terminal to functional
earth.
} Do not switch low currents using contacts that have been used previously with high cur-
rents.
} On 24 VDC devices:
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.
