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 [ 13]" must be followed.
} Outputs 13-14, 23-24, 33-34 are safety contacts; output 41-42 is an auxiliary contact (e.g.
for display).
} Auxiliary contact 41-42 shouldnot be used for safety circuits!
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 13]).
} Calculation of the max. cable length l
max
in the input circuit:
R
lmax
= max. overall cable resistance (see Technical details [ 13])
R
l
/km = cable resistance/km
} Use copper wiring with a temperature stability of 60/75 °C.
} To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN60204-1 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.
} 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.
