} When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket or end angle).
} Push the device upwards or downwards before lifting it from the DIN rail.
Wiring
Please note: } Information given in the “Technical details [ 22]” 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 and semiconductor output Y32 should not be used for safety cir-
cuits! } To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 22]). } Calculation of the max. cable length lmax in the input circuit:
Rlmax I= max Rl / km
Rlmax = max. overall cable resistance (see Technical details [ 22]) Rl / km = cable resistance/km } Use copper wiring with a temperature stability of 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 transmission or the shielding of cables, for example. } Adequate protection must be provided on all output contacts with capacitive and inductive loads. } With UB 48 ­ 240 VAC/DC: Connect S21 to the functional earth. } When connecting magnetically operated, reed proximity switches, ensure that the max. peak inrush current (on the input circuit) does not overload the proximity switch. } 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.
NOTICE If you connect contact expansion modules to a base unit with a universal power supply, you will need to limit the conventional thermal current at the contact expansion modules’ safety contacts to 70 % of the stated current (see technical details for contact expansion module).

Operation
When the relay outputs are switched on, the mechanical contact on the relay cannot be tested automatically. Depending on the operational environment, measures to detect the non-opening of switching elements may be required under some circumstances. When the product is used in accordance with the European Machinery Directive, a check must be carried out to ensure that the safety contacts on the relay outputs open correctly. Open the safety contacts (switch off output) and start the device again, so that the internal diagnostics can check that the safety contacts open correctly } for SIL CL 3/PL e at least 1x per month } for SIL CL 2/PL d at least 1x per year
NOTICE The safety function should be checked after initial commissioning and each time the plant/machine is changed. The safety functions may only be checked by qualified personnel.
The unit is ready for operation when the Power LED is permanently lit. LEDs indicate the status and errors during operation:

Supplementary data
CAUTION! It is essential to consider the relay’s service life graphs. The relay outputs’ safety-related characteristic data is only valid if the values in the service life graphs are met.
The PFH value depends on the switch frequency and the load of the relay output. If the service life graphs are not accessible, the stated PFH value can be used irrespective of the switch frequency and the load, as the PFH value already considers the relay’s B10d value as well as the failure rates of the other components.
Service life graph The service life graphs indicate the number of cycles from which failures due to wear must be expected. The wear is mainly caused by the electrical load; the mechanical load is negligible. Unit types with UB 24 VDC } UB: 24 VDC; Order no. 750104, 751104, 751184

To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With DC contactors, use flywheel diodes for spark suppression.

Example } Inductive load: 0.2 A } Utilisation category: AC15 } Contact service life: 1 000 000 cycles Provided the application to be implemented requires fewer than 1 000 000 cycles, the PFH value (see Technical details [ 22]) can be used in the calculation. To increase the service life, sufficient spark suppression must be provided on all relay contacts. With capacitive loads, any power surges that occur must be noted. With DC contactors, use flywheel diodes for spark suppression.
