1756-PA72/C Input module

The 100 mm clearances above and below the components must be observed. The mounting position must ensure that cool air flows vertically through the filter. This prevents thermal overloading of the filter. A hazardous voltage will be present at the terminals for up to 30 minutes after the system has been shutdown depending on the DC link capacitance. For this reason, opening the device or removing the cover is permitted only after 30 minutes have elapsed since the device was switched to the voltage–free state. All covers must be reattached before the line voltage is switched on. Danger of death! Touching live terminals, cables or device parts can result in serious injury or death! Note If the system is subject to a high–voltage test using AC voltage, any existing line filter must be disconnected in order to obtain a correct measurement result.

Wideband line filter 

The damping characteristics of wideband line filters not only conform with the requirements of EMC standards for the frequency range of 150 kHz to 30 MHz but also include low frequencies as of 2 kHz. As a result, these line filters have an extended function area, which means that they can, to a certain extent, be used regardless of the machine installation location and any unknown line properties (e.g. line impedance). The Wideband Line Filters should be preferably used. TFor sinusoidal current operation, the total length of the power cables from the line filter should not exceed 350 m and for square–wave current operation, should not exceed 500 m!1) The permissible supply voltage of the system depends on the infeed module used. 2) For ring cable lugs to DIN 46234. 3) The first data applies for pin–type cable lugs, the second data applies for finely–stranded conductors without end sleeves 4) The fuse used must have this rated current. Recommendations for the fuses, refer to Table 7-6.

Line Filter

 The line filters for UI modules attenuate frequencies in the range from 150 kHz up to 30 MHz. In conjunction with the consequential implementation of the system configuration according to the Configuration Manual and the EMC installation guideline for SIMODRIVE, SINUMERIK, SINAMICS S 120, when applying the installation guideline, the limit values at the installation location can be attained according to the EC directive EMC. The precondition is that the user takes into account the specific EMC guidelines at the installation location that may possibly apply and makes a final check. From the line filter, total cable lengths up to 500 m are possible!
