Baumuller b maXX BM3400 Series - Protective Conductor and RCD Compatibility

T 6 Installation
6.7 Protetive ondutor and ompatibility to RCD
Due to the operating principle a leakage current >3,5 mA
AC
or >10 mA
DC
can flow via the protective conduc-
tor. On this account a permanent protective conductor is required.
At the b maXX® BM3400 in add ition to the plugged protective connection, the screw terminal, which is
marked with "P E" must be connected to the PE.
WARNING
The following may occur, if you disregard these safety notes:
• serious personal injury
• death
This device can lead to direct current in the protective conductor. If, in case of a direct or
indirect contact a residual-current-operated protective device (RCD) is used, then a RCD of
type B is permitted on the power supply side only. Otherwise other safety precautions, as e.g.
environmental separation with a double or strengthened insulation or by the separation of the
power supply with a n isolated transformer must be used.
Due to high leakage currents, which arise due to the operating principle of the device can result in an early
enabling of the RCD or generally can avoid an enable.
b maXX® BM3400 devices may only operate in connection to public mains if mains filters are used.
If several b maXX® BM3400 devices are operated in a switching cabinet, devices w ithout internal mains
filter are recommended. In this case a common external mains filter must be used, which has to be selected
according to the sum of the currents of all devices used in the switching cabinet. Usually external mains filters
are filters of higher order and they produce less leakage current than internal mains filters.
