1.1.10. Safe Stop Installation (FC 302 and FC 301 - A1 enclosure only)

To carry out an installation of a Catego-
ry 0 Stop (EN60204) in conformance
with Safety Category 3 (EN954-1), fol-
low these instructions:

The illustration below shows a Stopping Category 0 (EN 60204-1) with safety Category 3 (EN
954-1). The circuit interrupt is caused by an opening door contact. The illustration also shows how
to connect a non-safety related hardware coast.

1.1.11. IT Mains

Par. 14-50
in the 380 - 500 V frequency converters. If this is done it will reduce the RFI performance to A2
level. For the 525 - 690 V frequency converters, par 14-50 has no function. The RFI switch cannot
be opened.
The bridge (jumper) between Termi-
nal 37 and 24 V DC must be re-
moved. Cutting or breaking the
jumper is not sufficient. Remove it
entirely to avoid short-circuiting. See
jumper on illustration.
Connect terminal 37 to 24 V DC by a
short-circuit protected cable. The 24
V DC voltage supply must be inter-
ruptible by an EN954-1 Category 3
circuit interrupt device. If the inter-
rupt device and the frequency con-
verter are placed in the same instal-
lation panel, you can use a regular
cable instead of a protected one.
Unless the FC302 itself has protec-
tion class IP54 and higher, it must be
placed in an IP 54 enclosure. Conse-
quently, FC301 A1 must always be
placed in an IP 54 enclosure.
RFI 1
can be used to disconnect the internal RFI capacitors from the RFI filter to ground
