2.1.6 Safe Stop Installation - FC 302 only (and FC 301 in Frame Size A1)
To carry out an installation of a Category 0 Stop (EN60204) in
conformance with Safety Cat. 3 (EN 954-1) / PL “d” (ISO
13849-1), follow these instructions:
1. The bridge (jumper) between Terminal 37 and 24 V DC must be
removed. Cutting or breaking the jumper is not sufficient. Re-
move it entirely to avoid short-circuiting. See jumper on illus-
tration.
2. Connect terminal 37 to 24 V DC by a short-circuit protected ca-
ble. The 24 V DC voltage supply must be interruptible by a Cat.
3 (EN 954-1) / PL “d” (ISO 13849-1) circuit interrupt device. If
the interrupt device and the frequency converter are placed in
the same installation panel, you can use a regular cable instead
of a protected one.
3. The Safe Stop function only fulfills Cat. 3 (EN 954-1) / PL “d”
(ISO 13849-1) if particular protection against, or avoidance of,
conductive contamination is provided. Such a protection is ach-
ieved by using FC 302 with protection class IP54 or higher. If
FC 302 with lower protection (or FC 301 A1, which is only de-
livered with an IP21 enclosure) are used, then an operating en-
vironment corresponding to the inside of an IP54 encapsulation
must be ensured. An obvious solution, if there is a risk of con-
ductive contamination in the operating environment, would be
to mount the devices in a cabinet that provides IP54 protection.

The illustration below shows a Stopping Category 0 (EN 60204-1) with Safety Cat. 3 (EN 954-1) / PL “d” (ISO 13849-1). The circuit interrupt is caused
by an opening door contact. The illustration also shows how to connect a non-safety related hardware coast.

954-1) / PL “d” (ISO 13849-1).
