Safe Stop Installation (FC 302 only)

"
To carry out an installation of a category 0 stop
(EN60204) in conformance with safety category
3 (EN954-1), follow these instructions:
The bridge (jumper) between terminal 37 and
1.
24 V DC of the FC 302 must be removed.
Cutting or breaking the jumper is not sufficient.
Remove it entirely to avoid short-circuiting.
See jumper on illustration.
2. Connect terminal 37 to 24 V DC by a
short circuit-protected cable. The 24 V DC
voltage supply must be interruptible by an
EN954-1 category 3 circuit interrupt device.
If the interrupt device and the adjustable
frequency drive are placed in the same
installation panel, you can use a regular
cable instead of a protected one.
The illustration below shows a stopping category 0 (EN 60204-1) with safety cat. 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.

60204-1) with safety cat. 3 (EN 954-1).
