NB!
Unsuccessful AMA is often caused by incorrectly registered motor name plate data or too big difference between the motor power size
and the VLT AQUA Drive power size.

5.7.1 Safe Stop Installation
To carry out an installation of a Category 0 Stop (EN60204) in
conformance with Safety Category 3 (EN954-1), follow these
instructions:
1.
The bridge (jumper) between Terminal 37 and 24 V DC of FC
202 must be removed. Cutting or breaking the jumper is not
sufficient. Remove it entirely to avoid short-circuiting. See jump-
er on illustration.
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 an
EN954-1 Category 3 circuit interrupt device. If the interrupt de-
vice and the frequency converter are placed in the same instal-
lation panel, you can use a regular cable instead of a protected
one.
Illustration 5.37: Bridge jumper between terminal 37 and 24
VDC.
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.
