2.1.6 Safe Stop
The AF-650 GP can perform the safety function Safe Torque Off (As defined by draft CD IEC 61800-5-2) or Stop Category 0 (as defined in EN 60204-1).
It is designed and approved suitable for the requirements of Safety Category 3 in EN 954-1. This functionality is called Safe Stop. Prior to integration and use of
Safe Stop in an installation, a thorough risk analysis on the installation must be carried out in order to determine whether the Safe Stop functionality and safety
category are appropriate and sufficient. In order to install and use the Safe Stop function in accordance with the requirements of Safety Category 3 in EN 954-1,
the related information and instructions of the AF-650 GP Design Guide must be followed! The information and instructions of the Operating Instructions are not
sufficient for a correct and safe use of the Safe Stop functionality!
2.1.7 Safe Stop Installation
To carry out an installation of a Category 0 Stop (EN60204) in conformity with Safety Category 3 (EN954-1), 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. 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 frequency converter are placed in the same installation panel, you can use an unscreened cable instead
of a screened one.

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.
