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 adjustable frequency drive are placed in the same installation panel, you can use a non-
shielded cable instead of a shielded one.

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