2.1.6 Safe Stop Installation
To carry out an installation of a Category 0 Stop (EN60204) in conform-
ance with Safety Category 3 (EN954-1), follow these instructions:
1. The bridge (jumper) between Terminal 37 and 24 V DC must be re-
moved. 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 a regular cable instead of a protected one.
3. The Safe Stop function only fulfills EN 954-1 Category 3 if it is pro-
tected by a Nema 12 or Nema 4 drive. Open Chassis or Nema 1
drives must be mounted in a Nema 12 or higher cabinet to meet
protection requirements for the Safe Stop functionality.

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.

2.1.7 IT Mains
par. SP-50 RFI Filter can be used to disable the factory installed A1/B1 RFI filter option. If this is done it will reduce the RFI performance to A2 level. For the 525 -
690 V frequency converters, par. SP-50 RFI Filter is not available as there is no A1/B1 Factory Installed RFI Filter option.
