Example 1:

Supply voltage 24 VDC for electronics, motor holding brake and STO with an external power supply.

External power supply units that provides the 24 VDC supply voltage for connections 24V and STO they must have a "safe isolation" (PELV) according to EN 61800-5-1. The 0 V potential must be connected with PE. The current of the 24V and STO supply must be limited to 6 A each by the user.

 

 

Example 2:

Supply voltage 24 VDC for electronics, motor holding brake and STO with two external power supplies.

External power supply units that provides the 24 VDC supply voltage for connections 24V and STO they must have a "safe isolation" (PELV) according to EN 61800-5-1. The 0 V potential must be connected with PE. The current of the 24V and STO supply must be limited to 6 A each by the user.

Example 4:

Supply voltage 24VDC for electronics and motor holding brake. Bipolar supply voltage with external power supplies.

External power supply units that provides the 24 VDC supply voltage for connections 24V and STO they must have a "safe isolation" (PELV) according to EN 61800-5-1. The 0 V potential must be connected with PE. The current of the 24V and STO supply must be limited to 6 A each by the user.
