Danger!
Additional electrical isolation must be installed if
ƒ
an 820X and 821X controller is connected to the host and
ƒ
reliable electrical isolation (reinforced insulation) in
accordance with EN 61800-5-1 is needed.
For this, you can use an interface module for the host with an additional
electrical isolation (see the corresponding manufacturer’s information).
For wiring, the electrical isolation of the supply voltage must be taken into
account. The supply voltage is assigned to the same potential as the data
bus.
