5.2.2 Wiring with a host (master)

{ Danger!

An additional electrical isolation is required if a safe electrical isolation

(reinforced insulation) to EN61800−5−1 is necessary.

For this purpose for instance an interface module for the master computer with an

additional electrical isolation can be used (see respective manufacturer information).

For wiring observe the electrical isolation of the supply voltage. The supply voltage is on the

same potential as the data bus.

The 5−pole plug connector with double screw connection serves to

ƒ connect the bus (¶ 25);

ƒ effect the external voltage supply (¶ 30).
