Controlling the contac-
tor using AS-Interface
Note
H2 and A1 are internally connected and have the same voltage potential.
Controlling the contactor using
AS-Interface
The AS-Interface + / AS-Inter-
face – terminals are located on a
4 pole plug-in connector that is
separate from the other termi-
nals. Each terminal has two Cage
Clamp connections. The two
AS-Interface + and AS-Interface –
terminals are jumpered as
shown.
• The advantages are:
- The AS-Interface-cable isn’t
interrupted if the terminal con-
nector is removed
- new addressing isn’t neces-
sary
- The contactor remains func-
tional using the local control
inputs on its own 6 pole termi-
nal connector
