Use w
ith external device monitoring (EDM): Connect N/C contacts of the controlled actuators
between voltage supply U
V
and S1.
•
Use without external device monitoring (EDM): Connect U
V
and S1 with a wire jumper.
Complementary information
T
o protect and increase the service life of contact outputs, equip all connected loads
with varistors or RC elements. The response times will increase depending on the
suppressor used.
