Connect the "BUS IN" connector to the upstream device (PLC etc.) and connect the "BUS OUT" connector
to the downstream device.
The M12 connector cable has two types, SPEEDCON compatible and non-compatible. If both plug
and socket sides have connectors for SPEEDCON, the cable can be inserted and connected by
turning it a 1/2 of a rotation, leading to reduction in work hour.
A non-compatible connector can be connected to a compatible connector as well as an M12.
Note
•Be sure to fit a seal cap on any unused connectors.
Proper use of the seal cap enables the enclosure to achieve IP67 specification.
: Refer to page
30
for the seal cap.
