Note: 1. Circled numbers are for the user's convenience. When preparing a socket, pay attention

when wiring the terminals to the direction of the polarity guide.

2. The triangular mark (

) on the M7F case indicates the start of the M7F terminal numbers. It

does not line up with the triangular mark (

) on the connector. Incorrect wiring may cause a

short-circuit in the sequence output section, which could damage it.

* This is the location of the triangular mark on the XG4M-2030 Socket that is attached to the

Cable.
