Relays 1…6, normally-open contacts

IN1…5
--
Common contacts of relays 1…5. May be set to common supply voltage via
terminal 40 by inserting jumpers J1…J5 into their
lower
positions. When, in
contrast, a jumper is in the
upper
position (the so-called “parking position” = default
setting), the corresponding relay receives no supply voltage from terminal 40.

IN6
--
Common contact of relay 6, internally connected to the middle contact of jumpers
J1…J5. May be used to connect common supply voltage.
