Notes:
(1) Mounting screws and the fastening
bracket are included in the package.
(2) Mount the relay with the proper mount-
ing direction -- i.e. with the direction of the
NAIS mark on top of the relay case match-
ing the direction of the NAIS mark on the
terminal block. (The
;
direction of the
terminal block is the upward direction of
the relay.)

Mounting and removal of fastening bracket
1. Mounting
Insert the A part of the fastening bracket
into the mounting groove of the socket,
and then fit the B part into groove, while
pressing with the tip of a minus screwdriv-
er.
2. Removal
Slide the B part of the fastening bracket
from the groove in the socket, while press-
ing with the tip of a minus screwdriver.
While the bracket is in this position, keep
pressing the C part of the bracket to the
relay side with your finger, and lift up to
the left side and remove from the groove,
as in the diagram at right.
