Grounding provisions
Pre-installed on sockets
Not for use at 5A AC and above.
Grounding Strip: Mounting stud of relay contacts grounding strip. Grounding
strip is grounded with screw or rivet through round hole in socket.
Grounding Terminal (PC sockets only): Mounting stud of relay contacts ground
terminal through square hole in socket.
Caution:
Strip Terminal
Printed circuit sockets are manufactured with floating (loose) terminals. This
permits them to align with holes in the circuit board and with the relay termi-
nals. During the mounting and soldering of the socket, vertical float should be
eliminated and the terminals seated on the board. (This may be accomplished
by inserting a dummy relay in the socket.) Failure to eliminate float may cause
fracture of the solder joint or separation of the copper conductor from the
printed circuit board when a relay is inserted in the socket after soldering.
