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. 161 10-2012, Rev. 1012 Catalog and product specification according Catalog and product data is subject to the Catalog product data, Definitions section, www.te.com to IEC 61810-1 and to be used only together terms of the disclaimer and all chapters of application notes and all specifications are 2012 Tyco Electronics Corporation, with the Definitions section. the Definitions section, available at subject to change. a TE Connectivity Ltd. company.
