PC board mounting method PC board pattern The terminal configuration is symmetrical on the left and right, so an arrow mark is stamped on the socket to prevent mis- insertion. We recommend printing the same arrow mark on the component mounting side (side opposite from pat- tern) of the PC board. In this case, the ter- minal configuration becomes the terminal nos. noted near the drilling holes. 2.

The range for chassis thickness is 0.6 to 2.2 mm .024 to .087 inch . 3. Relay mounting and removal (1) Align the directions of the relay and socket. Claw for chassis fastening Chassis t = 0.6 to 2.2 .024 to .087 Press A side Relay (2) Insert the relay all the way in, so it is secure- ly in place. (3) Press the part indicated by A in the B direc- tion, and fasten by placing the hook on the re- lay. (4). When removing the relay, completely re- lease the hooks on both sides and pull the relay out.
