Note: 1. Select an applicable type of short bars by checking applicable socket type, appearance, and dimensions.
2. Use the Short Bars for crossover wiring within one Socket or between Sockets.
3. Use the short bars on the lower section of the socket.
When using the short bars on the upper section of the socket, insert them so that their heads are pointed upwards
(see the figure below).
Otherwise, short bars may interfere with the socket, leading to improper wiring and contact failure.
