Removing the Detachable Terminal Block
To remove the detachable terminal block from the SX5L module, squeeze both latches on top of the terminal block inward
to unlock the terminal block from the socket.
Installing the Detachable Terminal Block
Place the terminal block in the socket with the latches opened and press the terminal block until it bottoms in the socket.
Insertion Pin Positions
Insertion pins are positioned on the base of the terminal block and inside the socket to prevent insertion of invalid terminal
blocks into the socket. The pins are keyed to make sure of correct matching of terminal block and socket, and prevent
swapping of upper and lower terminal blocks.
When the terminal block does not fit into the socket properly, check to see if the pin positions on the terminal block agree
with the pin-slot arrangement in the socket. If the pins and the pin slots are in matching positions, check for any chips and
obstacles in the socket.
When purchasing terminal blocks separately, set the insertion pins as shown below.
