SX5L COMMUNICATION TERMINAL USER’S MANUAL 1-5
Finger-safe Spring-up Terminal Block Features
Time saving
The innovative terminals on the SX5L series use special, 
spring-loaded screws. This makes installation as easy as push-
ing down and turning with a screwdriver. Installation time is 
cut in half since the screws do not need to be backed out to 
install wiring.
Screw terminals accept bare wire or ring or spade connectors.
Finger-safe
The screws are held captive once installed and are 100% fin-
ger-safe. 
1. Insert the wire connector into the slot in the side of the ter-
minal block.
2. Using a Phillips screwdriver, push down and turn the 
screw.
The wire is now connected, and the screw terminal is finger-
safe.
Detachable
The terminal block can be removed simply by squeezing both 
latches on top of the block inward to unlock the block from 
the socket. To reattach the terminal block, place the block in 
the socket with the latches opened and press the block until it 
bottoms in the socket, then the latches snap outward to lock 
the terminal block.
Wiring can be done with the terminal block removed, so 
installation in narrow areas is quite easy. When replacing the 
SX5L modules, simply remove the terminal blocks and rein-
stall the terminal blocks into the new SX5L module, without 
disconnecting wires.
Insertion pins
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 to prevent 
swapping of upper and lower terminal block.
