To tighten the terminal block, a flathead screwdriver having a tipped size of 0.4  2.5mm is required.
Before removing the transmission cable terminal block, check that the terminal block mounting screws on both
ends are completely loosened (removed from the socket).
Pulling the terminal block with excessive force while the terminal block mounting screws on both ends are still
tightened may damage the devices.
Before connecting the terminal block, check that there are no short-circuits due to the disconnected or frayed
wires and tighten the terminal block mounting screws at both ends securely. (Tightening torque: 0.2 to 0.3Nm)
(3) Cable processing
Bare cables can be connected to the transmission cable terminal block; however, for safety reasons, it is
recommended to connect cables using bar solderless terminals.
Use UL-listed solderless terminals and, for processing, use a tool recommended by their manufacturer.
