The NX-TB£££2 and NX-TB£££1 Terminal Blocks have different terminal current capacities.
The former has 10 A and the latter has 4 A.
To differentiate between the two models of terminal blocks, use the terminal number column indica-
tions. The terminal block with white letters on a dark background is the NX-TB£££2.
You can mount either terminal block to the Units that the current capacity specification of the termi-
nals is 4 A or less.
You can only mount the NX-TB£££2 Terminal Block to the Units that the current capacity specifi-
cation of the terminals is greater than 4 A.
Additional Information
• Each power supply-related Unit is compatible with only one of three types of terminal blocks.
You cannot use a terminal block with a number of terminals that differs from the specifications
for a particular Unit.
• The 8-terminal type does not have terminal holes and release holes for following terminal
numbers.
A2, A4, A6, A8, B2, B4, B6, and B8

Name
Terminal numbers for which A and B indicate the column, and 1 to 8 indicate
the line are displayed.
The terminal number is a combination of column and line, i.e. A1 to A8 and
B1 to B8.
The terminal number indications are the same regardless of the number of
terminals on the terminal block.
Insert a flat-blade screwdriver into these holes to connect and remove the
wires.
The wires are inserted into these holes.
This mark indicates the ground terminals. It is only on the NX-TBC££2.
