cations
(B) Release holes
(C) Terminal holes
(D) Ground terminal mark
The NX-TB2 and NX-TB1 Terminal Blocks have different terminal current capacities.
The NX-TB2 has 10 A and NX-TB1 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 NX-TB1 or NX-TB2 Terminal Blocks to the Units that the current
capacity specification of the terminals 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 indi-
cate 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 ground terminals. It is only on the NX-TBC2.
