Applicable Terminal Blocks for Each Unit Model
The following indicates the terminal blocks that are applicable to each Unit.
Precautions for Correct Use
You can mount either NX-TB
1 or NX-TB
2 Terminal Blocks to the Units that the cur-
rent capacity specification of the terminals is 4 A or less.
However, even if you mount the NX-TB
2 Terminal Block, the current specification does
not change because the current capacity specification of the terminals on the Units is 4 A or
less.
Refer to
A-4 List of Screwless Clamping Terminal Block Models
on page A-54 for information
on the models of terminal blocks.
