Terminal Block
A terminal block is a group of wire connections
on a drive. This manual expresses specific
terminal blocks and connections as a letter,
usually X, a number, a colon (:), and another
number. The letter and number to the left of the
colon represent the name of the terminal block,
for example, X1. The number to the right of the
colon represents the terminal connection, for
example 4, on the terminal block. In this
manual, a terminal connection numbered 4,
located on a terminal block named X1, is
expressed as X1:4.
