*3: You must prepare the main circuit CT.
The pattern selected here will be used repeatedly in explanations in the subsequent sections.
Set the conversion board according to the corresponding pattern.
(The pattern selected here is described as the “conversion board pattern” in the subsequent
sections.)
How to install the conversion board
Install the conversion board by following its included installation manual.
※
The conversion board is not designed to be removed frequently. Note that installing and
removing it repeatedly may cause contact failures.
Connection diagrams
The wiring method differs according to the conversion board pattern. The connection diagrams
regarding control terminals I1, D1, and V1 are shown below.
※
The connection of other terminals is common to all models and is therefore omitted. See
the connection explained in “5 EXTERNAL CONNECTIONS OF THE UNIT.”
