depending on the control mode selected. The terminal arrangement for these three control modes are
written on the label on

Label on the Front of the Terminal Cover
The terminal numbers are written on the label on the front of the terminal cover. Terminal numbers are
unique three-digit numbers. They are used to locate terminals on the wiring diagram, etc. The highest
digit indicates the arrangement position of the terminal block; the lower two digits indicate the terminal
position within the terminal block (top right terminal is assigned "01" bottom left terminal is assigned
"36"). The terminals that cannot be used are indicated as " ".
