Terminals location and conceptual connection diagram
Connect the contact input lines or pulse signal lines to the Di1, Di2, Di3, Di4, and COM terminals of the orange connector located on the
rear face. Each terminal has a different function.
[Di1] Emergency stop input
[Di2] [Di3] [Di4] Pulse input, contact signal input
[COM] Common
This function assignment, however, may be changed at a later time. For how to change the function assignment, refer to the commissioning
manual.

connection>
NOTE
The COM terminals are all connected internally. So, you
can use either of them.
However, you can connect up to two wires simultaneously
to each COM terminal.

CAUTION
• The contact connected to the contact input terminal must be capable of handling 10 mA at
16 VDC.
• If an instantaneous contact is used for triggering an emergency stop, use one that has an
energization time of 200 ms or more.
• Do not clamp the cables with high-current lines such as a power cable.
NOTE
When emergency stop input signal is enabled, you cannot restart all the air conditioners unless you
disable it.
