AC Master Inverter Control Panel (optional)
Optionally an AC Master Inverter Control Panel (article number: 70405080) is connected to the
remote port (RS-232). In case of a system with multiple units: Always connect the control panel to
the Master unit. Before using the control panel, make sure the main switch of the connected unit is
at "REMOTE" position before startup.
Terminal for remote switch and CAN termination
This terminal offers two functions:
Remote switch
Install a switch for remote operation. In case of a system with multiple units: Always connect the
remote switch to the Master unit. Make sure the main switch of the connected unit is at
"REMOTE" position.
Jumper for CAN termination
A CAN bus requires two termination points. One at the start and one at the end of the bus. The
AC Master 2500-3500 is equipped with a jumper that activates or deactivates the CAN
termination resistor (jumper closed = termination active ; jumper open = termination not active).
CAN termination is required for systems with multiple units, see section 10.
