WARNING
The XSIG interface can either source DC current or accept DC current from and EMS/BMS System. Each configuration
has a different wiring schematic. Wiring the current to the “+” and “Signal” terminals will damage the XSIG interface.
Connecting the XSIG interface to the M4 or S8
• The XSIG Interface connects to the M4 or S8 using an RS485 (phone plug).
• When having to use the RS485 to connect to Extensions, use the extra RS485 (phone plug).
• The control, XSIG Interface and two Extensions can be connected in series using the RS485.
