Modbus/BMS port and DIP switch
The Modbus/BMS port supports Modbus connectivity, or BMS communication for
Lithium Ion battery monitoring.
The port defaults to Modbus the function, which can provide communication with a
maximum of 5 UPS. For daisy chain connection, a splitter terminal block is required
(please contact your service representative for this splitter). There are two switches
on the DIP switch bank: SW-2 and SW-1. Both are default to the Off position. On the
DIP switch bank, SW-2 is the enable terminal resistance switch. Turn this switch to
the On position when this is used as a terminal device.
For Lithium Ion battery BMS monitoring, switch the SW-1 to the On position.
Intelligent Communication Card Slot
This slot enables installation of various compatible MS (mini-slot) type
communication cards. These are: NETWORK-M2, INDGW-M2, and RELAY-MS
cards. Cards are hot-pluggable and hot-swappable. Contact your Eaton
