5.6.2
Remote access for Eaton technical support
The RJ45 connector ETH-1 provides access for remote data monitoring and Eaton technical support.
Category 5 cable is recommended to use for connecting.
5.6.3
Digital signal inputs and outputs
There are three digital signal inputs assigned to the 24 Vdc power supply at the terminal block
X7, pins 3– 6 (see
Table 9. Communication interface terminals
). Digital inputs can be used to read logic
0 and logic 1 levels from the external device, for example, interface protection relay. One of the inputs
can be configured to cease the active power output of the unit.
There are also three short-circuit proof digital signal outputs available assigned to a single power supply
group (+24 Vdc/0.1 A) at the terminal block X7, pins 7 – 12 (see
Table 9. Communication interface
terminals
). Each output requires two-wire signaling. Outputs can be configured to inform operators about
xStorage Compact ESS conditions.
5.6.4
General alarm relay output
There is a dry-contact relay alarm signal available from the terminal block X7, pins 1 – 2 (see
Table 9.
Communication interface terminals
). The relay can be used to inform operators about the xStorage
Compact ESS conditions, for example through a building management system.
5.6.5
Internal communication connections
Terminal block X8 is dedicated for the energy storage system’s internal CAN-bus and system controller
communication connections. All wiring is completed and should not cause any further actions.
5.6.6
Battery breaker wiring
Terminal block X9 is dedicated for the wiring of the battery breaker interface. Wiring from internal battery
breaker CB1 is completed. When using an external battery rack, signal wiring of battery breakers CB2
and CB3 must be prepared in the installation phase. See
Table 9. Communication interface terminals
for
details.
5.7
CAN cabling of internal battery packs
1.
As there is only one primary battery pack, connect the Com IN and Com OUT of the bottom string
together with a short Ethernet cable (patch cable) to close the CAN bus.
2. Connect the Com IN of each battery pack to the Com OUT of the following pack with a short
Ethernet cable.
