6.2 Chassis Grounding
In this section, “Chassis Ground” is referred to as “ground” or “grounding” unless otherwise mentioned.
The AC and DC grounding are intended to provide a low impedance signal path at all frequencies.
DC Ground Wiring Installation: The PCS cabinet is shipped with ungrounded DC power terminals within the inverter. However, the
default setting for DC grounding is set for DC negative to ground. This is to indicate that the DC negative terminal of the inverter is
grounded within the PCS system. The DC negative ground is completed once terminated in the master battery cabinet.
AC Ground Wiring Installation: The AC power grounding is achieved through the PE terminals of the AC grid connectors on the AC
Filter Board, as shown in section 6.1.
Note: The field ground wire rating applies to the AC circuit only
. The DC source loop is internal to the battery cabinet,
and is rated accordingly.
Lightning Grounding: The inverter has built-in lightning protection. In order for the lightning protection to be effective, the
grounding for lightning currents must be provided via low impedance path from AC Filter Board to System Ground and further to
the building Ground/Earthing point.
6.3 Communication Wiring to the Energy Management System – RJ45 Pin-out
The EMS panel supplied with the Evolve LFP includes a 10 ft factory prepared cable. Refer to the Evolve Hub installation manual
supplied with your equipment for connection instructions to the EMS.
Note: The Evolve LFP communicates with the energy management system using the Modbus protocol over an RS-485
network. Shielded twisted pair cable is required.
Should the installation require further separation between the EMS
panel and the Evolve PCS cabinet (ACB05U-LP), a cable can be prepared using CAT 5 shielded wire, with an RJ-45
connector terminated at the PCS end only. Connect the shield to the EMS end only.
Terminate the cable as shown:
