4.4.3 AC side wiring
CAUTION!
Caution, risk of danger
When connecting the AC grid, cut off the circuit breaker at the
AC side to ensure that the AC wire connecting to terminals has
no electricity.
Connect AC grid:
1) Cut off the circuit breaker at AC side, to ensure that the AC wire connecting to
terminals has no electricity. Confirm it with a multimeter.
2)Connect the port A marked at "AC-input" of HPS50 with "L1" of the grid .
3)Connect the port B marked at "AC-input" of HPS50 with "L2" of the grid
4)Connect the port C marked at "AC-input" of HPS50 with "L3" of the grid .
5)Connect the port A marked at "AC-output" of HPS50 with "L1" of the load .
6)Connect the port B marked at "AC-output" of HPS50 with "L2" of the load .
7)Connect the port C marked at "AC-output" of HPS50 with "L3" of the load .
8) Connect "N" of the load and "N" of the grid with the "N" port of HPS50
Ensure that the wiring phase sequence at AC side is in consistent with the phase
sequence at grid side.
9) Please confirm that the wiring is fastened.

4.4.4 Earthing
Inverter must be earthing well for safety; Please make sure of the connection
between PE in power distribution cabinet and PE copper in the inverter good; and
make sure the earthing cable more than 16mm2 and the earthing resistance must
satisfy the demand of IEC standard.
All wiring into the channel at the bottom of the inverter to be all the wiring is
completed, the connection port must be sealed with dust cotton, to prevent dust
from entering the inside of the inverter.
4.5 Communication
The inverter of ATESS PCS series has various communication methods. When the
user needs to monitor the operating status of DC power generation system, we
provide single-machine and multi-machine control programs, and diversified
communication interfaces for customer's selection.
