9.1 Wires Making
1. Wires below are needed before installation.
Conductor Cross-
sectional Area Range
1.Use cables that can withstand
90°C (194°F) or 105°C (221°F).
2.use four single-core outdoor
copper cables (L1, N, L2, PE).
L1, N, L2:10–6 AWG
PE: 6 AWG
1.Use cables that can withstand
90°C (194°F) or 105°C (221°F).
2.Two single-core outdoor copper
cables (L1 and L2)
1.Use cables that can withstand
90°C (194°F) or 105°C (221°F).
2.use four single-core outdoor
copper cables (L1, N, L2, PE).
L1, N, L2:10–6 AWG
PE: 6 AWG
2. Use the diagonal plier to trip 15mm of insulation from one side of the 10AWG wires (7pcs).
Use the diagonal plier to trip one side of GND wire about 7mm (3pcs).
9.2 BACKUP Connection
1.Use the screwdriver to loosen screws in positions L1 and L2 at the contactor’s BACKUP inputs.
2.Insert L1 and L2 of the backup conductors into the BACKUP input terminals of L1 and L2.
3.Tighten to 2.5Nm.
4.Use the screwdriver to secure the backup EGC to the grounding bus bar.
9.4 LOAD Connecrion
After connecting the ATS-US internal wire, close the cover and the GRID and EPS end of the ATS-US are respectively connected with the AC
GRID and EPS output of inverter, EPS load end access load. Run the system, loaded into normal operation.
Trouble shooting
11.
1. In the process of use, if EPS load does not work in on-grid condition, please turn off the inverter and turn off the switch of grid input. Then
open the ATS-US cover, check the GRID and EPS LOAD line is connected properly.
2. If there is no power in load in off-grid condition, please turn off the inverter and open the ATS-US cover, check the control line, the EPS
wiring and the EPS LOAD wiring is properly.
1. Please use the equipment within the scope of specification. Excessive current or voltage may cause device damage.
2. To avoid personal injury due to energy hazard, remove wristwatches and jewelry when repairing. Use tools with insulated handles.
3.The rated power of secondary side L1-N and L2-N could up to 5KVA respectively,and power difference between the tow split phases can not
exceed 3KW.
4.Don't connect N of ATS together with N of grid.
5.Don't connect N of ATS to PE of ATS or PE of grid.
6. Repair is to be performed only by qualified technical personal authorized by manufacturer.
The rated balanced power(L-N)means the Load of L1-N and L2-N is equal.
The rated unbalanced power(L-N)means the load of L1-N and L2-N is different.
