The Auto Transfer Transformer (ATS-US) controls the switch of the contactors to provide power to the critical load stated as EPS Emergency
Power Supply load in both grid-tied and off-grid conditions. There is a contactor in ATS-US to provide user a simple connection. ATS-US is
operating with PCS inverter for the purpose of providing the split phase power when grid accidentally or unexpectedly goes off. This
approach allows the home critical contunously to be supplied.

As shown in chart 2.1, the input side of ATS-US is connected with
EPS output of hybrid inverter and grid, the output side is
connected with critical load stated as EPS load. EPS Load is set
default to connect with Grid power.If Grid is lost, EPS Load will
turn the switch to EPS output of hybrid inverter. And there is a
transformer in ATS-US, it can transform 240V to 120/240V split
phase to provide the power to critical load.

1. In the pro cess of use, if EPS l oad does not work in on-grid cond ition, pleas e turn off the inverter and turn off the switch of grid input. Then
open the ATS-US cov er, check the GRID a nd EPS LOAD line is connected properly.
2. If there is no power in load in off-grid conditio n, 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 equipme nt within the scope of specification. Excess ive current or voltage may caus e device damage.
2. To avoid persona l injury due to energy hazard, remove wristwa tches and jewelry when repair ing. Use tools with insulated handles.
3.The rated power o f secondary side L1-N and L2-N cou ld up to 5KVA respectively,and power difference b etween the t ow split phases can not
exceed 3KW.
4.Don't c onnect N of ATS together wi th N of grid.
5.Don't c onnect N of ATS to PE of ATS or PE of grid.
6. Repair is to be performe d only by qualified technical p ersonal autho rized by manufacturer.
The rated b alanced powe r(L-N)means t he Load of L1-N and L2-N is equal.
The rated u nbalanced po wer(L-N)means the load of L1-N and L2-N is different.
