Note: this wiring diagram is only fit for 4 pole ATS, when
choose 3 pole ATS, zero line of Main power (NN) must be connected
to the 3 pole zero line terminal.
Use of Operates and supportsWhether main power or backup power
with voltage or not, all can be by manual mode ope
rated.Undermanual,put the auto- manual but ton to manu al position,
pull the handle by clockwise to end,Backuppower implementation
circuit breaker Qr i s OFF, implementation of MAIN power supply
circuit breakerQn ONg; When pull handle counterclockwise to the
end, the implementation of Backup power sourceQr is
ON,implementation of MAIN power supply circuit breaker Qn is
OFF;Set the auto position, if the MAIN power is normally,ATS will
transfer to MAIN power working.The MAINPOWER indiacation will
bright on panel;If the MAIN power is unusually,ATS will t ransfer
to Backup Powerworking.The Backup indication will be bright on the
panel.ATS has 1A of two units fuses and a elec tric connector, fuse
as short-circuit protection in automaticcontroller.Electric
connecto as dry contact in In dication light to panel of controller
box,v oltage of 220VAC, l50mA , the detail please reference to
instruction.
When ATS under automatic control state,the POWER condition was
changed,but the operation mecha-nism no action. Such as MCB can't
closed-transition or open - transition then should be
checked:1.whether the power grid are failured;2.whether the wiring
shedding;3.the fuse itself whether burning. If the front point of
one circuit breaker with ele ctricity, and th e conne- ction are
botht wiring well, fuses are intact, but yet can not
closed-transition or open-transition.You should be asked to
professionals or contact manufactory.
Notice to users in ordersWhen User place the order need to
notice the identifying device model s, spe cifica tions, dis
pensedbreaker models, speci fications, pole number. Such as :
Automatic Transfer Switch device, Self-inputandSelf-recovertype,
rated current of 50 A,4 pole, which is written EATS1-63L/4P
(50A).For users special requirements, please contact with factories
and to explain well in orders indicate.

Working principleWhen common source is n ormal, the functional
key is at position "auto", reserve breaker is open andcommon
breaker is closed to protect common source for connecting with
load,the common power voltageindicator is light.When the common
source failures (the voltage is lower than 60% of rated voltage),
thecommon source will transfer to reserve source automatically, the
reserved source voltage indicator is ON,the reserved source working
indicator is ON. After removing the failure of the common
source,this swi tchwill transfer to the common source automatically
again.
