Ⅸ. Installation and Regulation install the switch

To protect yourself and the electric device safety, please make sure to do the following things before use the ATS:

read the instruction carefully before installing and using ATS. ATS must be used in the normal working condition.

Check the circuit breaker, to see if their specifications are complied with the work condition before installation.

Before installing, measure the insulating resistance of the circuit breakers with 500V (Katherine Ohm meter)兆欧表 (please note that, when measuring the insulating resistance, please cut the second circuit lead which jointed to the circuit breaker, otherwise the auto transfer controller will be damaged). The resistance should not be less than 10MΩ when the ambient temperature is 20℃±5℃ and relative humidity is 50%~70%. Otherwise the circuit breaker must be dryinged, to make sure the insulating resistance achieve the standard require.

When installing, the safety distance of ATS must be complied with GB14048.1.

When installing, make sure there is no conductive abnormal things on the circuit breaker.

When installing, the conductive bus bar which connected to the ATS’s circuit breaker must be smooth. No attached mechanical strength is allowed to impose on the circuit breaker, avoiding to damage them and their motion character.

After install the switch, choose the leads with suitable section to joint the circuit breaer’s output and input terminals, according to the rated current. The four-pole circuit breaker can joint no lead, only to joint the input terminal. Make sure the null line must be joint correct, otherwise the intellectual controller and motor operating structure will be damaged. As for three-pole circuit breaker, there in a N line must be jointed to the N terminal on the switch body bracket.

Notice: the phase of the two circuit breakers must be coincident, and the switch body must be connected to the earth reliably.

2. manual control and regulation (self-input and self-recover)

When the normal, reserved and controller power supply are connected, the digital tube on the top of controller panel shows two numerical value rows; phase indicative lamps (A,B,C) flash circularly; state indicative lamps (three colors) show the normal power supply green (close), reserved power supply red (open), that means the ATS works under the good condition. If the state indicate lamps are yellow, there is a fault exist in the relative circuit. (three colors of the state indicative lamp respectively means three state: close-green; open-red; fault-yellow) Press the “normal power supply” button, QN circuit breaker close.

Press the “reserved power supply” button, QN circuit breaker open, and QR circuit breaker will close after delay t2.
