I. Overview
YDQ4 series ends automatic power switch (hereinafter referred to as switch) for AC 50Hz, rated working voltage 380V, rated current 63A ~ 630A dual power supply system, with automatic or manual mode of operation is completed between the common power supply and standby power switching. The switch is mainly used for important occasions, hospitals, shops, banks, chemical industry, metallurgy, high-rise buildings, military facilities. This product complies with GB/T14048.11-2005 "low-voltage switchgear and control equipment, Automatic Transfer Switching Equipment" standard. This product Electric CB grade level.


Second, the normal working conditions
● The ambient air temperature does not exceed the limit of being forty degrees Celsius, the lower limit of not less than minus five degrees Celsius, and the average value does not exceed twenty-four hours being thirty-five degrees Celsius;
● When no more than fifty percent of atmospheric relative humidity in the ambient air temperature is positive forty degrees Celsius, at lower temperatures can have a higher relative humidity, the wettest month of the monthly average maximum relative humidity of 50 per cent in You can have a higher relative humidity at lower temperatures. Monthly average maximum relative humidity the wettest month of ninety percent, while the average minimum temperature for the month was positive twenty-five degrees Celsius, and taking into account the temperature changes on the product surface condensation;
● installation site altitude of not more than two thousand meters;
● installation category Ⅳ.
● This product should be installed in the absence of severe vibration, shock and corrosion of the place;
● Use category A class.
● When the above conditions are not met, the user and the manufacturer should be resolved through consultation.


Third, the model and the meaning of


Fourth, the basic structure
YDQ4 dual power automatic power switch is mainly executed by the power converter circuit breaker composition, there are three state switching positions for users to choose: the common power supply (N) together, double points, standby power (R) together, switch with volume small, light weight, stable, and easy to use.


Five, installation and use
When wiring, the common power supply should be connected to common power execute N breaker QN, standby power R should be connected to the implementation of the standby power circuit breaker QR. When QN and QR four-wire circuit breakers, wiring according to wiring diagram, where QN and QR 1,3,5 three-phase (A, B, C) into the line side, 2,4,6 for the three-phase outlet end, 7 zero line (N) into the line side, 8 zero line outlet end. If the selection of the circuit breaker for the three-pole circuit breaker, it must be the common power supply (N) of the zero line NN and standby power (R) NR also received zero line on the three-pole dedicated zero line terminal KG. For details, see the wiring diagram. Dual power switch automatic controller working power breaker QN and QR taken into the line terminal A phase and neutral line N, if the choice of circuit breaker for the three-pole circuit breaker, it must be connected to the zero line NN and NR, the three-pole Zero dedicated wiring terminals in the middle of two circuit breakers, the automatic power switch installation, wiring process, do not cut the original breaker into the line connected to the end of the line forget the machine controller, touch off or short circuit.

Using the Operation
regardless of whether the common power supply and standby power supply voltage, can be manually operated. When the hand movements, you should manually - Auto button in the manual position, when the push handle clockwise to the end, the implementation of the standby power circuit breaker QR opening, common power supply execution breaker QN closing; when pushing the handle counterclockwise rotation to the terminal, the standby power supply execution breaker QR closing, the common power supply execution breaker QN opening.
Panel power indicator (red), if the lamp is not lit, indicating that the power supply automatic control box is defective and can not operate the switch. After the restoration of normal, the manual - Auto button in the automatic position state, if the common power supply is normal, the switch will be automatically put into the implementation of the common power supply circuit breaker QN closing state, the panel N Power indicator (yellow) light; if common Power supply is not normal, the switch will automatically switch to standby power supply QR, R standby power indicator (green) lights.
