1 scope of application           The double power series dual power automatic transfer switch is mainly composed of two sets of high breaking capacity of the GTM1 series circuit breaker and the company self-developed automatic switch controller, the rated voltage of 400V and 50Hz, a kind of load rated current 800A and below the high-rise buildings, hospitals, shopping malls, banks, and fire chemical industry, bllurgy, military facilities are not allowed to power, part of the two types of load, power supply double circuit power supply system automatically, so as to ensure the reliability of the important power supply.           This product conbs to GB/T14048.11-2002 IEC60947-6-1 (1998) "standard" automatic transfer switching equipment.           2 normal working conditions           Installation height should not exceed 2000 meters.           Ambient temperature limit is not higher than +40 DEG C, the lower limit of not less than -5 DEG C, 24 hours average value of not more than +35.           And the relative humidity of the atmosphere in the surrounding air temperature of +40 is less than 50%, at low temperature, can have high humidity, should take into account the temperature changes will occur on the surface of the product of frost.           No explosive dangerous medium, and the medium is not enough to corrode and destroy the insulation of the gas and dust.           No significant shaking and shock.           3 installation and wiring b           Wiring common power supply N access to commonly used power execution circuit breaker QN, standby power, access to standby power execution circuit breaker QR. When QN and QR are four line circuit breaker, wiring mode according to the wiring diagram, which QN and QR of 1, 3, three for the three-phase (A.B, C) into the end of the line, 2, 4, 6 for the three-phase outlet, the zero line (N) into the end of the line, the line of zero for the end of the 8 to the end of the.           If the selection of circuit breaker is a circuit breaker, it must be a common power supply (N) of the zero line NN and standby power (R) of the zero line NR also received a special zero line terminal on KG. Specific operation see wiring diagram. Take the line into the circuit breaker QN and QR dual power switch power supply automatic controller end A and zero line N, if the selection of circuit breaker is a circuit breaker, must be connected with the zero line NN and NR, the pole zero terminal special wiring in the middle of the two sets of circuit breakers, the automatic power supply switch is installed. The wiring process, don't cut the line of the original machine controller connected to the circuit breaker terminal the forgotten, broken or short circuit.                       4 use operation           Regardless of normal power supply and reserve power supply has no voltage, can be used in manual operation. Manual operation, manual automatic button should be placed in the manual operation, when pushing the handle clockwise to the terminal, the standby power execution circuit breaker QR gate, commonly used power execution circuit breaker QN switch; when the handle is pushed counterclockwise to the terminal, the standby power supply circuit implementation QR switch, the commonly used power execution circuit breaker QN gate.           Panel, power indicator light (red), if the lamp is not lit, the automatic control box power failure, not the operation switch. To be restored to normal after the manual and automatic button to take automatic b, if the common power supply is normal, the switch will automatically b power execution circuit breaker QN closing state, N panel lights (yellow) light; if the common power supply is not normal, then switching switch will switch to standby QR power supply, standby power, light (green) light.

6 warning           For your safety and equipment, please read the following:           Carefully read the operating rules, and strictly comply with the operating rules, should avoid causing serious losses.           Oath to those who do not regulate the operation of the equipment caused serious losses.           Do not plug the controller plug, otherwise it will lead to electric shock hazard or product damage           Non professional personnel to prohibit the operation or modification, otherwise it will cause an electric shock hazard or product damage           This product users do not need to change, otherwise it will result in product damage           - load capacity can not exceed the rated capacity of the switch, otherwise it will lead to switch tripping or burn           And can not be zero line (n) phase error access circuit breaker, the two b must be consistent with a circuit breaker, the normal power supply (NN) and the standby power supply (RN) with when the zero line to the terminal (KG) pin 1 (n), otherwise it will lead to damage to the switch. The ground should be reliable, to ensure safe use           Can not be directly installed in the outdoor work, or shorten the service life or cause adverse rebs           Can not be directly installed in flammable and explosive, wet, direct sunlight, high temperature, vibration, shock and other places. Otherwise, it will shorten the service life or cause the product combustion explosion.           Can not be directly installed in the conductive dust, bl wire intrusion, otherwise it will result in product damage or mechanical failure.           Should meet the requirements of the sample, otherwise it will shorten the service life. 1 scope of application           The double power series dual power automatic transfer switch is mainly composed of two sets of high breaking capacity of the GTM1 series circuit breaker and the company self-developed automatic switch controller, the rated voltage of 400V and 50Hz, a kind of load rated current 800A and below the high-rise buildings, hospitals, shopping malls, banks, and fire chemical industry, bllurgy, military facilities are not allowed to power, part of the two types of load, power supply double circuit power supply system automatically, so as to ensure the reliability of the important power supply
