Introduction Schneider dual power automatic transfer switching equipment (hereinafter referred to as switch) for AC 50Hz or 60Hz, rated working voltage 400V, rated operating current 63A and below the double-loop power supply system. According to the need for selectivity between two power conversion. Products with a short circuit, overload, under voltage, voltage protection function, but also with fire, double points and closing signal output function. Especially suitable for the need for offices, shopping malls, banks, railway stations, hospitals and high-rise buildings to install fire lighting circuit requirements. 2. Model and meaning undefined 3. ▲ normal operating conditions the ambient air temperature limit does not exceed + 40 ℃, the lower limit is less than -5 ℃, 24h average does not exceed + 35 ℃. ▲ installation site altitude less than 2000m. ▲ atmospheric relative humidity around + 40 ℃ ambient air temperature does not exceed 50%, at lower temperatures can have a higher humidity; ▲ When the wettest month of the monthly average minimum temperature of + 25 ℃, the average The maximum relative humidity of 90%, and taking into account changes in humidity Cream product surface, should take special measures. ▲ Pollution levels for Ⅲ. ▲ run place without a strong vibration and shock, corrosion and damage the insulation of harmful gases, excessive dust, conductive particles and explosive hazardous substances, no strong electromagnetic interference. 4. assembly wiring wiring, commonly used power supply should be connected to the implementation of N breaker QN, standby power should be connected to the standby power to perform R circuit breaker QR and QR when 0N four-pole circuit breakers, wiring according to the wiring diagram in which QN and QR 1,3,5 for the three-phase line-side, three-phase outlet side 2,4,6, 7 zero line 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 zero line also received a zero on three poles dedicated wiring terminals. For details, see wiring diagram. Automatic transfer switch controllers working power from the breaker QR 0N and into the line side and the zero line, if the choice of circuit breaker is three-pole circuit breaker must be connected to the zero line two namely NN and NR, the three a very special connection terminals in two circuit breakers intermediate zero. In the automatic transfer switch installation, wiring process, do not cut into the line connected to the original end of the machine control lines used up, touch off or shorted. 5. Use the operation regardless of whether the common power supply and standby power supply voltage, can be manually operated. In manual operation, the manual should be an automatic button in the manual position, when pushing the handle clockwise to the terminal, perform backup power circuit breaker QN opening, common power supply execution breaker QN closing, when pushing the handle counter-clockwise to the terminal, the standby power circuit breaker QN closing execute, execute common power supply circuit breaker QN opening. Panel power indicator (yellow) indicates the automatic control box power supply, if the lamp is not lit, the power supply automatic control box is defective and can not operate the switch. After the restoration of normal, the manual an automatic button on 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 closing state 0N, N panel power indicator (green); if used Power supply is not normal, it will automatically switch into breaker QN opening, QR closing position state, R panel power indicator (green). 6. Maintenance automatic transfer switch panel 1A has two fuses and a three terminal blocks, fuse as short-circuit protection automatic control box, the terminals compared to the lights to the control box panel provide an active power source voltage is AC 220V Power is 150Ma, where 1 is the common power signal power signal 2 is standby power supply, the specific operation may refer onboard wiring diagram of the control box lights external dotted line.
