1.General
The dual power automatic switch is a newly developed miniature householdpower switch, which is mainly used to test whether the main power supply or standbypower supply is normal. When the normal power supply is abnormal, the standbypower supply starts to work immediately, which ensures the continuity, reliability andsafety of power supply. This product is specially designed for household rail installationand is specially used for Pz30 distribution box.The dual power automatic switch is suitable for emergency power supply systemswith 50 or 60Hz and rated 400V AC. ATS has the characteristics of solid structurereliable conversion, convenient installation and maintenance and long service life.It is widely used in various occasions where power failure cannot be sustained, andcan be operated by electricity or manually. ATS is composed of TSE and controller.According to GB/T14048.11, Part 6-1: multifunctional equipment and switchgearis formulated. lt can be seen that ATS is the most qualified low-voltage switchgearand control device.
2.Normal operation time and installation conditions
2.1 Ambient air temperatureThe maximum temperature shall not exceed 40℃, the minimum temperatureshall not be lower than -5℃, and the average temperature within 24 hours shallnot be higher than 35℃2.2 Altitude
The altitude of the installation site should not be higher than 2000m.2.3 Atmospheric conditions
When the maximum temperature reaches 40℃, the relative humidity of theinstallation site should not exceed 50%; when the temperature is the minimum tem-perature -5℃, the relative humidity is higher, for example, the temperature is 25℃and the relative humidity is 90%. Due to the temperature change, special measuresshould be taken to deal with the occasional condensation on the surface of the product.2.4 Pollution grade
The pollution grade of ATS conforms to grade 3 specified in GB/T14048.11.2.5 Installation category
The installation type of ATS conforms to the category specified in GB/T14048.11.2.6 Installation conditions
ATS can be installed vertically in control cabinet or distribution cabinet. Makesure the installation distance meets the requirements in Figure 1.

7.Installation and wiring
7.1 Ensure that professionals read this manual before installation and wiring.7.2 Please check the integrity of ATS before installation, then open and close ATSwith the operating handle, check the flexibility of transmission device and detectthe load generation and disconnection conditions of common and standby powersupplies at each stage.7.3 See the figure for the correct installation steps. The trademark is in front of theproduct. lf the installation cannot be carried out according to the correct proceduresdue to wiring and other reasons, please contact us. The safe distances S1.S2should not be lower than the labels in Fig. 8. (See figure below for details)7.4 Detection control voltage: 50Hz, AC220V. The coil in the control circuit cannotbe too long. The cross-sectional area of copper wire should not be greater than2.0mm .
7.5 According to the installation requirements of power distribution system, pleaseprovide appropriate circuit breakers to ensure the safety of staff and equipment.
8.Maintenance,inspection and storage
8.1 Maintenance and inspection shall be operated by professionals and all powersupplies shall be cut off in advance.
8.2 In order to ensure the good performance of ATS, the first maintenance andinspection shall be carried out within 6 months after use, and shall be maintainedand inspected at least once a year. In harsh installation conditions, the frequencyof maintenance and inspection should be increased.
8.3 Maintenance and Inspection ltems
Please remove dust and dirt in case of failure,
Please check whether the contact parts of the electrical contacts are deformedand damaged, and remove bumt metal particles attached to and around the surface.c. Rust, acidification and dust on the contact surface may lead to poor contact. Pleaseoperate manually many times and measure the contact resistance if necessaryd. Due to long-term moisture and suspension, please dry ATS before use. Afterremoving dust and dirt, use a 500V megohmmeter to measure the insulationresistance between normal supply, altemnating power supply, load side bar, includinglive parts and metal plate. And the insulation resistance should not be less than1 OM.
8.4 ATS shall be stored in an environment equivalent to the normal working environ-ment, with dust-proof, moisture-proof and collision-proof measures.
9.Matters needing attention
9.1 Manual/automatic operation
ATS can guarantee the performance of power generation and power failure duringcircuit operation, but for manual operation, ATS cannot guarantee the above performance due to the difference of power generation and power failure speed or operator.During manual power generation and power failure, excessive silver alloy loss mayoccur. Therefore, when all power supplies are cut off to check and maintain theoperating system and contacts, it is only necessary to pull the selector switch to themanual position. Under normal circumstances, please pull the selector switch to theautomatic position. When operating manually, pull the selector switch to the manualposition. After the manual operation is completed, pull the selector switch from themanual position to the automatic position.
9.2 Control circuitATS instantly becomes active. After the conversion is completed, the coil in thecontrol circuit will be disconnected by the interal converter. Under the rated voltageof 80%-110%, the coil can operate normally. Low voltage will cause coil heating andeven spontaneous combustion.
