General
BQ series dual power automatic transfer switch is suitable for power supply system with AC 50/60Hz, rated working voltage AC400V, rated working current 800A and below.
It is possible to select and switch between two power sources according to requirements, ensuring uninterrupted operation of key power sources. When one power supply has overvoltage, undervoltage or phase loss, it will automatically switch to another power supply or start the generator.
Built-in RS485 communication interface, communication protocol MODBUS-RTU, realize real-time data upload, remote data configuration and status monitoring, as well as remote control, telemetry, remote control and remote adjustment functions.
Mainly used in hospitals, shopping malls, banks, hotels, high-rise buildings, fire protection and other places that do not allow long-term power outages with uninterrupted power supply required.

Switching device installation: After fixing the switching device, according to the rated current to choose the appropriate wires to wire.
Note: The phase sequence of main power and emergency power must be consistent.
Split type controller installation:
Use 2 strutting pieces to fix the split type controller on the panel.
Please check if the controller has been plugged into switching device and fastening screw. Please check whether each electric contact part is reliable and the fuse if good.
If user wants to withstand voltage test, please remove the controller first. Otherwise the controller will be broken down. For the 3 pole switch, user needs to connect main power neutral line to terminal N1 port.
Connect emergency power neutral line to terminal N2 port. Neutral line must be reliable and don't connect wrong so that ATS could proper work.
For the 4 pole switch, main and emergency power neutral line must be connected to the corresponding circuit breaker N pole. In addition,switching device should ground connection at the grounding mark.
User could connect indicator light to the terminal for observation. Refer to the wiring diagram below.
Note:
This diagram applies to three-phase four-wire. When using three-phase three-wire system, the neutral line of main power connects to terminal N1 port,neutral line of emergency power connects to terminal N2 port.
HD main power indication AC220V(User-provided).
TD main power indication AC220V(User-provided).
