Li-ion Batteries)
•
The cabinet must be powered on within seven days after installation.
•
During the power-on, before and after turning on each of the MCBs for the first time, you need to use a
multimeter to check the input and output voltages and ensure that the voltages are normal (AC ranges: 200
VAC to 240 VAC; DC range: -42 VDC to -58 VDC).
•
After installing the cabinet and powering on the device, ensure that the battery switch is in the ON state. If the
device needs to be powered off, you must first turn off the battery switch and then turn off the AC switch.
Use the multimeter to test the input voltage for the
device.
Turn on the switches of the AC PDU.
Check whether the status of the power supply, fan,
