Start the forced start device, make the equipment into the inverter emergency operation mode, and until the discharge is terminated, the over-discharge protection of the equipment should not be activated.
In some cases, the inverter emergency power supply is used. When the inverter is in the emergency operation mode, even if the battery as the intermediate DC power source is discharged to the cut-off voltage, it still needs to be kept running for a certain period of time to ensure the maintenance in a specific emergency. A certain amount of electrical energy, to maintain emergency power supply requirements for electrical equipment such as lighting, the inverter emergency power supply selected at this time should have a mandatory start function. For devices that have a forced start function, a forced start test is required.
During the test, the mandatory emergency starting device is operated by a professional. After the forced start, the inverter emergency power supply is transferred to the inverter emergency operation mode until the discharge is terminated. When the cutoff voltage is reached, the overdischarge protection does not work and the equipment should work normally. This test can be performed in conjunction with emergency power supply time or battery pack over-discharge protection test.
While conducting a general inspection, check that the EPS power supply is installed with the appropriate special equipment as required.
In equipment used in areas such as frequent lightning, when required by the user, the equipment should be equipped with special equipment to prevent surge and lightning shock. When conducting a general inspection, it should be checked whether the device is properly installed in accordance with the specifications.
