maintenance.

6 kVA UPS and 10 kVA UPS is less than or equal to 50 mA, respectively. When

selecting a residual current circuit breaker, consider the leakage current of the

UPS and its downstream loads.

UPS must be at least 1 m long and the length deviation must be less than

±10%. The four cables must be connected at the remote end.

voltage between the positive and negative battery terminals. Voltage range: 9.6

V x Number of batteries to 14.4 V x Number of batteries. For example, if 20

batteries are installed, the voltage between the positive and negative battery

terminals should range from 192 V (20 x 9.6 V) to 288 V (20 x 14.4 V).

circuit breaker, you are advised to check the leakage current before installing

the UPS. The leakage current of the UPS is less than or equal to 50 mA. Ensure

that the system leakage current does not exceed the rated value of the

upstream residual current circuit breaker after the UPS is installed. Otherwise,

the circuit breaker may trip for protection. Example: The upstream residual

current circuit breaker for the UPS has a rated leakage current of 300 mA. The

system leakage current reaches 250 mA before UPS installation. The leakage

current of the UPS is less than or equal to 50 mA. After the UPS is installed, the

leakage current of the system may be greater than 300 mA (250 mA + 50 mA).

In this case, the upstream circuit breaker will trip for protection.
