Table 3-1 lists only the common tools for installation and cable connection. For more dedicated tools
required, see the document for each component. Prepare tools based on site requirements.
The UPS can generate large leakage currents. A circuit breaker equipped with a residual
current device (RCD) is not recommended.
If multiple UPSs are connected in parallel, input and output power cables for each UPS
should have the same length and specifications.
The TN-C system is supported. If it is used, the input N and PE need to be short-circuited.
