Table 3-1 lists only the common tools for installation and cable connection. For more dedicated
tools required, see the corresponding component manuals. Prepare tools based on site
requirements.
3.1.3 Preparing Power Cables
● The UPS can generate large leakage currents. A circuit breaker that provides
leakage current protection is not recommended.
● If multiple UPSs are to be connected in parallel, input and output power cables
for each UPS should have the same length and
specications.
Table 3-2 lists the recommended cross-sectional areas for UPS power cables. Note
that the currents listed are measured at a rated voltage of 380 V (line voltage).
