Select the appropriate input cables according to Table 3.2 below and Table 3.3 below based on the UPS
rating and mains frequency; however, it is recommended that you size the over current protection and
wiring for the frame rating to easily allow upgrades to the UPS system.

Table 3.3 Input cable selection list—50Hz
To connect the cable:
NOTE: Input and output cables must be run in separate conduit before cable connection. If your input
power grid is L-L line voltage, the input N of the power input and output terminals will connect live wire,
so the output N of the power input and output terminals is also live wire.
1. Remove the knockouts at the junction box, see Figure 3.13 on the next page, and pull the
cables through them, leaving some slack for installation.
