2.5.1 Transformer-Free UPS Cable Connection
A junction box is factory-installed on each model of the SolaHD S5KC to ease cable connection.
Select the appropriate input cables according to Table 3 and Table 4 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.
To connect the cable:
1. Remove the knockouts at the junction box (see Figure 31) and pull the cables through them,
leaving some slack for installation.
