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:
NOTE
Input and output cables must be run in separate conduit before cable connection.
1. Remove the knockouts at the junction box (see
Figure 31
) and pull the cables through them, leaving some slack for
installation�
