3.7.3 Connecting Cables on a Transformer-free UPS with Dual Inverter Frames
A junction box is factory-installed on all models of the Liebert APS to ease cable connection.
Select the appropriate input cables according to Table 3.10 below andTable 3.11 on the next page based
on the UPS rating and mains frequency. We recommend sizing the overcurrent protection and wiring for
the frame rating to easily upgrade the UPS system.
