Installing AC Input and Output Power Cables
1. Connect UPS AC input and output terminals L, N correctly. For a UPS with long backup time,
connect the battery terminals correctly.
2. Before connecting cables, ensure that the input circuit breaker and output circuit breaker
are OFF. For a UPS with long backup time, ensure that the battery circuit breakers are OFF.
Perform all tasks with the power off.
Refer to the UPS installation method on page 3 to install each UPS in the parallel system.
Installation Parallel System
1. The professional version supports parallel connection, and the standard version does not.

For a single UPS, install a short-circuit bar between JP1 and JP2. For a parallel system,
do not install it. When transferring from single mode to parallel mode, confirm that the short-
