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-circuit bar is removed.
This section uses the 1+1 parallel system as an example to illustrate how to connect cables
to a parallel system. Cable connections for other parallel systems are similar.
