At initial startup, the UPS sets system frequency according to
input line frequency (input frequency auto-sensing is enabled by
default). After initial startup, auto-sensing is disabled until
manually re-enabled by output frequency setting.
At initial startup, inut voltage auto-sensing is disbaled by default.
When manually enabled by output voltage setting, at the next AC
startup the UPS sets output voltage according to input line
voltage. After the subsequent startup, auto-sensing is disabled
until manually re-enabled by output voltage setting.
10. If you installed an optional REPO, test the REPO function:

4.6 Parallel operation

4.6.1 Brief introduction of the redundancy
The parallel structure is 1+1.As long as the UPS is equipped with
parallel cables, up to 2 UPSs can be connected in parallel to
configure a sharing and redundant output power.
4.6.2 Parallel installation
1) Users need to use a specialty 15-pin communication cable for
this series, which should have 15 cores, corresponding stitches
and shield, as the UPS parallel cable. The length of the parallel
cable is appropriate to be less than 3 m.
2) Strictly follow the stand-alone wiring requirement to perform the
input wiring of each UPS.
