5.1 Parallel UPS installation
In the parallel system, the installation of the UPS modular is the same as single UPS.
Please refer to Chapter 3.
Note:
If you configured a '1+1 parallel MBP' modular of this series, it need to be placed to
top layer of the parallel system for rack mounted; or left side for tower installed.
This is for a better cable-connection(as shown below):
