3.3.2 Rack Installation
1. Various installation configurations are available: single UPS, single UPS with
single or multiple-battery. Their installation methods are all the same.
2. Because battery cabinets are too heavy, they must be installed first, and two or
more installation personnel are required to install them at the same time. Please install
them from bottom to top.
Rack installation: fix the UPS and battery cabinet onto the rack through brackets.
Installation method:
1. Fix the brackets onto the UPS with the screws, as shown in Fig.3-4.
