Verifying the Installation
1. Check that there is no foreign matter at the top 
and bottom of the cabinets, copper bars, 
switches, and the rear of units.
2. After verifying the installation, reinstall all 
the covers. 
3. (Remove the paper protective film from the 
sealing putty.) After routing cables and 
verifying cable connections, seal the gap 
between cables and the cabinet using 
sealing putty. 
4. Do not remove the dustproof cover before power-on to prevent dust inside the UPS.
