Verifying the Installation
1. Check that there is no foreign matter in the cabinets.
2. (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.
Sealing putty must be used as a whole and
the gap can be sealed only from the top.
3. After verifying the installation, reinstall all the covers.
4. Do not remove the dustproof cover before power-on to prevent dust from entering the UPS.
