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.
