3.2 Installation Procedure
UPS installation includes mechanical installation and cable connection. Installation modes
include tower installation and rack installation. You can select an installation mode based on
the site requirements.
3.3 Installing a Backfeed Protection Device
The UPS has no built-in backfeed protection device. You can install a backfeed protection
device on the input front side.
If you do no install a backfeed protection device on the input front side, attach a warning label
to the main power isolation device. The label reads like this: "This circuit supplies power to
the UPS. Before cable connection, disconnect the UPS, and check the voltage across wiring
terminals."
When battery mode is unavailable or the mains fails, the UPS internal voltages or energy may
flow back directly, or through a leakage path, to an input terminal. To minimize the risk of
electric shocks, install a backfeed protection device on the input side.
