Only qualified service personnel (such as a licensed electrician) should perform the UPS
installation and initial startup. Risk of electrical shock.
To hardwire the UPS:
1. Verify that the electrical connections to the installation site have
been properly installed.
2. A wall-mounted, user‐supplied, readily‐accessible disconnection
device must be incorporated in the input wiring.
Compare the circuit breaker ratings to the specifications in Table 3
on page 25.
NOTE To accommodate the feature of easy system expandability, it is recommended that
initial installation of the Eaton 9355-F47 Unirom UPS contain wiring to support the maximum
capacity of the UPS.
3. Notify others working in the immediate area that the UPS is under
maintenance control.
4. Switch off utility power to the distribution point where the UPS will
be connected. Be absolutely sure there is no power.
