The Eaton xStorage 400 is designed to operate for extended periods of time without maintenance. All xStorage

performed on an as-needed basis.

Due to the presence of batteries, the xStorage 400 interior is unsafe until the DC power source is
disconnected, and the electrolytic capacitors are discharged. After disconnecting the utility power and the DC
power, authorized service personnel should wait at least five minutes for capacitor to bleed off before
attempting any internal access.
Servicing and maintenance should be performed by qualified service personnel only.
Because each battery string is an energy source, opening the battery circuit breaker does not de-energize the
voltage within the battery string.
DO NOT ATTEMPT TO ACCESS ANY INTERNAL AREA OF THE BATTERY
STRING YOURSELF. VOLTAGES ARE ALWAYS PRESENT IN THE BATTERY STRING. If you suspect that a
battery string needs service, contact an Eaton service representative.
