Replace battery with an Eaton supplied battery ONLY! Ensure the UPS has been powered off and safely
isolated from AC input power prior to replacing the battery. Although the UPS may be disconnected from the
utility power, hazardous voltage still may be present through the battery.
The following instructions are for when the UPS is installed in a Class I, Division 2 Groups A B C D or Class I
Zone 2 II C hazardous location.
Do not connect or disconnect the battery unless the area is known to be free of ignitable concentrations.
The battery in the UPS are rated for a 3–5 year service life. The length of service life varies, depending on the
frequency of usage and ambient temperature. Batteries used beyond expected service life will often have
severely reduced runtimes. Replace batteries at least every 5 years to keep units running at peak efficiency
