Eaton T2235 Series eATS ePDUs P-164000014—Rev 1 www.eaton.com/ePDU 1Chapter 1 IntroductionEaton ® T2235 Series Automatic Transfer Switches (eATS) are Enclosure Power Distribution Units (ePDU ®) thatprovide distribution of primary power to controlled devices. They are specially designed for switching non-phasesynchronized AC power sources. The intelligent circuitry in a T2235 Series eATS ePDU monitors both primaryand secondary power inputs.If there is a problem with the primary power source, the eATS ePDU automatically transfers to the secondarypower source. As soon as problems with the primary source are resolved, the eATS ePDU switches power backfrom the secondary to the primary source.The T2235 Series eATS ePDU systems are all designed to operate at an input voltage range of 100–240V (12A,16A, or 24A). All T2235 Series eATS ePDUs are single-phase models that operate at a frequency of50/60 Hz.Front PanelThe front panel provides LED indicators that provide operation status, such as power availability. The LEDindicators also indicate whether the primary or secondary power source is in use.Table 1 illustrates the front panel of a representative T2235 Series eATS ePDU model.Figure 1. Front Panel (T2235-AB-NNBC20 model shown)Rear PanelPower input is provided through either an attached cable or a detached cable connected to a power inlet on therear panel. Power output is through a variety of outlet configurations located on the rear panel.Several types of input plugs are available on the T2235 Series eATS ePDUs, such as L5-20P. L5-30P, L6-20P,L6-30P, L5-15P, L5-20P, 5-15P, 5-20P, and IEC60320 C20.Various output receptacles are available on the T2235 Series eATS ePDUs, such as NEMA 5-15R, NEMA 5-20R,NEMA L5-20R, NEMA L5-30R, NEMA L6-20R, NEMA L6-30R, IEC60309 C13, and IEC60309 C19.Figure 2 illustrates the rear panel of a representative T2235 Series eATS ePDU.Figure 2.
