Chapter 1 Introduction Eaton® T2235 Series Automatic Transfer Switches (eATS) are Enclosure Power Distribution Units (ePDU®) that provide distribution of primary power to controlled devices. They are specially designed for switching non-phase synchronized AC power sources. The intelligent circuitry in a T2235 Series eATS ePDU monitors both primary and secondary power inputs. If there is a problem with the primary power source, the eATS ePDU automatically transfers to the secondary power source.
Introduction Dimensions The T2235 Series eATS ePDUs are designed to mount in a standard 19-inch equipment rack with the following typical chassis dimensions: l 482.6 mm (19.0”) wide l 44.5 mm (1.75”) high l 177.8–24.3 mm (7.0–9.5”) deep NOTE There is currently one height exception. One custom-built T2235 Series eATS ePDU model with two rows of outlets (16 receptacles) is available. This model is 86.4 mm (3.4”) high.
Introduction Benefits The benefits of the T2235 Series eATS ePDUs are as follows: l l l l Provides dual power inputs and automatically selects the input source best suited to power-critical equipment. Meets Agency relay spacing requirements for out-of-phase switching up to 30A, while still performing fast enough to minimize transfer time. Provides power redundancy to equipment with one or two power supplies.

Chapter 3 Installation The Eaton T2235 Series Automatic Transfer Switch (eATS) Enclosure Power Distribution Unit (ePDU) models have a 19” chassis composed of 16 gauge (Ga.), electrolytic galvanized (EG) or cold roll (CR) steel plate. The T2235 Series eATS ePDU can be mounted on a rack or in a cabinet that accepts standard 19” width spacing. The ePDUs are installed in a 1U orientation. Installation of a T2235 Series eATS ePDU is to be performed by qualified, trained technicians.
Installation KIT-CABLRES-03 Universal Cable Restraint System The following parts for installing the optional cable restraint tray are located in the KIT-CABLRES-03 shipping carton: l (1) Cable management tray (001-2211-2) l (2) Mounting brackets (001-2233-2) l (11) 6-32 X 1/4” black screws (035-1606) l (12) Tie-wraps, 8” (010-0008) Before You Install Consider where you will locate the T2235 Series eATS ePDU model. These models are typically mounted at the bottom or rear of the equipment cabinet.
Installation Figure 4 shows an example cable restraint tray installed on an eATS ePDU in a rack. J3 J2 J1 Y AR ND CO SE Y AR IM PR Figure 4. Cable Restraint Tray Installation Installing the T2235 Series eATS ePDU CAUTION For PLUGGABLE EQUIPMENT, the power outlet you intend to use must be near the equipment and readily accessible. CAUTION Confirm that the equipment connected to the ePDU does not exceed the ePDU's capacity.
Installation ! IMPORTANT The ePDUs have two separate receptacle groups. The ePDU segments are protected separately by circuit breakers on the front panel. To install the ePDU: 1. If optional circuit breakers are installed, verify that each circuit breaker on the ePDU is in the OFF position. The indicator LED should be off. 2. Plug the equipment power cords into the ePDU output receptacles. Distribute the load evenly between the segments. 3.
Installation Branch Circuit Protection Caution Circuit breakers are not provided on all models; breakers are optional.

Chapter 4 Operation This chapter describes operation of Eaton T2235 Series Automatic Transfer Switch (eATS) Enclosure Power Distribution Unit (ePDU) models, including the following: l Indicators, circuit breakers, and power outlets l Auto-transfer of primary input power to secondary input power l Electromagnetic interference/radio frequency interference (EMI/RFI) filtering option l Surge suppression Indicators The T2235 Series eATS ePDU models use six LED indicators to convey the following: l Indi
Operation Circuit Breakers Circuit breakers protect the power controller and all devices connected to it from fault conditions, such as a short circuit or an overload. Circuit breakers are optional for ePDUs with less than 30A input. However, circuit breakers are mandatory for ePDUs with 30A input or greater. ! IMPORTANT If a supplementary protector is used in the ePDU instead of a listed circuit breaker, additional branch circuit protection is required down-line from the power source to the ePDU.
Operation Figure 6 shows the EMI Filtering diagram. Line Load Figure 6. Filtering Diagram Surge Suppression Some T2235 Series eATS ePDU models provide line-to-neutral metal oxide varistors (MOVs), and some models provide line-to-line MOVs as delivered from the factory. See Chapter 6, “Specifications” on page 21 for more information. Table 4 shows specification data for Surge Protection Devices (SPD), formerly referred to as Transient Voltage Surge Suppressors (TVSS). Table 4.
