Functional Description

5461-640 is an auxiliary power supply developed by Woodward. It is specifically intended for use in Class I, Division 2 hazardous locations or non-hazardous locations. Class I hazardous locations refer to areas where flammable gases, vapors, or liquids may be present. Division 2 indicates that these hazardous materials are present under normal operating conditions only. Therefore, the power supply is suitable for use in environments where there may be a potential for the presence of flammable substances. Before any installation or removal of the power supply, it is crucial to ensure that the input power is completely disconnected. This precautionary step ensures the safety of personnel and prevents any potential electrical hazards during the process. When installing the power supply, it is crucial to adhere to the wiring methods specified for Class I, Division 2 locations. These wiring methods are designed to mitigate the risk of electrical sparks or ignition in hazardous areas. Following the prescribed wiring methods ensures compliance with safety regulations and reduces the possibility of accidents or incidents.

Features

• Cable Connection: The power supply chassis has a designated cable connection point located near the back of the upper side of the chassis. This connection allows for the attachment of the power supply ribbon cable. It is essential to connect the cable properly to ensure reliable power transmission.
• Ribbon Cable Length: The power supply ribbon cable provided is one foot long. Due to this limited length, the TMR Power Supply Chassis needs to be positioned directly beneath either the A or C Kernels of the TMR Main Chassis. This arrangement allows for the appropriate connection and placement of the power supply system within the overall TMR configuration.
• Input Power Disconnect: It is important to note that the control's power supplies lack input power switches. Therefore, during installation or servicing, a means of disconnecting the input power to each main power supply must be provided separately. This can be achieved using a circuit breaker that meets the required specifications or by incorporating a separate switch with appropriate ratings. This precaution ensures safe power disconnection when necessary.
• Power Supply Ribbon Cable Connection: The power supply ribbon cable connects to a connector located on the back underside of the TMR Main Chassis. This connector is positioned beneath the A and C Kernels and allows for connection in either direction. In other words, the cable can be connected to the connector in either orientation, providing flexibility during installation. It is also possible to connect two TMR Power Supply Chassis to each of these connectors, allowing for increased redundancy and power supply capacity.
• By taking advantage of these features, the TMR Power Supply Chassis can be seamlessly integrated into the TMR system configuration. The cable connection points, input power disconnect options, and flexible ribbon cable connectors ensure proper power supply distribution, easy installation, and enhanced system reliability.
