To install the Siemens PSX-12 power supply extender, follow these steps for safe and efficient operation. Before you begin, consult the PSX-12 instruction manual for detailed diagrams and safety information. First, ensure the dedicated circuit breaker for the PSX-12 is OFF, along with the battery circuit breaker. Set the HNET network address using the rotary dial switches, matching the setting in the Zeus Programming Tool. Next, disconnect all system power, beginning with the battery, then AC power. Mount the PSX-12 on the Mounting Plate (CAB-MP), aligning it with the threaded posts, either inside or outside the enclosure. The PSX-12 uses removable terminal blocks. The top terminal block is power limited, while the bottom connectors are not. Connect the earth ground to the PSX-12, complying with local codes and regulations. Wire the PSX-12 according to local codes and NEC regulations, ensuring proper conductor separation. Calculate the power supply load using the provided form to prevent overloading the PSX-12; ensure that the total 24VDC and 6.2VDC loads do not exceed the power supply output ratings. When connecting the battery, use 14 or 12 AWG wire, keeping the battery circuit breaker OFF. Connect the batteries using the provided quick disconnects, following the specified steps. By adhering to these guidelines and consulting the Siemens PSX-12 manual, you can ensure a secure and effective installation.
