This window requires no user operation. In split bypass configuration, the static bypass and maintenance bypass share the same independent bypass power supply. Seismic anchor 5 M10×30 sems screw 4 pcs Seismic anchor 3 Figure 8-13 Fixing seismic anchor 5 onto seismic anchor 3 6. The grounding wires shall be tied up reliably to prevent the loosening of the grounding wire tightening screws when the grounding wires are pulled. These improvements contribute significantly to a smaller footprint and more efficient operation without sacrificing the high levels of reliability. If you want to quickly view the content of pages found on the following pages of the manual, you can use them.Next
The menu keys are described in Table 4-5. The input dry contact voltage is 12Vdc, and the current is 20mA. When the time has expired, the load automatically transfers to the bypass A transfer to bypass occurred due to a large step load. If the load is not ready to receive power, please disconnect the downstream load switch, and stick a warning label on the connection point of the load. Please follow the precautions for high voltage operation. Profess Summary of the content on the page No.
Warning: high earth leakage current Earth connection is critical before connecting the input supply including both mains supply and battery. When all the blocks are connected together, the battery string voltage can be up to 432Vdc. Wiring according to Figure 8-8, pack the cables in order. Two connection modes are available: top cable access, bottom cable access. Procedures for manual maintenance self-test 1.
Warning The voltage of the dry contact signal connected to J5 backfeed protection dry contact port may be dangerous. For systems under different conditions environment, load rate, and etc. Check to ensure that the battery terminals have no damage or heat generating trace, and the battery enclosure and terminal shields are intact. This chapter provides information relevant to these types of communication. Availability is also enhanced with a triple mode battery charger that enables fast battery recharge.Next
Designed for optimized performance with the same high efficiency at 40% utilization as at 100% utilization. Note The rectifier input and bypass input must use the same neutral line. The rectifier will start automatically when the overtemperature fault disappears five minutes after the disappearance of overtemperature signal. In this situation, the bypass will directly supply the critical loads through the maintenance bypass. Pressing any menu keys F1 ~ F5 restores the default screen. Certain clearance shall be maintained between the battery top and the upper layer to facilitate the monitoring and maintenance of the battery.Next
The maintenance self-test does not update the battery curve table. Table 3-9 provides the models and installation positions of the optional cards. If this is the case, remove the earth connection. Figure 5-3 Disconnecting terminals of the internal battery 8. However, during the installation design of the battery, temperature rise shall be taken into account, and enough room shall be reserved to ensure good ventilation.Next
There are no user-serviceable parts behind covers requiring a tool for removal. Refer to Warning: high earth leakage current before Contents. Periodical self-test: self-test period can be configured via the Emerson setting software. If the load is less than 20%, the automatic discharge cannot be executed. Note When the load is supplied by the bypass or maintenance bypass, the power supply quality will be uncertain. Sometimes, it is necessary to connect several strings of battery in parallel.Next
The batteries shall be installed from the bottom layer and from bottom to top, so as to avoid a too high gravity center. The auxiliary contact requirement of the external output switch: Auxiliary contact of external bypass closed upon switch closed 2. After the connection is completed, the screw connections between all the terminals and the batteries shall be calibrated. Remove the adjustable feet Adjustable foot 4 pcs Adjustable foot 4 pcs Figure 8-9 Removing adjustable feet 2. If the load is not ready to receive power, disconnect the downstream load switch, and stick a warning label on the connection point of the load. Maximum boost charge protection time To protect against the battery overcharge damage caused by long time boost charge, a protect time setting is essential. Only Emerson-authorized engineers shall carry out the installation.Next
