If any damage is observed contact the carrier immediately. Continue the inspection for any internal damage. In the unlikely event of internal damage, inform the carrier and contact Alpha Technologies for advice on the impact of any damage.
6. Installation Only qualified personnel should install and connect the power components within the Alpha power system. For the battery installation, refer primarily to the manufacturer’s manual. Frequent reference is made to drawings located at the rear of this manual. Layout and schematic drawings are pro- vided with the power system.
Page 35
6.3.1 Installation Verify that all battery breakers, DC circuit breakers, and fuses on the distribution panels are either in the OFF position or removed. Apply a corrosion-inhibiting agent, such as NO-OX-ID “A”, on all battery terminal connections. 1. If required, assemble the battery rack and the cells or mono-blocks as per the installation instructions supplied with the batteries.
Page 36
After assembly, number the batteries and take “as received” readings, including specific gravity, cell voltage, and temperature. Designate one cell as the pilot cell. This is usually the cell with either the lowest specific gravity or volt- age. Refer to the manufacturer's literature for guidelines. See the following table for typical maintenance report: Company: _____________________________________________________ Date: _____________________ Address: _________________________________________________________________________________ Battery location and/or number:_______________________________________________________________...
6.4 Power System Assembly and Mounting The power system must be mounted in a clean and dry environment. Sufficient free space must be provided at the front and rear of the power system. This is to meet the cooling requirements of the rectifiers and to allow easy ac- cess to the power system components.
7. Wiring This chapter provides cabling details and notes on cable sizing for DC applications with respect to the product. WARNING! Ensure that the power is switched off by switching off rectifiers and removing battery line fuses, turn off battery breakers before attempting work on the wiring. Use a volt- meter to verify the absence of a voltage.
7.2.1 Frame Ground The power plant frame must be connected to the MGB or FGB. This connection is necessary for personnel safety and to meet many telco-grounding requirements. Use #2/0 for frame ground. Remove paint in lug contact area to ensure a good electrical connection. Connection to Overhead Trays The rack upper crossbar (figure ) has three-five 5/8"...
7.3.2 CAN Bus Termination - 4.0kW Rectifier Shelf The CAN bus provides a communication path between the controller and rectifiers. In a single bay, the CAN bus cabling is daisy-chained from the L-ADIO, to the top rectifier shelf. The cable is then daisy-chained from the top shelf, to lower shelves, in sequence.
7.4 AC Wiring 2.4kW Rectifier Shelf 7.4.1 AC Feeder Protection/Sizing To maximize system reliability, each feed should have a dedicated protection feeder breaker located at the AC dis- tribution panel. The feeder breaker can also act as the disconnect device for the connected modules. Refer to the specifications at the back of this manual for Alpha breaker and wire size recommendations.
7.4.2 Can Bus Termination - 2.4kW Rectifier Shelf Two CAN serial ports (modular jacks with offset latches), are provided for communications with Alpha Cordex recti- fiers and other CAN-enabled equipment. These are located on the left-sed of the rectifier shelf as viewed from the front.
7.5 DC Wiring WARNING! Leave cables or busbars disconnected at the battery and verify the output polarity using a voltmeter. Make battery connections only after all other wiring is completed. DC output wire must be UL approved XHHW or RHH/RHW (for Canadian users, RW90 Type). Control and sense wires must be UL approved Style 1015 (for Canadian users, TEW type).
7.5.3 Connecting the External Battery Alarm These instructions apply to the following Alpha's 0912xxx-xxx series of battery bays. 1. Connect a #18AWG wire (black recommended) to the terminal block "ALARM" on the battery bay. 2. Connect to the L-ADIO; D2 (pos. 26). 3.
7.6 Dual Voltage Conversion The staged tier is split in four sections. It is factory configured to supply two voltages: -48 Vdc on the left section (positions 1 through 12), and +24 Vdc on the right three sections (positions 13-24). The +24 Vdc sections are joined by a link bar (see Figure 25).
7.7 High Capacity Breaker Alarm and Shunt Wiring 1. Connect the alarm wire (-HOT) from position NC on the breaker, to one of the available digital inputs on the L-ADIO. 2. Add a (+ RETURN) jumper from the digital input. 3.
7.8 Signal Wiring 1. Use the Form C relay contacts on the L-ADIO to extend various alarm or control signals to an external site monitor. Figure 29 shows the L-ADIO module layout table F lists the factory default settings. 2. Use 0.129 mm² (#26 AWG) or larger wire. 3.
7.8.2 Analog Inputs WARNING! Ensure that the correct polarity is used for all input cable terminations. The analog input channels are used to monitor various types of electrical signals. Some of the analog channels are reserved for specific signals, while others are designated as general-purpose inputs, which accommodate various types of analog signals.
8. System Startup After completing the system installation and power system wiring, perform the following startup and test procedure to ensure proper operation. 1. Visually inspect the installation thoroughly. 2. Verify: AC input power is off. Batteries are disconnected. All breakers are off and no fuses installed if any loads are connected. All power modules are removed from the shelves.
