It is recommended to mount the Backup Interface in a location protected from direct sunlight. 2. To allow proper heat dissipation, maintain at least a 4" clearance between the Backup Interface and other objects. 3. Position the mounting bracket against the wall/pole and mark the drilling hole locations. 4. Drill the holes and mount the bracket.
Chapter 2: Installing and Connecting the Backup Interface To install the conduit holder: 1. Insert the conduit holder in the space between the fins of the heat sink and the mounting surface. 2. Slide the conduit holder first to the left and then down to hang it on the short fin and the bolt affixed to the outer left fin. Figure 3: Installing the Backup Interface 3. Mark spots for drilling on the mounting surface. Figure 4: Marking drilling spots 4. Remove the conduit holder.
12 Installing the Conduit Holder 5. Drill two holes where marked. Figure 5: Drilling holes 6. Install the conduit holder. 7. Tighten the conduit holder to the mounting surface with two screws. Figure 6: Securing the conduit holder with screws 8. Tighten the conduit holder to the outer left fin with the supplied screw. Tighten the screw with a torque of 41 lb*in / 4.7 N*m. Backup Interface Installation Guide MAN-01-00728-1.
Chapter 2: Installing and Connecting the Backup Interface Backup Interface Interfaces The following figure shows the Backup Interface interfaces for operating and connecting to other system components. Install cable conduits, as required by local regulations. Figure 7: Backup Interface Interfaces Inverter AC inputs - AC cables from up to three inverters. Generator AC input - an AC cable from one external generator. Grid AC input - an AC cable from the grid.
14 Connecting the Backup Interface to the Grid and AC Loads Panel To connect to the Grid and Loads panels 1. Release the six Allen screws of the Backup Interface cover and remove the cover. NOTE Do not remove the internal plastic cover (dead front). 2. Install a conduit of the required diameter into the Loads conduit entry. Use the conduit holder to support the conduit. 3. Install a conduit of the required diameter into the Grid conduit entry. Use the conduit holder to support the conduit. 4.
Chapter 2: Installing and Connecting the Backup Interface 15 10. Connect the Line 1 and Line 2 wires to the grid's line terminal. Tighten the terminal screws with a torque of 200 lb*in / 22.5 N*. Figure 9: Connection to the Grid 11. Reinstall the plastic covers onto the loads terminals.
16 Connecting the Backup Interface to the Inverter d. Connect the cable wires to the 7-pin connector, as shown below, and reconnect the connector to the slot: Figure 10: Communication and 12V cables connection between Backup Interface and Inverter 3. Connect the cables to the Backup Interface: a. Pass the cables through the Com 1 conduit. b. Remove the 7-pin connector from the Backup Interface's communication slot. c. Connect the communication cable to the 7-pin connector, as shown above.
Chapter 2: Installing and Connecting the Backup Interface 17 2. Install a conduit of the required diameter into the Backup Interface's Inv1 conduit entry. 3. Pass the other end of the AC cable through the Inv1 conduit. Figure 12: AC connection between the Backup Interface and Inverter 4. Connect the L1 and L2 wires of the AC cable to the Inv1 terminal block, as shown above. Apply a torque of 22 in*lb (2 N*m). 5. Connect the Neutral wire to the Neutral bar. 6.
18 Connecting the Backup Interface to an External Rapid Shutdown Switch To connect to an External Rapid Shutdown Switch 1. Pass the cable form the switch through the Com 2 conduit. Figure 13: External rapid shutdown switch connection 2. Remove the 2-pin connector labeled EXT RSD. 3. Remove the short circuit jumper from the 2-pin connector. 4. Connect the cable to the 2-pin connector, as shown above. 5. Insert the 2-pin connector back into the EXT RSD port. 6.
Chapter 3: System Configuration 19 Chapter 3: System Configuration This chapter explains how to configure your Backup Interface using the SetApp mobile application. Before you begin, make sure the inverter firmware version is 4.8xx or higher. For information on updating your inverter firmware, refer to the Inverter Installation Guide. To set up communication with the Energy Meter 1. Make sure the StorEdge Connection Unit switch is OFF. 2. Switch the inverter ON/OFF/P switch to OFF. 3.
