Page 8: Minimum Specifications For Aes Rackmount Battery Energy Storage Systems
4.1 Minimum Specifications for AES RACKMOUNT Battery Energy Storage Systems To increase system capacity, install AES RACKMOUNT Battery Modules in a parallel battery bank configuration. Overall battery energy storage system capacity must be correctly sized to meet the requirements of the load and account for the following: • Total Continuous Charge Current • Total Peak Current • Total Continuous Discharge Current The total charging capacity of all charging sources in the system should not exceed the Continuous Charge Current operating limit of all the Battery Modules in the system or the limits on the Battery Module Combiner. Exceeding one of these limits will cause either the BMS in the Battery Modules to trigger over-current protection and disconnect or trip the breaker on the Battery Module Combiner. The charging system's maximum Continuous Charge Current must either be below the operating limit of installed Battery Modules or curtailed . The sum of all the Peak Current values for the attached loads must be less than the Peak Current value of the BESS, including inrush current values for any motors and surge values for any inverters. -

5.2 Attaching the Brackets and Side Arms onto the Battery Module Assemble a single Quick Stack Rack and lower the AES RACKMOUNT battery module into the front opening . 1 . Line up the holes of the Side Arms with the screw thread ends protruding from the Front End Bracket and Back End Bracket . Figure 3. Quick Stack Rack Assembly 2 . Screw on the M4 nuts (torque 2.5 to 3 Nm [1.85 to 2.2 ft-lbs]) to secure the Side Arms to the Front End Bracket and Back End Bracket . Once the single Quick Stack Rack is constructed, flip it vertically so the Back End Bracket is on the ground . -

3 . Using a two-person lift, slowly lower the Battery Module through the Front End Bracket and then through the Back End Bracket . 4 . Secure the side flanges of the AES RACKMOUNT Battery Module to the Front End Bracket using the mounting screws that came with the Battery Module (torque of 8 to 10 Nm [5.9 to 7.4 ft-lbs]). 5 . Repeat as necessary for all the AES RACKMOUNT Battery Modules. NOTICE EQUIPMENT DAMAGE When lowering the AES RACKMOUNT battery module through the Quick Stack Bracket, do it slowly to minimize scratches to the finish and to the safety and specification decals. Failure to follow these instructions may result in equipment damage. NOTE This assembly method is not suited for the Battery Module Combiner due to the interference caused by the pre-installed battery cables. 5.3 Attaching the Brackets and Side Arms onto the Battery Module Combiner 1 . -

3 . Slide the Back End Bracket onto the Battery Module Combiner. Note the screw thread ends protruding from the sides of the Front End and Back End Brackets . 4 . Attach the Side Arms so the holes line up with the screw thread ends. 5 . Screw on the M4 nuts to secure the Side Arms with a torque of 2.5 to 3 Nm (1.85 to 2.2 ft-lbs). NOTE This assembly method can also be used to attach the Quick Stack Rack to battery modules. 6. INSTALLATION When using the Quick Stack Rack, the Battery Module Combiner should be placed in the middle of the stack so the battery cables can reach the terminals of all the Battery Modules . 6.1 Location The Quick Stack Rack must be installed and used indoors in a dry location on a flat surface with at least 1U (44.45 mm, 1.75 inch) clearance space above and on both sides of the Battery Modules and Battery Module Combiner. Provide enough space at the back of the modules to accommodate DC cables. For more installation details, refer to the (805-0043) AES RACKMOUNT Installation and Operation Manual and the (805-0055) AES RACKMOUNT Battery Module Combiner User Manual. 6.2 Stacking Battery Modules with the Battery Module Combiner CAUTION TIPPING HAZARD •... - Page 13 Before stacking Battery Modules, the Front End and Back End brackets and the side arms must be attached to all Battery Modules and the Battery Module Combiner. 1 . As a base, place a Battery Module, with brackets attached, in the final installation location . 2 . Stack a second Battery Module on top of the first Battery Module. Figure 6. Align pins on the lower unit’s brackets with holes in the upper unit’s brackets 3 .

APPENDIX A1. AES RACKMOUNT BESS Commissioning Checklist Use this checklist to confirm the correct installation and function of the AES RACKMOUNT BESS during the commissioning of a complete energy storage system. This checklist is only for the installation and operation of the AES RACKMOUNT BESS. Further system-level functionality checks and tests must be performed once the full system is interconnected with the battery energy storage system to complete commissioning . Battery Installation PROCEDURE CHECK 1 . Ensure that ALL Battery Modules and the Battery Module Combiner are securely mounted to the Quick Stack Racks. Verify that: • All FOUR screws are tight on each flange of the Battery Modules and Battery Module Combiner. 2 . Ensure that the bottom of all four feet is making solid contact with the mounting surface . 3 . Ensure that the Quick Stack Rack is suitably anchored to the wall or ground. 4 . Confirm the wiring from the Battery Module Combiner to Battery Modules. - Page 17 Battery Operation Verification The safety functions inside the Enclosure to protect the batteries are solely provided by each UL 1973 certified AES RACKMOUNT and its integral BMS battery module (Battery Management System). No communication with any equipment external to the AES RACKMOUNT BESS is needed to operate the battery module’s integral protection functions . Verify the items below to confirm that the protection functions of the battery modules are working correctly. PROCEDURE CHECK 1 . Confirm that each battery breaker is OPEN, and turn on each Battery Module through the push button. Verify that: • The battery status LED turns ON and pulses AMBER. NOTE: • If the LED does not turn ON, there is an issue with the battery module. Contact Technical Support. • If the LED turns GREEN, check if the battery breaker is OPEN. If it is open, contact Technical Support. • If the LED turns RED, there is a fault present. Use LYNK Access software to find details about the fault. 2 . CLOSE each battery breaker, one by one. ...
