Clearances and orientation
| Installation clearances | PDF page 20, general prose: To ensure proper operation and long battery life, please make sure to leave at least 300mm of cooling space around the battery. Shading or insufficient space for heat dissipation will result in high battery temperatures, which may cause unplanned shutdowns and significantly shorten the service life of the battery.; PDF page 20, single-cluster 3D illustration: ≥50mm arrows, ≥300mm arrows (including top), 50mm between bases. Other direction labels are not invented.; PDF page 20, labeled three-cluster plan: Battery back clearance ≥300mm; Battery side clearance ≥300mm; Clearance between battery clusters ≥300mm; Battery front clearance ≥800mm; between bases 50mm.[1]Needs confirmation |
|---|---|
| Mounting orientation | PDF page 21: Position the base (Item R) on the floor at the distance shown in the figure below, and verify levelness using a spirit level.; PDF page 21: When placing the base, it is necessary to ensure that the distance between the bases is 50mm; Otherwise, the base-fixed metals (Item T) in Step 2 will not be able to be installed.; PDF page 22: Two methods are available for handling the battery pack: Method 1: Screw the solid handles (Item S) from the Accessory Package into the pre- tapped mounting holes on the battery pack. Method 2: Use the integral handle slots molded into the battery pack housing.; PDF page 22: By moving the position of the battery pack, the raised sphere on the base will bounce up and restrict the movement of the battery pack.; PDF page 22: Use front fixed sheet metals (Item P) to secure the battery pack and the base. Fix the battery packs at the bottom of the two columns using base-fixed metals (Item T).; PDF page 23: Select the appropriate stacking configuration based on the quantity of battery packs, then handle and stack the High-Voltage Control Box and all CQ16 in accordance with the selected arrangement. ② The upper and lower two battery packs are fixed with fixed grounding metals (Item E). ③ Connect the fixed grounding metals (Item E) between all the batteries. Note： Position the High-Voltage Control Box on the top of the battery packs in the rightmost column. The back of the battery also needs to be fixed.A total of four fixed grounding metals (Item E) are required between every two battery packs for fixation. The fixed grounding metals have the function of grounding connection. Please connect all the fixed grounding metals.[1] |
Grounding
| Grounding | PDF page 8: Please ensure that all the batteries are grounded properly.; PDF page 23: The upper and lower two battery packs are fixed with fixed grounding metals (Item E).; PDF page 23: Connect the fixed grounding metals (Item E) between all the batteries.; PDF page 23: The back of the battery also needs to be fixed.A total of four fixed grounding metals (Item E) are required between every two battery packs for fixation.; PDF page 23: The fixed grounding metals have the function of grounding connection. Please connect all the fixed grounding metals.; PDF page 26: Route communication cable (Item J) through right-side cable duct. Step ２ Route grounding cable (Item I) through right-side cable duct and secure with screw. Ensure firm and reliable connection. Step ３ Secure wiring cable with cable ties (Item C). Step ４ Reinstall decorative cover.[1] |
