Protection
| Fuse or breaker | PDF page 16: Battery protection: Internal Short Circuit, Over Voltage, Over Current, Over Temp, Under Voltage.; PDF page 34: The battery system includes an automatic low-temperature protection feature. it proactively manages. The battery to maintain adequate charge, extending standby time when temperatures drop.; PDF page 35: The CQ battery system has a non-reset table function to stop operation when one or more cells in the battery system deviate from the operating region during operation. This feature shall not be a user reset table or allow for automatic reset. Please ask after sales for help.[1] |

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.[1] |

Communication
| Communication ports | PDF page 17: CQ16 module interface: BAT-: BAT negative terminal; PDF page 17: CQ16 module interface: BAT+: BAT positive terminal; PDF page 17: CQ16 module interface: Fan: Ventilation and heat dissipation; PDF page 17: CQ16 module interface: COM1: Connection position of battery module communication and power supply input; PDF page 17: CQ16 module interface: COM2: Connection position of battery module communication and power supply output; PDF page 17: CQ16 module interface: LED: Battery pack status display; PDF page 24: Use communication cable（Item O）to connect the first battery "INCOM (white)" from the high-voltage box "OUTCOM (yellow)". The communication cable (Item O, U) between other battery packs are connected in sequence from "OUTCOM" to "INCOM". (Refer to the illustration below: Following the direction indicated by the arrows, insert the communication cables harness in the color sequence “yellow, white, yellow, white...”.) ② Use cable ties (Item C) to fix the cable. Note: When connecting cables, observe the installation diagram and pay attention to the direction of the communication cables. Otherwise, the products may not work properly. All wiring harnesses and brads supplied by FOX.; PDF page 29: For CQ 16 Green LED Red LED Batteries Status On for 0.5s, Off for 0.5s On for 0.5s, Off for 0.5s Running in boot On for 0.1s, Off for 0.1s On for 0.1s, Off for 0.1s Upgrading On for 1s, Off for 1s Off Normal Working Off On for 1s, Off for 1s Alarm[1] |
