WARNING
· The DC cable should be prepared by the customer. Recommended specifications: · Type: single-core outdoor copper cable · Conductor cross-sectional area S: S=6mm2 or S=16mm2
· When the cross-sectional area range of the conductor is 6mm2, a 6mm2 DC connector (included in the deliverables) should be used. The drawing force of the cable after crimping should be greater than 500N. DC cables in this range can only be used to connect a single battery system. Do not cluster battery systems together as this may result in damage to the system.
· When the cross-sectional area range of the conductor is 16mm2, a 16mm2 DC connector (included in the deliverables) should be used. The drawing force of the cable after crimping should be greater than 500N.
· It is recommended to use a YQK-70 hydraulic plier to crimp the DC terminal of the battery. When the cross-sectional area of the conductor is 6mm2, the crimping dies with an "8" should be used, when the cross-sectional area of the conductor is 16mm2, the crimping dies with an "16" should be used.
· If the recommended hydraulic plier cannot be purchased, please choose the crimping tool according to the terminal size to ensure that the crimped terminals meet the usage requirements.
· Do not remove the cover of the DC cable port if the DC cable is not to be connected. Otherwise, the protection degree may be influenced.
