- Page 10 Removing the Rubber Rings from the Crimping Module Use scissors to cut off the joints of the rubber rings to remove them. All rubber rings are removed in the same way. Remove the corresponding rubber rings strictly according to the cable diameter range, and ensure that the crimping module is not damaged.
- Page 11 Installing the AC Output Power Cable • The cable outer diameter can be measured using the ruler sticker in the maintenance compartment. • Ensure that the AC output power cable is secured. Failure to do so may cause the solar inverter to malfunction or damage to its terminal block by issues such as overheating.
