Solution

● PV module’s ribbon alignment must be complied with JB’s mounting hole of the terminal base.

● Adhesive and sealing compound, Potting glue must be applied by using specific type and specification. Make sure JB will be fixed in the correct position and reliable sealant. The potting glue level should be over the top surface of Diodes and terminal base. In order to avoid electrical shock risk.

● Don’t move PV module or JB before adhesive and sealing compound or potting glue solidify.

● Ensure soldering between Ribbons and terminal reliably in order to avoid missing soldering or false soldering. The soldering operators must be professionally trained. More soldering time will cause the diodes damaged.

● Adopt anti-static protection solutions when touch or solder JB.

● Make sure the connection method between JB and PV module in the correct polarity. Otherwise, Wrong connection will cause fire.

● PV module manufacturer should inspect the diodes of JBs before shipment since the diodes might be damaged by heat temperature or the static shock.

● Installation or maintenance should be operated by the professional personnel.

● For protection against electric shock, while being assembled or disassembled, make sure connectors isolated from the power supply.

● Don’t connected or disconnected under load.

● During the assembly process, keep the connector away from any corrosive materials.

Attention

1. Handle with care during transportation without damaging the product.
2. When installing the junction box, make sure that the solar panel is not working and that the positive and negative rails cannot be touched at the same time to avoid electronic shock and diode interruption.
3. Do not connect the positive and negative of the same junction box at any time.
4. Except for maintenance, do not plug and unplug the positive and negative connectors frequently, otherwise the sealing performance will be reduced.
6. During installation, silicone shall be evenly coated on the base of the junction box to prevent leakage.
7. The rubber shall be kept clean and free of adhesive during assembly, otherwise the efficiency of the panel will be affected.
8. PV junction box and connector shall not touch paraffin, such as oil, lubricant, electroslag and other paraffin substances
