Assembly instructions for connector of PV-R4C/...Especially


During self assembly ,parts and tools other those stated by R&X are used or if the preparation and assembly instructions described here are disregarded then neither safety nor compliance with the technical data can be guaranteed.

For protection against electric shock ,PV Connectors must be isolated from the power supply while being assembled or disassembled

The end product must provided protection from electric shock

Unplugging under load:PV plug connections must not be unplugged while under load.They can be placed in a no load state by switching off the DC/AC converter or breaking the AC circuit interrupter.Plugging and unplugging while under voltage is permitted

Disconnected connectors should be protected from dirt and water with sealing caps.

Plugged parts are watertight IP68

Assemble the cable and connector

(Picture 1&2)

Push the crimped contact into the socket resp.Plug insulator until it engages .

Pull lightly on the lead to check that the metal part has engaged.

Screw on the cable gland ,hand-light,with the tools PV-STX,tightening torque about:2.2Nm.




Mount the connector together until they engage.

Check correct engagement by Pulling on the coupling.



(Picture 4&5)

Compress the two snap-in springs by hand or with PV-STX tool and separate the coupling
