MC4 Assembly instructions
If, during self assembly, parts and tools other than those stated by MC 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 provide protection from electric shock.
The use of PVC cables is not recommended.
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 DC circuit interrupter. Plugging and unplugging while under voltage is
permitted.
It is unadvisable to use non-tinned cables of type H07RN-F, since with oxidized
copper wires the contact resistances of the crimp connection may exceed the permitted
limits.
Disconnected connectors should be protected from dirt and water with sealing
caps.
Plugged parts are watertight IP67. They cannot be used permanently under
water. Do not lay the MC-PV connectors on the roof surface.
See the MC catalogue 2 solar lines for technical data and assembled parts.
