Safety Instructions
The EPIC®SOLAR 4PLUS connector is not suitable for mating and unmating under load.
De-energize the circuit by appropriate measures, e.g. at the inverter. Disconnecting and also
plugging in is possible without load, while voltage is present.
EPIC®SOLAR 4PLUS connectors are intended for connecting stationary photovoltaic systems.
They are suitable for fixed installation in dry and damp rooms, as well as outdoors. EPIC®
SOLAR products are not suitable for underground installation.

connection
Mated connectors are IP68 protected (1m/10h). Continuous ooperation under water, e.g.
water on the roof skin of a flat roof is not possible.
EPIC®SOLAR connectors may only be assembled using tools and aids specified by Lapp. The
cable may only be connected to the connector by trained electricians. To protect the installer
from the danger of the electric current, the connector must be made floating on all sides during
installation.
Unplugged connectors must to be protected against ingress of dirt and moisture. Before
plugging together, make sure that the mating area is free of any dirt.
Note :The PV Connectors EPIC SOLAR 4 Plus are not rewireable.
Defective connectors can be replaced by new connectors of the same type and
connection cross-section, complying with all requirements of this installation
instruction and having ensured that the cabel is without voltage and not under load.

Preparing the cable
Cut the cable cleanly - the strands must not have any oxidation or contamination.
Stripping the cable
Stripping length: depending on the table (see table above!).
The insulation must be removed clean and competed. No stranded wires may be cut off

Crimping the contacts
Check that contact and cross-section match.
Insert the contact with the opening facing upwards into the EPIC®SOLAR Crimping tool.
Insert the wire completely into the crimp area of the contact.
The cable is pushed forward until the insulation strikes the
crimp receptacle of the contact. In this way a supernatant
of at least 2 mm is ensured.
Completely squeeze the tool until the trigger lock releases the tool again.
Remove the crimp and visually check that all strands are completely enclosed.
The strand supernatant after crimping is at least 2 mm.

Mounting
Insert the crimped contact into the opened cable gland until the contact clicks into place.
Lightly pull the cable to make sure that the contact is properly engaged.
Turn cap nut “hand-tight” (4,5 Nm) – finished. Spanner size 19.
(EPIC®SOLAR 4PLUS F)
Connecting and Disconnecting
Before plugging in, check the plugging area for possible soiling and clean it if necessary.
Especially the O-ring on the female connector must be absolutely clean. Trapped moisture
must be removed. Plug EPIC®SOLAR 4PLUS, male and female together until the snap-in hooks
are fully engaged on both sides.
To disconnect, press the latching hooks on both sides with the standard pliers (article
3115160) and pull them apart carefully but firmly.

Laying the cable
The cables must be firmly laid in the photovoltaic system, securely fastened and the minimum
bending radius must not be undercut. The cable must be led straight out of the connector at
least L=50 mm. The bending radius Rmin must be at least 10x cable diameter.
