Safety Instructions
The Connector EPIC®SOLAR 4 PLUS is not able to be connected or disconnected under load.
De-energize the circuit by appropriate measures, e.g. at the inverter. To disconnect and to
connect without load, under voltage, is possible.
EPIC®SOLAR 4PLUS Connectors are intended to connect stationary photovoltaic systems.
They are suitable for fixed installation in dry or damp rooms, as well as outdoors. EPIC®SOLAR
products are not suitable for laying into earth.

Designation LAPP KABEL H1Z2Z2-K
Cable Code H1Z2Z2-K
Rated cross-section : 4,0 mm²; 6,0 mm²; 10,0 mm²
Rated Voltage : AC U0/U 1,0/1,0 kV
DC 1,5 kV
max. Voltage : DC 1,8 kV (Conductor / Earth)
System without Earth Connection
Mated connectors are IP68 protected, 1m 10 h. A permanent use under water, e. g. water on
the roof of a flat roof is not possible.
EPIC®SOLAR connectors shall be mounted only with tools and accessories specified by Lapp.
The connection of the cable at the connector must be performed by qualified electricians. To
protect the installer from the danger of the electric current, the connector must be made
floating on all sides during assembly.
Unplugged connectors must 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 rewirable.
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 connector is without voltage and not under
load.

Crimping the contacts
Check that contact and cross-section fit together.
Insert the contact with the opening facing upwards into EPIC®SOLAR Crimp-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, the
supermatent is insured at least 2 mm.
Completely squeeze the tool until the trigger lock releases the tool again.
Remove the crimp ad check visually if all strands are completely enclosed.
The strand supernatant after crimping is at least 2 mm.

Connecting and Disconnecting
Before plugging in, check the plug-in area for any dirt and, if necessary, clean it. Especially the
O-ring on the female connector must be absolutely clean. Remove moisture. Connect EPIC®
SOLAR 4 PLUS, male and female until the snap-in hooks are completely 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.
