The two MC-4 Connectors provided in the optional “MC4-2” Kit are connected to the bare ends of the two wires of
one of the two Connecting Wires Kit “SWC-20-2“ as follows:
1. Cut the two SWC-20-2 wires to the desired lengths depending upon the distance between the solar
panels.
2. Strip 0.25” of the insulation at the ends.
3. Establish the correct polarity by tracing the wires back to the solar panel, if necessary.
4. Crimp the male and female contact inserts (2 and 5 of Fig. 2) to the bare ends of the wire with the
help of special purpose crimping tool meant for the MC4 connectors.
5. Install the contact inserts inside the housing of the MC4 connectors and tighten the strain relief / seal
(7 of Fig. 2) fully to ensure a watertight seal.

The SCW-20-2 Solar Panel Connecting Wire Kit (Fig. 1) contains (2) 20 ft wires pre-assembled with a male and female
MC4 connector on one end of each; the other end is blunt. These wires are used to connect the output of the solar
panel to the various components of a solar installation. The wire used has the following specifications:
• Size AWG #12, insulation rating 600V
• Sunlight resistant, photovoltaic wire, UL listed
Note
. This kit can be used only if the output wires of the solar panel are terminated with MC4 Series of Male and Female Connectors
described below (like in Samlex branded Solar Panels).
1. MC4 Female connector (marked “+”)
2. MC4 Male connector (marked “-”)

GENERAL INFORMATION ON MC4 CONNECTOR SYSTEM
An MC4 Connector System consists of male and female connectors. This type of connector system is easy to install
and uses “snap-in” type of safety locking clips to lock the two mating connectors, thereby, avoiding unintentional
disconnection. Also, the mating contacts are sealed against ingress of dust and water. Specifications are as follows:
• Contact diameter Ø 4 mm
• Maximum rated current - 30 A
• Maximum system voltage - 1000 V
• Degree of ingress protection when connected and properly locked - IP67
• Temperature range 40°C to +90°C
• TÜV Rheinland – type approved
MC4 Connectors (Fig. 2)
The MC4 Connectors mentioned in this manual have been designated “Male” and “Female” based on the
characteristics of the mating contact inserts inside the terminals.
In the MC4 Male Connector (1 of Fig. 2), the internal mating contact insert (2, Fig. 2) is a male pin. It has two slots
(3 of Fig. 2) for insertion of the two “snap-in” type of locking tabs (6 of Fig. 2) of the MC4 Female Connector (4 of
Fig. 2) for firm mating connection. This connector is marked "-"
.
