4. SAFETY PRECAUTIONS
Products must be assembled and installed by
qualied personnel, ensuring all safety regulations
are followed. For protection against electric
shock, please ensure the system is not energized
during installation. Do not disconnect under load.
Ensure that the AC and the DC sides are both
disconnected and the system is not energized before
disconnecting.
Use only the tools and components listed in this
installation manual. Follow the instructions as stated
in this manual. Do not alter or willingly damage the
product in anyway.
• Sealing cap must be used on disconnected
connectors to prevent dust ingress.
• Connectors are IP68-rated when mated.
• Do not place connector directly on roof surface.
• CAUTION1 :
The exposure to or direct contact with chemicals or
oils of T4 product may cause corrosion, degradation
of performance, or cracking of the product, thus
such exposure or direct contact should be strictly
prohibited during the process of product manufactu-
ring, transportation, installation and application.
It is the user's responsibility to validate any chemi-
cal that may come into contact with or used in any
of the processes mentioned above,to ensure that
such chemical will not affect the performance of T4
products.

6. CONNECTOR & WIRE ASSEMBLY STEPS
STEP 1:
VISUAL INSPECTION OF CONNECTOR
FEMALE CONNECTOR
a. Sealing ring should t cleanly in the slot and
not be warped or distorted.
b. The two plastic clasps should be intact.
c. Female connectors should not be
obstructed by foreign objects or water.
d. Plastic components should not be cracked.
e. No damage should be visible on the cable.
MALE CONNECTOR
a. Male connector should not be obstructed by
foreign objects or water.
b. Plastic components should not be cracked.
c. No damage should be visible on the cable.

STEP 2:
STRIP THE INSULATION OFF THE CABLE
Using the wire stripper tool, remove the insulation
from the cable. Ensure that 7.5 mm of cable are
exposed, and that the wire strands are not damaged
during the process of stripping the insulation.
STEP 3:
CRIMP THE CONTACT
Place the contact around the bare section of the
stripped wire. Crimp the contact using the wire
crimping tool. The crimped contact should withstand
pull forces of ≥310 N.
STEP 4:
INSERT THE CONTACT
Push the crimped contact back into the connector until
you hear a click. Lightly pull the wire to ensure the
metal components of the connector are engaged.
STEP 5:
TIGHTEN THE CABLE GLAND
First, tighten the gland by hand, then use the
disconnect tools to tighten the gland to the connector
until it clicks, ensuring that it is locked. When tighteng
the male connector, please use aligner available on
the disconnect tool in order to ensure the pin is not
skewed.
STEP 6:
MAKE CONNECTION
Check the appearance of the connectors before
connecting them together. The sealing ring should
be in the slot with no warping or distortion. The
plastic clasps should not be damaged or broken. The
connectors should be free of moisture and foreign
objects. Plastic parts should not be cracked. Wire
should not be frayed or damaged. When attaching,
insert the connectors into each other until you hear a
“click”. Once attached, gently pull on the connectors to
ensure they are rmly connected and cannot be easily
disconnected by hand.
STEP 7:
VISUAL INSPECTION OF THE CONNECTION
To check the connection, ensure that you cannot see
the sealing ring. The gap between the connectors
should be less than 0.5 mm.
7.5 mm

7. THE CORRECT CONNECTION
Please refer to the detailed instructions of the
minimum bend radius given by the cable
manufacturer
8. DISCONNECTING THE CONNECTORS
The mated connectors can only be disconnected by
using the disconnect tools.
Insert the clasp of the disconnect tool in the slots of
the male connector, and the female connector will
automatically get disconnected .
