Technical data
Products are a Type 6/6P enclosure ONLY when assembled with a Combined TC and Outdoor are rated cable type (such as
Listed TC/STOOW)

Strip the cable a length of 0.788 inches
(20 mm) (Fig. 2.1)
In case of screw connection
(PN: THB.385.xxx) strip the wires a
length of 0.315 inches (8 mm) and twist
them together (Fig. 2.1)
In case of piercing screw connection (PN:
THP.385.xxx) do not strip the wires (Fig.
2.2)
Connect the wires to the male connector
insert (or female connector insert) with a
screw driver.
Screws must be closed using a torque of
0.8 Nm for pressure wire
Insert the male connector insert in the
housing until it stop. Make sure the
connector insert’s protrusion match
with the housing’s cavity until you hear
a “click”
The female connector insert and the
male connector insert can be inserted in
both connector housings (male or
female) depending on the application
needs.
Firstly create a hole in the mounting
surface with Ø25 for the linear (Fig. 7.1)
and Ø20 for 90° version (Fig. 7.2)
Secondly, tighten the lock nut using the
appropriate tool to a torque of 2.5 Nm
and 4 Nm
Set-up of the female connector: (a)
Pressure nut, (b) locking nut,
(c) cable seal, (d) connector housing, €
connector insert (male or female)
