regulations (e.g. IEC/EN 60079-14) apply.
1.2 When operating the device:
Ensure the operating instructions are made
available for the person in charge on
location at all times.
Observe these instructions, other working
instructions and national safety regulations.
Verify the implementation of safety
instructions.
2. Intended Field of Application
The Universal Explosion Proof LED Lighting, Model THT-L1219 is intended for using in gas explosive
atmospheres (Zone 1 and Zone 2 according to IEC60079-10-1) and dust explosion hazards (Zone 21 and Zone
22 according to IEC60079-10-2). The use in other potentially explosive atmospheres does not correspond to the
designated use and is therefore not allowed.
The apparatus is designed for using in indoor and outdoor environments.

Orderly assemble the O-ring (8), Washers (7) & (5) and Tube (6), and Screw tighten Pressure nut (4) with the
Body of Cable Gland by appropriate tool, 600 kgf-cm.
Screw and tighten the M4 Socket Set Screw (13), 24.5 kgf-cm.
Position the Nut Plate, then screw and tighten the 2 M4 screws provided, 24.5 kgf-cm.
Assemble the O-ring (2) with the Connector (3), and attach the Sleeve (1) with the Main Body (9).
Check the tightness of the Cable Gland and Top Cover, ensure the IP protection guaranteed. The Cable Gland
is assembled completely.
Assemble the Cable Gland by following procedure:
Step 1
Step 2
Make sure above red-line areas have been set with
matching O-Rings. Check below 7 parts are contained:
①Body②Nut Plate③Washer④Tube ⑤Pressure Nut
⑥Connector⑦Sleeve
Note:
The cable must be certified with EN/IEC.
Insert the cable into and through each part of Cable
Gland successively, as set forth in above picture. Use
watertight tape to twist round the screw part as red
circle of above picture.
Note:
It's recommended to twist round the screw part with 3-
circle.
Step 3
Step 4
Connect the Green-wire with the Ground-wire, connect
the White-wire with the Neutral-wire and connect the
Red-wire with the Live-wire by using the Closed-end-
terminal, then put the said wires in the connection
chamber of lighting fixture.
Note:
1. Pull the wires to ensure the Closed-end-terminal
are fixed.
2. Ensure the description of voltage on the cables fit
with the requirement of use.
Tighten the Cable Gland with the entry hole of cable of
lighting fixture by using a wrench.
Note:
1. Torque Range: 65N.m.
2. O-Ring used in the connection area of Cable Gland
and the lighting fixture, as red circle area on above
picture, should not be pressed and extended over
the outside diameter of Cable Gland.

Put the parts that are worn by the cable as described in
the Step 2 into the Cable Gland, then clockwise screw
the "Pressure Nut" with 60N.m torque range, as set
forth on above picture.
Note:
Please see the left picture to learn how to screw the
Pressure Nut.
Press the Nut Plate against the cable and use M4
screws to fix the Pressure Nut with cable. Use a M4
screw to fix the cable from the side face of the Pressure
Nut, as set forth on above left picture.
Note:
Make sure the M4 screws are completely tightened to
make the cable be fully fixed.
