5 Installation & Wiring
● Installation and wiring must be performed by a specialist in accordance with IEC 60079-14.
● For safety reasons, the installation of this product must be performed by two or more persons.
● Make sure to turn off the power supply during the installation.
● When opening and closing the main unit cover, be careful not to damage the joint surfaces of the main unit cover
and bracket.
● Make sure to choose the correct voltage when wiring inside of the bracket.
● Do not apply voltage to the flashing common line (
the power line (
● Do not flash the light by turning the power ON and OFF repeatedly for (
● For wiring work, the appropriate size of the explosion-proof cable gland is NPT 3/4. Make sure the threaded
Caution connection is properly sealed to prevent water penetration.
● Use the explosion-proof cable gland available from our optional parts (certified products). Explosion-proof cable
glands other than our optional parts cannot be used, as this is a requirement of the explosion-proof certification.
● When wiring the terminal block, do not apply excessive force. This may result in damage, deformation and
potential failure.
● To prevent twisting or disconnecting earthing connection facility, the earthing wire should be secured to fixed part.
● The stranded wire is suitable for connecting 0.75 to 2.5 mm² conductor.
● For the internal earthing connection facility, according to the size of the stranded wire used, the same conductor
size shall be selected and used from 0.75 to 2.5 mm².
● The external earthing connection facility is suitable for connecting 4 mm² wiring.
● About shat bolt between body cover and bracket, see specific condition of use.
■ Installation
1. Drill the mounting holes (refer to the mounting dimensions shown in "4. Part Names & Dimensions ") at the installation site.
2. Secure and fix the main unit at 4 points with M8 bolts and nuts. (Recommended tightening torque: 12.3 N m)
(M8 bolts and nuts are not included.)
■ Wiring
1. Remove the 8 hexagon socket head cap screws (M10 X 27) with the supplied hex wrench and open the space between the main unit cover
and the bracket. The main unit cover and bracket are connected by a hinge. Do not remove the hinge.
2. When connecting wires to terminal block (refer to P3. Terminal Block Wiring Procedure), make sure the polarity is correct.
3. Connect the ground wire to the external ground terminal or the ground terminal of the terminal block.
For connection to external ground terminal
For connection to the ground terminal of terminal block : Use wires between 0.75 mm
※For further specifications on wiring, refer to "Terminal Block Wiring Procedure".
4. Close the main unit cover and secure the unit firmly by tightening the 8 hex socket head cap screws (M10 X 27) using the supplied hexagonal
wrench. (Recommended tightening torque: 24.4 N m)
When doing so, be careful not to pinch the wires. Also, do not remove the O-ring (rubber gasket) that comes with the main unit cover.
