Outside the light fitting appropriate measures (e.g. pull relief clips) must be taken to
!
protect the connection cable from twist and it must be ensured that no tensile forces react
on the wiring and the Ex cable gland!
The diameter of the connection cable must correspond to the sealing range of the Ex
cable gland (see section 3, Technical Data)!
The conductors must not be damaged when skinning resp. stripping the cable!
When stripping the cable special attention needs to be paid to the correct length of the
conductor end sections (see section 3, Technical Data)!
Connect the conductors of the connection cable to the right terminals as per marking.
It is important to ensure that the bare conductor is fully inserted into the terminal and that
no cable insulation is clamped!

4.3 Replacing LED circuit boards and electronic gear
Replacement of the LED boards and/or of the electronic gear has been described in the separate
instructions which can be found attached to the spare parts to be supplied.
4.4 How to close the light fitting
Put the parts of the housing together and tighten the two screws in the front part of the housing.
The two screws must be tightened so far that the two housing parts are firmly on top of one another

5. Commissioning
Before commissioning this explosion-proof lighting fitting please check and ensure that:
the light fitting has been installed according to the regulations and in the allowed operating position.
the Ex cable glands are securely fixed in the housing and the closing plug is installed in a proper
manner (Torques see section 3, Technical Data).
the pressing screw of every Ex cable gland is tightened with the required torque (Torques see
section 3, Technical Data).
the connection cable has been firmly installed and is not subject to any tension whatsoever.
the bare conductor is fully inserted into the terminal and that no cable insulation is clamped.
the light fitting is closed correctly.
all gaskets are effective.
the light fitting is not damaged whatsoever.
The restricted breathing of the light fitting is condition for its safe operation!
Therefore, prior to commissioning, check the restricted breathing in accordance with
!
