4.2 Electrical connection
Screw the explosion-proof cable glands and explosion-proof locking screw supplied with the fitting
into the borings of the housing by using the lock nuts (Torques see Chapter 3, Technical Data).
After mounting the light fitting housing insert the connection cable through the explosion-proof cable
gland. An inlaid dust protective disc, if existing, must be removed before.
Fasten the pressing screw of the explosion-proof cable gland (Torque see Chapter 3, Technical
Data).
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 cable entry!
The diameter of the connection cable must correspond to the sealing range of the
explosion-proof cable gland (see Chapter 3, Technical Data)!
Cable entries, which are not used, must be closed with the enclosed closure plug
(Torque see Chapter 3, Technical Data)! An inlaid dust protective disc, if existing, must
be removed before.
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 Chapter 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!
Modes of operation
Stand-by operation:
The light fitting switches on automatically in case of a mains failure.
Only the direct phase (L1) will be connected to connecting point L1 as mains supply monitor.
Maintained operation:
The light fitting switches on automatically and it may be used as a standard light fitting if mains voltage
is on.
The same direct phase (L1) will be connected to connecting point L1 as mains supply monitor and to
connecting point L1' as switched phase.
