2.5 Instructions for special versions with remote cutoff switch
Special versions of these lighting fixtures are equipped to be connected to a remote cutoff switch.
Through a remote cutoff switch (isolated switching contact) it is possible to remove the light fitting from
operation, e.g. during maintenance.
The remote cutoff switch must be closed during normal operation of the special light fitting.
If the remote switch is open, there will be no emergency lighting in the case of a power outage.
A change to the switch position of the remote cutoff switch is only indicated if the fixture is connected
to a power supply.
 If no power supply is present, when the remote switch is closed (resetting the
deactivation) the light fitting will not enter emergency lighting mode!
!
Functionality and operational life tests that are due to be carried out when the remote cutoff switch is
deactivated will be postponed until the deactivation is reset, and will be conducted when the necessary
requirements for the respective test are satisfied.
The interval of functionality and operational life tests are not affected by deactivating the light fitting.
