LED-reflector with mounted LED-modules and Electronic control gear of this light fitting must be replaced by A. Schuch GmbH, by a service technician who is instructed from Schuch or by any other person with equivalent qualification only. It is not allowed to replace the individual LED-modules of this light fitting. -

Against penetration of humidity into the light fitting a special explosion-proof breathing gland is often quite effective. It is allowed to use a breathing gland which is released by the Adolf Schuch GmbH only. If using a breathing gland please observe the general informations of it's operation instructions. - Page 4 2.1 Use at high and low temperatures The explosion protection of the light fitting is guaranteed between -30°C up to +40°C/+55°C. At temperatures below 0 °C, it must be taken into account that the emergency battery will take longer to charge and the operational life of the emergency lighting mode will be reduced. Testing the duration of the battery life in lower ambient temperatures can therefore lead to a misleading result.
- Page 5 Under the above mentioned preconditions, after a correctly performed switching sequence at L1' terminal, an operational life test is immediately initiated. If the switching sequence is correctly carried out on L1 terminal, an operational life test is initiated after the time that is required to fully charge the battery after the switching sequence. If the switch sequence has not been carried out correctly, or the aforementioned requirements have not been satisfied, the operational life test will not be conducted.
- Page 6 2.4 LED-Signals The two-colored LED (red/green) which is integrated in the reflector of the light fitting does show the working condition and the error state of the fitting. The following states are possible: Permanent charging mode – Continuous green light: light fitting at mains operation, the emergency battery is being charged Blinking green light:...

Page 9: Installation
4. Installation The safety of this light fitting is only guaranteed as long as it is operated within its assessment threshold. Installation and maintenance must be done in accordance with the respective regulations! The installation of explosion-proof light fittings must be done by Ex-skilled electricians only! ... - Page 10 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.
- Page 11 5. Commissioning If a power supply is present, the battery connected to the emergency light unit will be charged. The signal LED will indicate this state by means of a steady green light. After the initial setup, the emergency battery must be charged for 12 hours. From a physical point of view, the full capacity of the battery is only available after 3 or 4 charge- discharge cycles.
- Page 12 5.2 Emergency light unit in 3-phase-operation The diagram shows the wiring for light fittings or light fitting groups in 3-phase circuits and with a common neutral conductor N. Light fittings with emergency light unit fault If the common neutral conductor is interrupted and voltage is present, then light fittings or groups of light fittings may be exposed to unacceptably high voltages and consequently the emergency light unit may be destroyed.

For applications in dusty atmospheres the light fitting must be cleaned before opening! Ensure that no dust can get into the light fitting when it is open! Replace damaged explosion-proof parts by original spare parts from the Adolf Schuch GmbH only! ... - Page 14 6.4 How to replace the emergency battery Follow the instructions of section 6.1! Only original batteries as per the type plate on the battery must be used for replacing the battery (see Chapter 3, Technical Data)! Version without battery box: ...
- Page 15 Alert the emergency light unit to the presence of a new battery: Open and close the lid of the battery box twice within a 60-second period. Opening and closing the case must occur within 10 seconds of each other. If this procedure is done correctly, immediately after the battery box is closed for the second time, the signal LED will display an acknowledgement light.
