WARNING
Luminaire must be earthed. Risk of electric shock from LED boards if operated with the cover removed. Installation/operation outside of luminaires’ intended scope invalidates the warranty. Suitable only for domestic/light industrial/industrial applications within the scope of EN55015. Tested to compliance with BSEN 60598: specification for general requirements and tests. Must be installed by a suitably qualified person in accordance with all relevant legislation. Ambient operating temperature of 0°C to 25°C. If the maximum operating temperature is exceeded luminaire will automatically dim/switch off. Terminal blocks are rated to 16A unless stated otherwise. The light source is nonreplaceable.
LUMINAIRES WITH EMERGENCY PACK
When the supply is isolated battery output terminals may be live if the battery is connected. Isolate mains and batteries before servicing. Emergency luminaires require an unswitched live connection taken from the same phase as switched supply. When an unswitched supply is connected status indicator illuminates green, when an unswitched supply is disconnected indicator extinguishes and the luminaire operates in emergency mode. 24-hour charge period is required before undertaking a full discharge test. Emergency test sheets provided should be used to record all emergency tests. Batteries should be replaced when the 3-hour duration is not met. Excessive switching of permanent life may result in premature battery failure. Battery electrolytes can be harmful to eyes / open wounds, do not puncture if electrolyte touches skin/eyes flush with water. Do not incinerate batteries.
