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. 

 

If a battery contact failure is indicated despite an existing connection to a power supply and to the 
emergency battery, the emergency battery may be the cause, which might contain insufficient charge 
to be charged in the potentially explosive atmosphere. 
In this case, the emergency battery is to be removed as described in Section 6.3 and to be charged 
separately from the light fitting. With a 6 V charging voltage and 80 mA charging current, a discharged 
battery will be sufficiently charged within just 5 minutes for it to be reinserted into the light fitting, where 
it can continue to charge.  

 

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 explosion-proof cable glands resp. explosion-proof locking screws are securely fixed in the 

housing (Torques see Chapter 3, Technical Data). 

 the pressing screw of every explosion-proof cable gland is tightened with the required torque 

(Torques see Chapter 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. 

 

5.1  Isolation measurement 

 

For measuring the isolating resistance the test voltage must be put on between the outer conductor 
and the  
earth conductor or between the neutral conductor and the earth conductor only. 
 
 
 
 
 
 
 
 
 
 
After finishing the isolation test the conductor between the mains and the light fitting must be 
reconnected safely. Before starting operation the connection of the neutral conductor must be safe for 
avoiding any damage whatsoever of the electronic control gear caused by any inadmissible excess-
voltage in case of an unbalanced mains load. (see Chapter 5.2)
