DANGER Risk of fire  /risk of explosion due to short circuit and escaping oxyhydrogen gas. Risk of (burn) injury caused by caustic burns to eyes, skin and mucous membranes from battery electrolyte/mist, short circuit and arcing. Risk of poisoning  caused by swallowing battery electrolyte or absorption of lead through the skin or body orifices. Risk of death  due to voltage U >= 30 V AC and U >= 60 V DC. No fires, sparks, open flames, or smoking. Wear acid-resistant gloves, clothing, and glasses. Pour battery acid only into suitable and appropriately marked containers. AS54.10-Z-0001-01A

2 Check hazard potential of on-board electrical system battery (2). When replacing the on-board electrical system battery (2).  
    IMPORTANT In the event of smoke generation or fire, the fire department must be notified. AR47.70-P-0017-01A
    IMPORTANT The analysis sheet must be used to check whether the on-board electrical system battery (2) presents an acute hazard.  
3 Check housing of on-board electrical system battery (2) for mechanical damage. IMPORTANT The analysis sheet must be used to check whether there is damage to the on-board electrical system battery (2) causing electrolyte to leak out.
If there is an electrolyte leakage,

notify MPC/general representative.

5 Set switch (3) to position "1". IMPORTANT The "POWER" lamp must light up.  
6 Check flash code of "TEST" lamp. IMPORTANT The "TEST" lamp flashes (1 s ON, 1 s OFF): on-board electrical system battery (2) is safe for transportation.  
    IMPORTANT The "TEST" lamp flashes (0.1 s ON, 1 s OFF): on-board electrical system battery (2) is not safe for transportation.  
    If the on-board electrical system battery (2) is not safe for transportation,

set switch (3) to position "0", disconnect test box (1) and repeat test after 70 min.
 
    If the on-board electrical system battery (2) is not safe for transportation,

contact responsible MPC/general distributor.
 
7 Set switch (3) to position "0".    
8 Disconnect test box (1).
