manner, following the recommended operating procedures in this manual.
Battery voltage higher than 400Vdc
All the battery maintenance and servicing procedures involving internal access need special tools or keys and should be
carried out only by trained personnel.
SPECIAL CARE SHOULD BE TAKEN WHEN WORKING WITH THE BATTERIES ASSOCIATED WITH THIS EQUIPMENT.
WHEN CONNECTED TOGETHER, THE BATTERY TERMINAL VOLTAGE WILL EXCEED 400Vdc AND IS POTENTIALLY
LEATHAL.
