WARNING!
-- Danger of life through electrical voltage!
!
Prior to any maintenance work -- unless described otherwise -- the system must
always be switched off! If the system had been active shortly before, wait until
the system is totally de--energized before starting the maintenance work (e.g.
beause of charged capacitors, etc.). For the duration of the maintenance work
the system must always be protected against re--closing.
In the event of necessary measurement or test procedures at the active system,
the applicable safety and accident prevention regulations must be strictly ob-
served. In any case, suitable insulated tools must be used!
-- Danger of life through electrical voltage!
If the inverter housing is to be opened, switch off the system and wait for at least
5 minutes for the inverter to de--energize.
-- Danger of life through inappropriate EMERGENCY--OFF facilities!
EMERGENCY--OFF facilities must be operative in all modes of the system. Re-
leasing the EMERGENCY--OFF facility must by no means result in an uncon-
trolled restart of the system!

Batteries must not be opened forcefully, recharged, soldered at the cell body or
thrown into fire!
Replace empty batteries with new ones only!
