Cleaning and Maintenance
Keep non-expert persons away during maintenance and
repair work and place warning signs or barriers around the
operating area, as well as warning signs on all switches.
Do not operate the system until it has been fully reinstalled
and put back into service.
Important safety instructions for qualified personnel
for maintenance and repair
After the appliance has been taken out of service,
observe the following instructions:
• For any maintenance and repair work, the relevant safety
standards and specifications must be observed!
• Always make sure that no one can be injured!
• Ensure a dry and clean working environment.
• Use suitable protective equipment, such as insulated gloves
and shoes, and noise protection for the ears
while working on the system.
• Disconnect all electrical connections from the system.
• After disconnecting, wait at least 5 minutes until the
residual voltage of the capacitors has dropped to a safe level.
Use a multimeter to ensure that all components are
fully discharged.
• In the event of a deep discharge, the battery storage must be
recharged to a SOC of 30% to 50% if the entire system is static
(i.e. if the battery storage has not been charged for 2 weeks or
more).
• If circumstances or questions arise that are not explained
in this manual, contact customer service.
