Maintenance

The inverter is basically maintenance-free. Despite this, it is a good idea to regularly check that the
cooling fins on the front and rear sides of the device are free of dust.
Clean the inverter when necessary as described below.
Attention
Danger of damage to components.
• Do not allow cleaning agents and devices to penetrate between the cooling fins at the front of
the inverter(under the hood).
• Do not use especially the following cleaning agents:
– Solvent-based cleaning agents
– Disinfection agents
– Coarse or sharp-edged cleaning agents
Removing dust
 Dust should be removed using compressed air (max. 2 bar).
Removing heavy soiling
Danger
Risk of death by electrocution! Use cleaning agents only with a slightly damp cloth.
 Remove heavy soiling with a slightly damp cloth (use clear water). If necessary, use a 2% hard
soap solution instead of water.
After cleaning, remove any soap residue using a slightly damp cloth.
