‧ We recommend protecting all electrical aquarium appliances via a residual current
protective device with a rated residual current of 30 mA maximum.
‧ If they are not being used, always disconnect all devices in the aquarium from
the power supply before you install/remove any parts and before all cleaning and
maintenance work.
‧ Protect the mains socket and power supply unit against
moisture and wetness. A drip loop must be formed with the
cable of the power supply unit. This prevents any water
running along the cable to the mains socket, which would
result in a short-circuit.
‧ The electrical data of the power supply unit must match
the data of the power mains. This data is found on the type
plate, the packaging and in these instructions.
‧ This appliance is operated without an earth connection.
‧ Only use the power supply unit that has been supplied with the appliance. If it
needs to be replaced, then an original EHEIM power supply unit has to be used.
