2. Important safety informaon
WARNING: ELECTRIC SHOCK
Failure to obey the informaon that follows this Warning could result in injury or
death by electric shock. Read and obey this safety informaon.
▪The electrical installaon must be done by a suciently qualied person. Obey
the naonal regulaons in the country of use (for example, EN 50110-1 for
Europe).
▪Lethal voltages are present at the mains connecons. Before you start
maintenance and service work, de-energise (lockout/tagout) the product rst.
▪Unplug any connectors only when the mains voltage is switched o and the pump
does no longer turn.
▪At speeds below 200 Hz, there is not enough power for the LEDs. The pump can
connue to operate without LED indicaon.
▪Unauthorized device conversion and modicaons are prohibited for safety
reasons.
▪Hazardous voltages are present within the converter. Contact with the converter
can cause death or injury. Aer the pump has stopped, disconnect the converter
from the mains power. Make sure that the pump cannot be accidentally switched
on (lockout/tagout) before you open it. There are no user serviceable parts in the
converter.
▪Put connecng lines so that they cannot be damaged. Protect the lines against
humidity and contact with water. Prevent any heat stress on the line due to
unfavourable condions.
▪ Support the connecng lines so that the pumps are not exposed to major
mechanical stress.
▪ Do not expose the converter and the connecons to dripping water. Read the
informaon on the IP type of protecon.
▪ When converter and connecng lines are stored in a humid atmosphere, they can
suer corrosion. Corrosion can cause conducve deposits which can cause short-
circuits and reduce the insulaon levels of electrical components
▪Transport the converter and connecng cables in their original packaging to avoid
mechanical damage. This can prevent air gaps and creepage distances.
▪Do not make electrical connecons unl the pump and accessories (e.g. air
cooler) have been installed mechanically.
