DANGER
Danger of death due to contact voltage!
Touching live parts will result in serious injuries or death!
Even when it is disconnected, high contact voltages can still occur in the
terminal box due to non-discharged capacitors. Therefore, work on the
terminal box module must not be started until 5 minutes have elapsed!
• Disconnect all poles of the supply voltage and secure against recon-
nection!
• Check whether all connections (including potential-free contacts) are
voltage-free!
• Never insert objects (e.g. nail, screwdriver, wire) into openings on the
terminal box!
• Reinstall removed safety devices (such as terminal box cover)!
DANGER
Danger of death from falling parts!
The pump itself and pump parts can have a very high net weight. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which can be
fatal.
• Always use suitable lifting accessories and secure parts against falling.
• Never stand below a suspended load.
• During storage and transport, as well as before all installation and as-
sembly work, ensure that the pump is in a safe position and standing
securely.
DANGER
Danger of death due to ejected tools!
The tools used during maintenance work on the motor shaft can be
thrown away if they come into contact with rotating parts. Injuries and
even death are possible!
• The tools used during maintenance work must be removed com-
pletely before the pump is started up!
WARNING
There is a risk of burns or freezing upon coming into contact
with the pump/system.
Depending on the pump and system operating conditions (fluid temper-
ature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• Allow the system and pump to cool down to room temperature!
• Always wear protective clothing, safety gloves and safety glasses
when working.
Before commissioning once maintenance work has been completed, see the "Commis-
sioning" chapter!
NOTICE
In the IPL-Z/DPL-Z version, the pump is fitted with a coupling guard that
can only be removed using a tool.
