• Position the threaded cable connection or lay the cables accordingly
to ensure that no drips can run into the terminal box.
• Non-assigned threaded cable connections must remain sealed with
the plugs provided by the manufacturer.
• When pumps are used in systems with water temperatures above
90 °C, a suitably heat-resistant power cable must be used.
• Fuse protection on mains side: Dependent on rated motor current.
NOTE
The connection diagram for electrical connections is in the cover of
the terminal box.
• For mains connection see also Fig. 3.
• The motor must be secured against overloading by a motor protection
switch.
• Earth the pump according to the regulations.
Alternating current, 1~230 V AC:
Connection cable, 3 x 0.75 mm
Alternating current, 3~230/400 V AC:
Connection cable, 4 x 0.75mm
DANGER! Risk of fatal injury!
Failure to install safety devices on the terminal box or near the
coupling can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
• Before commissioning and after maintenance work, all safety
devices (such as terminal box covers or coupling covers) that were
removed must be reinstalled.
• The tools used during maintenance work must be removed com-
pletely before the pump is started up.
• Keep a safe distance during commissioning!
WARNING! Risk of burns or freezing to the pump when body parts
come into contact with the pump!
Depending on the pump or system operating conditions (fluid tem-
perature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• In the case of high water temperatures and system pressures, allow
the pump to cool down before all work.
• Always wear protective clothing, protective gloves and protective
goggles when working.
WARNING! Danger of injury!
If the pump/system is installed improperly, liquid may be ejected
during commissioning. Individual components may also become
loose.
• Keep a safe distance from the pump during commissioning.
• Wear protective clothing and gloves.
WARNING! Danger of injury!
If contaminants make contact with the hot surfaces of the unit,
fires or explosions can result.
