Installation and operating instructions Wilo-VeroLine-IPH-O, IPH-W
• The use of a motor protection switch is recommended.
Setting the motor protection switch:
• Direct starting:
Set according to the rated motor current specified on the name
plate of the motor.
• Y-Δ start:
If the motor protection switch is switched in the supply line to
a Y-Δ contactor combination, set the switch as for direct starting.
If the motor protection switch is switched in a thread of the motor
supply line (U1/V1/W1 or U2/V2/W2), set the motor protection
switch to 0.58 x rated motor current.
• The mains connection to the terminal board is dependent on the
motor power P , the mains voltage and the start-up type. The recom-
2
mended switching arrangement of the connection bridges in the ter-
minal box should be taken from the following table and fig. 8.
• When connecting automatic switching devices, observe the relevant
installation and operating instructions.

DANGER! Risk of fatal injury!
Failure to install safety devices on the motor, terminal box or on
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.
• Keep a safe distance during commissioning.
• Always wear protective clothing, protective gloves and protective
goggles when working.
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.
NOTE
Depending on the pump's installation position, one of the venting
screws is not necessarily at the highest point (fig. 1, Item 441h and
fig. 2). In this case, you have to loosen the socket screws on the pump
housing and rotate the "lantern and motor" unit so that one of the
venting screws is at the highest point.
CAUTION! Risk of damaging the pump!
• When rotating the "lantern and motor" unit, take care not to
damage the housing's flat gasket.
CAUTION! Risk of damaging the pump!
• Protect the terminal box from any water escaping when venting.
• Close the stop valve on the pressure side.
