Measure the voltage (RMS)
between phase and neutral.
Connect the voltmeter to the
terminals at the connection.
The voltage should, when the motor is
loaded, be within the range specified in sec-
tion 6. Electrical connection.
Large variations in supply voltage indicate
poor electricity supply, and the booster
module should be stopped until the defect
has been remedied.
2. Current consumption

Measure the current (RMS)
while the pump is operating at
a constant discharge head (if
possible, at the capacity where
the motor is most heavily
loaded).
For maximum current, see
nameplate.
If the current exceeds the full load current,
there are the following possible faults:
• Poor connection in leads, possibly in the
cable joint.
• Too low supply voltage, see item 1.

When the booster module is taken out of
operation, it must be ensured that no haz-
ardous material is left in the module, which
can be injurious to persons and the envi-
ronment.
Subject to alterations.
