Megging; Checking Of Motor And Cable; Environment; Disposal - Grundfos SQE Montage- Und Betriebsanleitung

9.1 Megging

Megging of an installation incorporating SQ/SQE
pumps is not allowed, as the built-in electronics may
be damaged, see fig. 13.

11. Environment

During handling, operation, storage and transport, all
environment regulations dealing with the handling of
hazardous materials must be observed.
When the pump is taken out of operation, it
must be ensured that no hazardous mate-
rial is left in the pump/motor and the riser
pipe, which can be injurious to persons
and the environment.
In case of doubt, please contact GRUNDFOS or the
local authorities.

Measure the voltage (RMS)
between phase and neutral.
Connect the voltmeter to the
terminals at the connection.
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.

12. Disposal

Disposal of this product or parts of it must be carried
out according to the following guidelines:
1. Use the local public or private waste collection
service.
2. In case such waste collection service does not
exist or cannot handle the materials used in the
product, please deliver the product or any haz-
ardous materials from it to your nearest GRUND-
FOS company or service workshop.
The voltage should, when the motor is
loaded, be within the range specified in sec-
tion 4. Electrical connection .
Large variations in supply voltage indicate
poor electricity supply, and the pump should
be stopped until the defect has been reme-
died.
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.
Subject to alterations.
