Megging; Technical Data, Single-Phase Motors; Supply Voltage; Leakage Current - Grundfos TPE2 Notice D'installation Et De Fonctionnement

30. Megging

Megging of an installation incorporating MLE motors
is not allowed, as the built-in electronics may be
damaged.

31. Technical data, single-phase motors

31.1 Supply voltage

• 1 x 200-240 V - 10 %/+ 10 %, 60 Hz, PE.
Confirm that the supply voltage and frequency correspond to the
values stated on the nameplate.
Recommended fuse size
Motor size
[hp (kW)]
0.33 - 1.0 (0.25 - 0.75)
1.5 - 2.0 (1.1 - 1.5)
You can use standard as well as quick-blow or slow-blow fuses.

31.2 Leakage current

Ground leakage current less than 3.5 mA, AC.
Ground leakage current less than 10 mA, DC.
The leakage currents are measured in accordance with
EN 61800-5-1:2007.

32. Technical data, three-phase motors

32.1 Supply voltage
• 3 x 440-480 V - 10 %/+ 10 %, 60 Hz, PE.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
Recommended fuse size
Motor size
[hp (kW)]
0.33 - 1.5 (0.25 - 1.1)
2.0 (1.5)
3.0 (2.2)
You can use standard as well as quick-blow or slow-blow fuses.
• 3 x 200-240 V - 10 %/+ 10 %, 60 Hz, PE
