21. Megging
Do not meg an installation incorporating MGE
motors, as the built-in electronics may be damaged.
22. Technical data, single-phase
motors
22.1 Supply voltage
Single-phase motors are available for the voltages
below:
• 1 x 200-240 V - 10 %/+ 10 %, 50/60 Hz, PE
• 1 x 90-240 V - 10 %/+ 10 %, 50/60 Hz, PE or
30-300 VDC (power supply from a
renewable-energy source).
Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
Recommended fuse size
You can use standard as well as quick-blow or
slow-blow fuses.
22.2 Leakage current
Earth leakage current less than 3.5 mA (AC).
Earth leakage current less than 10 mA (DC).
The leakage currents are measured in accordance
with EN 61800-5-1:2007.
23. Technical data, three-phase
motors
23.1 Supply voltage
• 3 x 380-500 V - 10 %/+ 10 %, 50/60 Hz, PE.
Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
Recommended fuse size
You can use standard as well as quick-blow or
slow-blow fuses.
23.2 Leakage current (AC)
The leakage currents are measured without any load
on the shaft and in accordance with EN
61800-5-1:2007.
