27. Technical data, single-phase motors
27.1 Supply voltage
• 1 x 200-240 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
Standard as well as quick-blow or slow-blow fuses may be used.
27.2 Leakage current
Earth leakage current less than 3.5 mA (AC supply).
Earth leakage current less than 10 mA (DC supply).
The leakage currents are measured in accordance with EN
61800-5-1:2007.
28. Technical data, three-phase motors
28.1 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
Standard as well as quick-blow or slow-blow fuses may be used.
28.2 Leakage current
The leakage currents are measured in accordance with EN
61800-5-1:2007.
29. Inputs or outputs
