Mains connection and power supply
To achieve the full output, the resistance measured must not exceed the following values:
•
0.25 Ohm at 110 V (1-phase)
•
0.45 Ohm at 208 V
•
0.50 Ohm at 230 V
•
0.60 Ohm at 240 V
•
0.65 Ohm at 277 V
•
0.85 Ohm at 400 V (2-phase)
If the above values are exceeded, reduce the generator power in accordance with section
13 in this manual.
Checking the line voltage in the generator
1
If not already done, remove fuses F10 (1) and F20 (2) or, when single-phase supply,
fuse F10 (1).

2
Mains supply "ON".
3
Measure the voltage at fuse holders F10 (1) and F20 (2).
4
Check that the mains voltage agrees with the voltage plugged on transformer T10 (3)
and p.c. board D711 (4), located above line filter Z1 (5).
5
Mains supply "OFF".
6
Reinsert fuses F10 (1) and F20 (2).
