Carbolite GVC Series - Manual (Page 6)

G range
6 MF48 -1.18
Models -/600 to -/1200 (and -/450 3-phase)
These models are all made to a “universal” wiring scheme, whereby the customer may, if
necessary, convert between single- and 3-phase supplies of the following types:
- 200 to 240V single-phase
- 200 to 240V 3-phase without neutral (delta)
- 380/220 to 415/240V 3-phase with neutral
To reconfigure the wiring to change between types of supply, see section 7.7.
To check the setting for the voltage within the range, or to alter it, follow the instructions in
section 8.2.
Special Voltages
The furnaces can be specially made to suit certain special voltages, such as 440/254 or 480/277.
Because of unbalanced phases the furnaces cannot be made to suit 3-phase without neutral of
380V or above.
At the time or writing, 110-120V models are not available.
Furnaces made for special voltages are generally not convertible between configurations and
voltages.
