Table of internal fuse and external supply ratings.
The phases are generally unequal on these models. A figure equal to or exceeding the highest
phase current is shown, and the wiring and fusing should match or exceed this figure. The function
of the customer's (external) fuse is to protect the customer's wiring.

F1-F3: Refer to the circuit diagrams.
Fitted to all G range models.
For "universal" wiring each circuit has 2 fuses, in
most cases fitted on board to the EMC filter.
Fitted to all G range models.
In most cases fitted on board to the EMC filter.
Not fitted in standard G range models (wire size
does not reduce).
Required to protect customer supply circuit and
