Notes
Note 1: The PE-N connection has to be made at the
alternator-side of main Circuit Breaker Q1.
Note 2: Link N12.1 to N12.2 on gen-sets without Dual Frequency
(= no potentiometer R12).
Note 3: With "TB EDF", do NOT connect (N) to (PE) at Q1.
T13 is to be mounted on the (PE)-conductor, in
stead of on the PE-N connection in the cubicle.
