Note "M": Remove link "M" when
parallelling with the mains. In
AMF-mode or in case of
mainsparallelling, the
Mains-sensing lines need to be
fused by the customer (3x
250mA). Fuse L1, L2 & L3 and
connect to X25.3, X25.4 & 25.5
When parallelling multiplegen-sets
in ISLAND-mode,link "M" is
necessary.
Note "P": Remove link "P" when
NOT running in ISLAND-mode.
Note: Connect R9 between
X32.1/X32.3 at the start and
between X32.4/X32.6 at the
end of data loop.
