Current
transformer
inputs, 5A-AC
Connect the generator current transformer
terminals to these inputs.
Do not connect the same current
transformer to other instruments otherwise
a unit fault will occur.
Connect each terminal of the transformer
to the unit’s related terminal.
Do not use common terminals. Do not use
grounding.
Correct polarity of connection is vital.
The rating of the transformers should be
identical for each of the 3 phases.
The secondary winding rating shall be 5
Amperes. (ex: 200/5 Amps).

MAINS-L3
Mains phase inputs,
0-300V-AC
Connect the mains phases to these inputs.
The mains voltages upper and lower limits
are programmable.

MAINS CONTACTOR
Relay output, 16A-AC
This output provides energy to the mains
contactor. If the mains phases do not have
acceptable voltages, the mains contactor
will be de-energized. In order to provide
extra security, the normally closed contact
of the generator contactor should be
serially connected to this output.
