Description
20
MPU +
Analog input, 0.5 to
30V-AC
Connect one terminal of the MPU unit to
this input. Use a twisted cable pair or
coaxial cable for best results.
21
MPU - / PROTECTION
GROUND
Output 0Vdc
Connect one terminal of the MPU unit to
this input. Use a twisted cable pair or
coaxial cable for best results.
Connect the protective shield of the
CANBUS cable to this terminal.
22
CANBUS-H
Digital communication
port
Connect the J1939 port of an electronic
engine to these terminals.
The 120 ohm terminating resistors are
inside the unit. Please do not connect
external resistors.
Use a twisted cable pair or coaxial cable
for best results.

Description
51
GENERATOR CONTACTOR
Relay output, 16A-AC This output provides energy to the
generator contactor. If the generator
phases do not have acceptable voltage or
frequency values, the generator contactor
will be de-energized. In order to provide
extra security, the normally closed contact
of the mains contactor should be serially
connected to this output.
52
GEN-L1
Generator phase
inputs, 0-300V-AC
Connect the generator phases to these
inputs. The generator phase voltages
upper and lower limits are programmable.
54
GEN-L2
56
GEN-L3
58
GENERATOR NEUTRAL
Input, 0-300V-AC
Neutral terminal for the generator phases.

Description
59
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).
