8. Measurement and Power
Supply Wiring
8.1. General
To ensure proper function:
•
Use grounding terminals.
•
Wiring for binary inputs and analog inputs must not be run with power cables.
•
Analog and binary inputs should use shielded cables, especially when the length is
more than 3 m.
Tightening torque, allowable wire size and type, for the Field-Wiring Terminals:
•
For Mains(Bus) Voltage, Generator Voltage a Current terminals
o
Specified tightening torque is 0,56Nm (5,0 In-lb)
o
Use only diameter 2,0-0,5mm (12-26AWG) conductor, rated for 90°C
minimum.
•
For other controller field wiring terminals
o
Specified tightening torque 0,79Nm (7,0 In-lb)
o
Use only diameter 2,0-0,5mm (12-26AWG) conductor, rated for
75°C minimum.
o
Use copper conductors only.
8.2. Grounding
The shortest possible piece of wire should be used for controller grounding. Use cable min.
2.5 mm
2
. A brass M4x10 screw with star washer securing ring type grounding terminal shall
be used.
The negative “-” battery terminal must be properly grounded.
Switchboard and engine must be grounded at a common point. Use as short a cable
as possible to the grounding point.
8.3. Power supply
To ensure proper function:
•
Use power supply cable min. 2,5mm
2
•
Use fuse
o
1 amp for IM-NT
o
2 amps for IM-NT-BB or IM-NTC-BB
•
Maximal continuous DC power supply voltage is 36VDC.
