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.
3.4
Grounding (general)
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.
3.5
Power supply (general)
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.
C
AUTION
!
Switchboard lightning strikes protection according standard regulation is expected!!!
The maximum allowable current through the controller negative terminal is 3 to 8A (depends on the
controller type and binary output load).

Power supply fusing (general)
Always use according fuse (1Amp or 2Amps) when
connection controller, extension modules or relays to
a power source.
See the diagram for proper fusing.
