2 System overview
2.1 General description
InteliMains-NT controller is comprehensive mains supervision controller for multiple generating sets
operating in parallel to the Mains. A modular construction allow upgrades to different levels of
complexity in order to provide the best solution for various customer applications.
NT Family controllers are equipped with a powerful graphic display showing icons, symbols and bar-
graphs for intuitive operation, which sets, together with high functionality, new standards in Gen-set
controls.
BaseBox versions of InteliMains controllers is now available. This version features controller without
built-in monochromatic display and can be combined with new and powerful display units InteliVision-8
and InteliVision-5. For more information on these products, please go to comap.cz web pages.
The controller automatically connects and synchronizes two parts of bus bar and controls the bus tie
circuit breaker (BTB).
The key feature of the controller is its easy-to-use operation and installation. Predefined configurations
for typical applications are available as well as user-defined configurations for special applications.
The key features are:
BTB controlled by InteliMains-NT
Highly customizable behavior of breaker control (dead bus, blockation of closing etc.)
Synchronization (voltage and phase matching) of two control groups separated by InteliMains-
BTB with various settings (which group synchronizes to which etc.)
Load shedding control (based on power transferred via BTB)
Full PLC logic included (useful in complex systems –BTB can for example serve as auxiliary
PLC for other controllers)
Support of redundancy controller
Full set of protections for BusL and additional protections for BusR
Group Link function
Active calls and SMS

3.1 IM-NT Installation instructions
This portion of Instalation instructions is dedicated to the
InteliMains-NT-GC controller with built-in display. If you have
BaseBox type of the controller (without the built-in display), please
refer to the section 3.2.
3.1.1 Mounting
Prepare the screw holders
Locate four sockets for screw holders
Insert the unit into cut-out in a switchboard and
insert all four screw holders accordingly to their
positions
Tighten as required to fix the controller in the
position

Pull down
Use boot jumper if controller is not responding to communication (e.g. due to faulty programming
sequence). Take off the rubber cover using screwdriver to acces boot jumper next to dongle slot.
Use 120 Ωterminators at the end of CAN1, CAN2 or RS485 buses. Do not use these terminators on
units that are not terminating the bus.
Use pull up and pull down resitors on RS485 to bias the line when no device is active on the bus to
prevent noise from undriven line to be interpreted as data.
3.2 IM-NT-BB and IM-NTC-BB Installation instructions
This portion of Instalation instructions is dedicated to the
InteliMains-NT-BaseBox and InteliMains-NTC-BaseBox
controllers without built-in display. If you have version with built-in
display of the controller, please refer to the section 3.1.

3.2.1 Mounting
BaseBox units are prepared for mounting on DIN rain mount (35mm).
Locate two plastic holders on the back side of the
controller
Make sure both holders are in open position (right
image). If not (left image) open them by pulling
them slightly out
Mount the unit on the DIN rail and secure by
pressing two plastic holder until they click and fix
the unit into position
BaseBox units may also be mounted on InteliVision 5 and together with it mounted into cut-out
in a switchboard.
Mount InteliVision 5 into the switchboard cut-out
(for more information on InteliVision 5 mounting
please refer to the InteliVision 5 Reference
Guide)
Use the rail provided on the back side of
InteliVision 5 and mount the controller to it while
following the same steps when mounting on
standard rail (rail openings on InteliVision 5 are
fixed so there is only one possible way how to
mount the controller to it)

terminator
Use boot jumper if controller is not responding to communication (e.g. due to faulty programming
sequence). Take off the rubber cover using screwdriver to acces boot jumper next to dongle slot.
Use 120 Ωterminators at the end of CAN1, CAN2 or RS485 buses. Do not use these terminators on
units that are not terminating the bus.
Use pull up and pull down resitors on RS485 to bias the line when no device is active on the bus to
prevent noise from undriven line to be interpreted as data.
3.3 Wiring (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
oSpecified tightening torque is 0,56Nm (5,0 In-lb)
oUse only diameter 2,0-0,5mm (12-26AWG) conductor, rated for 90°C
minimum.

For other controller field wiring terminals
oSpecified tightening torque 0,79Nm (7,0 In-lb)
oUse only diameter 2,0-0,5mm (12-26AWG) conductor, rated for
75°C minimum.
oUse copper conductors only.
3.4 Grounding (general)
The shortest possible piece of wire should be used for controller grounding. Use cable min. 2.5 mm2.
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
o1 amp for IM-NT
o2 amps for IM-NT-BB or IM-NTC-BB
Maximal continuous DC power supply voltage is 36VDC.
CAUTION!
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).
HINT
For more information on technical data regarding supply, inputs, outputs etc. please refer to
IGS-NT-Instalation Guide.
3.6 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.

3.7 Voltage and current inputs
WARNING!
Risk of personal injury due to electric shock when manipulating voltage terminals under voltage! Be
sure the terminals are not under voltage before touching them.
WARNING!
Do not open the secondary circuit of current transformers when the primary circuit is closed!!! Open
the primary circuit first!
Use 1.5 mm2cables for voltage connection and 2.5 mm2for current transformers connection.
Adjust nominal voltage, nominal current, CT ratio and PT ratio by appropriate setpoints in the Basic
Settings group.

CAUTION!
Check measurement connections carefully! Failure is possible if phases are connected in wrong order
(WrongPhSequence detected by the controller) but this is not detected if the phases are just rotated
(i.e. instead of phase sequence L1, L2, L3, phase sequence is e.g. L2, L3, L1.
