1.General Description
The n-DNet™ MiniHub is a standalone network interface unit connecting endpoints to the Mobix
patented n-Dimensional Network (see box for n-DNet™ description) t is a feature rich MiniHub
designed to collect, store and forward data from up to 2 meters. Meters could be in any combination
of electric, gas and/or water with Pulse, RS-232 or RS-485. As a node on the patented n-Dimensional
mesh network, the n-DNet™ MiniHub communicates simultaneously in parallel over RF and PLC
there by guaranteeing continuous reliable two-way communications at the highest cost efficiency.
System tempering detection, parameter driven abnormal consumption and remote service connect/
disconnect are among the smart n-DNet™ MiniHub unique features.

1.Installation
1.There are 2 options to mount the MiniHub:
•Mount on a D N rail using the dedicated D N mounting on the back of the box.
•Using the mounting holes on the back of the box
See appendix 2
2.To prevent fire spreading in case of circuit faults, the Hub must be installed in a suitable fire
enclosure to the latest version of UL 61010-1, without any openings at the bottom.
3.Connect the 8 control wires to the bottom pitches according to the pin numbers. Use the
designated screws.
This is a view of the wire connections of the MiniHub:

4.According to the scheme of connection:
•Meter pulse wires ( N_1, N_2,GND)
The number indicates the meter’s number
Each two meters have a joint ground connection
Connect the (+) wire to the numbered input
Connect the (-) wires to the joint GND connector
1.Meter Pulse + Valve control (GND, N_2, N_1,Out_2,Out_1)
The output number indicates the controlled valve.
Out_2 – Connect the (+) wire of the valve control to the numbered output.
Out_1 – Connect the (-) wire of the valve control to the numbered output.
N_2 – Connect the alarm wire of the Meter to the numbered input
N_1 – Connect the (+) wire of the Meter to the numbered input
GND – Connect the ground wire of the Meter.
1.RS-485 or RS-232 Meter (Tx,Rx) plus 220v Valve control.
2.Connect the power supply cable to a 230/110Vac power source.

4.Safety
•Connect the input and output wires only when mains are not connected
•To prevent fire spreading in case of shortcut, the hub must be installed in a suitable enclosure
without any openings at the bottom.
•Connect mains only to 110-230Vac power source
•All AC connections should be done by an authorized electrician
•The unit intends to be powered from building wiring in Overvoltage Category . f the unit is
installed in Overvoltage Category higher than , external overvoltage protective device compliant
with EC 61643 standard and NEC/CEC shall beprovided in building installation to reduce mains
transients to Overvoltage Category .
1.Supply disconnect switch
A supply disconnect switch, or a circuit breaker must be installed at the connection point of the
power cable to the mains. Circuit breaker should be a standard device with the following
characteristics - 2A 110/230VAC 50/60Hz. An example - S201M-C4NA by ABB. The switch should be
in close proximity to the hub within easy reach for the operator. A marking should be added on the
switch identifying it as a disconnection device for the hub.
5.Environmental characteristics
•The Hub is intended for indoor use only. For outdoor application a weatherproof external enclosure
should be added.
•nstallation site altitude will be up to 2000m.
•Temperature range should be -40- +70 deg C. For harsher temperatures an external temperature
controlled enclosure should be added.
•Maximum relative humidity 80% for temperatures up to 31 deg C decreasing linearly to 50%
relative humidity at 40 deg C.
•Mains supply voltage fluctuations up to +-10% of the nominal voltage.
•Overvoltage category
•Pollution Degree 2
