3 - DESCRIPTION & CONNECTION TO THE ELECTRICAL SYSTEM
NanoVIP
3
is designed to carry out both real time
measurements and extended measurement campaigns.
It is equipped with shockproof, anti-slip rubber details which
make it easy to hold with one or both hands, and a support
which allows the user to place the instrument on a level
surface.
NanoVIP
3
has to be connected to the electrical system by
means of special voltage and current inputs.
The figure below shows the 3 voltage channels
U1
,
U2
and
U3
, with common neutral (
N
), and the 4 independent current
channels
I1
,
I2
,
I3
,
In
.
The initials below the inputs help the user identify them.
The voltage cables - which come with the instrument - are connected to the voltage inputs. Make sure the
cables are connected to the corresponding colours. Alternatively, any cable with a blade plug connector,
∅
4mm
and certified for at least 600V CAT III, may be connected.
The current inputs can be connected to the flexible current mini-clamps, which come with the instrument and
are marked with special coloured rings, which correspond to the different phases. Alternatively, other Elcontrol
Energy Net amperometric probes may be
used, depending on the specific measurement
requirements.
For more details, read Sect. 9 – Accessories &
Spare Parts.
An independent, auxiliary voltage input
(
U
AUX
) and an independent, auxiliary current
input (
I
AUX
) are also available.
The cables and current sensor for such
channels are optional (see Sect.
"ACCESSORIES").
3.1 - Power Supply
NanoVIP
3
is equipped with an external power supply which can be connected to any socket (USA/JP, UK, EU,
AU) with voltage 100÷240V~ ±10% and frequency 47÷63 Hz.
The output jack of the power supply is to be connected to the special 7.5VDC connector of the device.
The instrument is also equipped with a NiMh rechargeable battery pack, which guarantees more than 24 hours
of use, without you having to connect it to the main line. Batteries are recharged by an external power supply,
which is supplied with the instrument. Batteries cannot be recharged through the USB connection.
If NanoVIP
3
is not used for a long period of time, then perform a charge cycle every two months
(approximately) to prevent the batteries from going almost completely flat, in which case you will no longer be
able to recharge them.
