1 APPLICATION
The ND30 meter s a programmable d g tal nstrument des gned for the
measurement of 1-phase 2-w re and 3-phase 3 and 4-w re power network
parameters n balanced or unbalanced systems. The measured values are
d splayed on a 3,5’’ TFT full-color screen, resolut on: 320 x 240 p xel.
The meter enables control and opt m zat on of the power electron c dev ces,
systems and ndustr al nstallat ons.
The meter prov des measurement of: RMS of voltage and current, act ve,
react ve and apparent power, act ve, react ve and apparent energy, power
factors, frequency, the harmon cs of current and voltage /up to 51st/, THD of
voltage and current, averaged act ve and apparent power P Demand,
S Demand, averaged current I Demand /15, 30 or 60 m nutes/. Voltages and
currents are mult pl ed by g ven voltage and current rat os of the measur ng
transformers. Power and energy nd cat ons take nto account all
programmed rat o values. The value of each measured value can be
transm tted to the master system v a the RS-485 or Ethernet nterface.
Three relay outputs s gnal the overflow of the chosen value and
the programmable analog output maps the ass gned parameter.
The temperature nputs can be used to control the temperature
of the transformers w nd ngs, motors.
There s a galvan c separat on between follow ng un ts of the meter:
- supply
- voltage nputs
- current nputs
- RS485 nterface
- Ethernet nterface
- alarm outputs
- analog output
- temperature nput Pt100

3 BASIC REQUIREMENTS, OPERATIONAL SAFETY
In terms of operat onal safety the controller meets the requ rements of the
EN 61010-1 standard.
Remarks concern ng safety:
The meter should be nstalled and connected only by a qual f ed
personnel. All relevant safety measures should be observed dur ng
nstallat on.
Always check the connect ons before turn ng the meter on.
Pr or to tak ng the meter hous ng off, always turn the supply off and
d sconnect the measur ng c rcu ts.

ND30-09D 4 User's manual
Removal of the meter hous ng dur ng the warranty per od vo ds the
warranty.
Th s meter conforms to all requ rements of the electromagnet c
compat b l ty n the ndustr al env ronment.
A sw tch or a c rcu t-breaker should be nstalled n the bu ld ng or
fac l ty. It should be located near the dev ce, eas ly access ble by the
operator, and su tably marked.
4 INSTALLATION
The meter s ntended to be f xed to the panel w th mount ng brackets as
presented on F g. 1. The meter hous ng s made of a self-ext ngu sh ng
plast cs.
Fig. 2. Meter fitting
Hous ng overall d mens ons 96 x 96 x 77 mm, d mens ons of the assembly
hole 92.5 x 92.5 mm. There are screw term nal str ps on the outer s de of
the meter wh ch enable the connect on of external w res of d ameter up to
2.5 mm2.

5 METER DESCRIPTION
5.1 Current nputs
All current nputs are galvan cally solated ( nternal current transformers).
The meter s adapted to work w th external measur ng current transformers /
1 A or 5 A /. D splayed current values and der vat ve values are automat cally
converted n relat on to the ntroduced external current transformer rat o.
5.2 Voltage nputs
All voltage nputs are galvan cally solated ( nternal transformers). Values on
voltage nputs are automat cally converted accord ng to the ntroduced rat o
of the external voltage transformer. Voltage nputs are spec f ed n the order
as 3x57.7/100 V, 3x230/400 V or 3x110/190 V, 3x400/690 V.
5.3 External connect on d agrams
