2.General Information
2.1. Warning and Information Signs
One or more of presented symbols can be used in the user’s manual:
Caution: pay special attention to the
description in the analyzer user’s manual.
Terminal of the protection lead
Earth terminal
Protection of sensitive electrostatic systems
(ESD)
2.2. Operating Safety
In the safety operating scope, the ND1 Power Analyzer meets requirements
related to safety of electrical measuring instruments for automation, acc. to EN
61010-1 standard and requirements concerning the immunity against noises
occurring in industrial environments acc. to EN 61000-6-2 and EN 61000-6-4
standards.
The improper connection of the supply, communication interfaces and measuring
signals, and the use of equipment inconsistent with the description included in the
present user’s manual and standards as above, can cause serious damage of the
analyzer.
2.2.1. Remarks Concerning the Analyzer Installation
Various sources of noise occurring in practice interact with the ND1 Power
Analyzer in a continuous or pulse way from the supply network side (as the result
of the action of other devices) and also overlap on the measured signal or auxiliary
circuits of the analyzer. Noises occur also when switching capacitive-inductive
loads by own analyzer alarm relays.

9
In particular, strong pulse noises are dangerous for the device operation since
they can cause sporadic erroneous measurement results or accidental operations
of alarms. The level of these noises should be reduced to a value lower than the
immunity threshold of the analyzer, first of all through a suitable installation of the
analyzer in the object.
In this scope, it is recommended to observe following recommendations:
Do not supply the analyzer from networks near devices generating high
pulse noises in the supply network and do not use common grounding
circuits with them.
Signaling wires must be shielded.
Lead connections of binary input circuits, individually in shields as above,
by means of twisted wires.
Connections of communication interface circuits, lead individually in shields
as above and by means of twisted wires.
All shields should be earthed unilaterally near the analyzer.
A common earth conductor with other devices must be avoided.
Apply the general principle that wires (group of wires) leading different
signals should be led in the longest possible distance between them and
crossings of such groups of wires should be made at a 90° angle.
When connecting the supply, please remember that a switch or a circuit-
breaker should be installed in the room. This switch should be located near
the analyzer, easy accessible by the operator and suitably marked as an
element switching the analyzer off.
It is not allowed to remove the analyzer casing.
All operations concerning transport, installation, and commissioning as well
as maintenance, must be carried out by qualified, skilled personnel, and
national regulations for the prevention of accidents must be observed.
Protections ensuring the device safety can be less effective in case of
exploitation inconsistent with manufacturer’s indications and principles of a
good engineering practice.

10
2.2.2. Precautions in the ESD Protection Range
Semiconductor elements or packages used in the analyzer design and marked
with the sign as above, can be damaged in result of electrostatic discharges
(ESD).
In order to prevent this, you must observe following recommendations during
service works:
Disassemble instruments only in the area protected against electrostatic
discharges.
Use conductive materials to dissipate electrostatic charges in the working
area.
Use only antielectrostatic packings to store electronic elements and
packages.
Do not touch elements and packages with hands.
Do not keep materials susceptible to generate electrostatic charges in the
working area.
Repairs and modifications in the device
equipment should be carried out by
authorized service workshops or with the
manufacturer.

3.Preparation of the ND1 Analyzer to Work
The analyzer with accessories is delivered in packing fulfilling requirements of
environment protection regulations.
The analyzer in the shipping packing can be transported and stored in the
temperature -20 ....+65ºC (-4 ...149ºF).
3.1. Unpacking
A. Take the ND1 analyzer out from the shipping packing.
The data plate with the version code, factory number and supply parameters are
placed on the analyzer casing. Before unpacking, check the conformity of the
device version with the order.
B. Take ND1 analyzer accessories out from the transport packing.

3.2. Installation in the Panel
Fig. 3.1. Analyzer installation in the panel
Put the seal from standard accessories on the casing (see section 3.1). After
mounting the analyzer into the panel, the seal protects the part behind the panel
against the influence of risks appearing from the frontal part of the panel, resulting
from the IP65 protection grade. The analyzer is fixed to the panel by means of four
screwed mounting brackets from the standard accessory set (see section 3.1.).
Basic fixing and panel cut-out dimensions are presented on the above figure.
3.3. Analyzer Operating Conditions
The analyzer can work at ambient temperature: 0...+50ºC (32 ...122ºF) and
max.75% of relative air humidity without condensation (or at 0...+65ºC and max.
40% RH without condensation).

Fig. 4.2. Touch screen
All elements of the user’s interface (windows, icons, buttons) have dimensions
adapted to be easily handled by fingers –They do not require special tools.
After mounting the analyzer into the panel, remove the foil protecting the external
flexible layer of the touch panel if exist.
Considering the sensibility of the touch panel to dirt and external damages of its
surface and the substrate, observe the following recommendations:
protect against impacts, they can damage the external surface or the glass
substrate of the touch panel,
protect against fluids, grease and aggressive chemical agents,
touch the screen with fingers only, do not use hard and sharp objects which
can damage the flexible surface of the touch panel,
clean softly with a cotton cloth impregnated with a detergent destined to
clean LCD monitors (not containing alcohol, petrol or ammonia ) or by using
water with soap,
observe the given temperature range of the analyzer operation.
Since there is a possibility of an image persistence effect on an LCD screen (after
a prolonged display of a constant figure), as default the screensaver (the blank
screen) is set for 15-minute timeout (after continuous work without touching the
screen). The screensaver is gone when the screen is touched any place. The
timeout can be changed or this function can be switched off completely (see
section 7.1.2.).

4.2. CompactFlash Memory Card, USB Interface, LED Diode
A CompactFlash card with capacity up to 4 GB is dedicated to a measuring data
support. It is recommended to apply CF cards produced by SanDisk® company.
Current measuring data, archive data and analyzer configuration files are stored
on the CF card
Fig. 4.3. Frontal view of the analyzer after opening the door
You can download data from the CF card to a PC through the USB interface. You
can also save or delete selected files on the card. To connect the computer to the
analyzer through the USB socket, use the shielded USB AM-BM cable of 1.8 m
long (delivered in standard accessories) or another similar of maximum 3 m long.
To gain access to the ND1 analyzer data thru USB interface on a PC with
MS Windows operating system it is necessary to install drivers and the
KD Connect program from the accompanied CD. It is delivered with the analyzer
accessories (for the description and program installation, see section 9.1).

4.3.1. Mounting of the Power Supply Filter
In order to fulfill EMC requirements, one must always apply the delivered power
supply filter when connecting the supplying wire to the analyser.
To mount the power supply filter one must reeve all the three supplying wires
(L,N,PE) through the filter core, creating a full loop around it (Fig.4.4).

Description of Ethernet socket diodes:
Yellow diode: lights when the analyzer is
connected to the Ethernet network and does not
light otherwise.
Green diode: Tx/Rx, lights irregularly when the
analyzer uploads and collects data from the
network and lights.
Lead functions of the RJ45 socket are in compliance with the EIA/TIA 568A/B
(AT&T258) standard. To connect the analyzer with the hub (concentrator) or the
switch, you have to use a cable with leads 1:1, according to the description as in
the above figure. To the direct ND1 connection with the PC, use a crossed cable:
