ROOTECH Accura 2300S/2350 User guide

  • Hello! I've reviewed the User Guide for the ROOTECH Accura 2300S and 2350 series power meters and measuring modules. This document provides detailed instructions on installation, operation, and setup, as well as information on device features like event logging, digital I/O, and communication interfaces. I'm ready to answer your questions about these products.
  • What voltages are considered dangerous while working with this device?
    What is the maximum torque for the barrier-type voltage terminal screws?
    What is the maximum torque for barrier-type digital inputs/digital output terminal?

Warranty Information
For products and software that are sold or licensed by Rootech Inc. during the period from the date
of receipt by you until the present, Rootech warrants only to the original purchaser
The purchased products shall be substantially free from material defects in material and workmanship

The software itself is provided as is without any warranty of any kind.
Limitation of Warranty
These limited Warranties shall not apply to any product that has been subject to alteration, accident,
misuse, abuse, neglect or failure to exactly follow Power Measurement's instructions for operation and
maintenance.
In order for the original purchaser to make a claim under the warranties described above, the original
purchaser must promptly contact Rootech headquarter. After receiving such notice, Rootech may either
in Rootechs sole discretion, examine the product at the original purchasers site or issue shipping
instructions to the original purchaser to return the relevant product to Rootech for examination at the
original purchasers expense, transportation charges prepaid.
If after examining the product Rootech reasonably confirms that such examined product does not
meet the warranties, then the original purchasers sole remedy and Rootechs sole obligation or
liability shall be, at Rootechs option, to repair, replace or refund the price paid for that product.
Regardless of whether any remedy set forth herein fails of its essential purpose, except to the extent

Chapter 1 Introduction
Overview
Energy Management Paradigm Shift from Main Load to Branch Load
Until now for stable power supply, energy management has been used for a long time on orientation
of mainly switchgear panels such as main feeder, ACB and VCB. however at the time of both the sharp
increase of energy cost and preparations for CO2 emission reduction policy, demand of energy
management on orientation of distribution panels which comprise incoming feeder and the branch
loads[or circuits] is increasingly growing in manufacturing plants, IDC center, building and etc.
Limit of Application of the existing Digital Power Meter to Distribution Panel
To apply the digital power meter which is long used in the existing switchgear panel to distribution
panel has had the limit caused by narrow space, hazardous wiring of voltage and current, and high
installation cost. This fundamentally makes it difficult for energy management supervisor to access to
the energy information of branch loads in distribution panel.
Distribution Panel Digital Power Meter Speicalized for Branch Load Management
Distribution panel digital power meter comprises both Apccura 2300S[digital power meter] which is
mounted on front of distribution panel, and Accura 2350[power measuring module] which is mounted
in branch loads inside the panel. Accura 2300S collects power data from several Accura 2350s on
RS485 communication and displays only measurements of one Accura 2350 selected on its LCD
screen. This provides energy management supervisor with the power quality information of branch
loads which was impossible to identify.
±0.2% Reading/IEC62053-22 Class 0.5S[Class 0.2S 1] Accuracy
Recently enterprise energy management system is essential for effective energy use and preventive
management to prepare CO2 emission management in plant, data center and building. The key
factor to determine reliability of the energy management is measuring accuracy. Accura 2300S/2350
makes 0.2% high accuracy measurements for voltage and current, and conforms to IEC62053-22
class 0.5S[Class 0.2S 1] for power and energy. This makes it possible to precisely analyze and
diagnose various problems with energy management and power facilities.

conforms to IEC62053-22 Class 0.2S.

Dip[Sag]/Swell[IEC61000-4-30 Class B], Power Quality
Accura 2300S provides various power quality information such as Dip[Sag], Swell, harmonic information [up to
63 harmonic], Crest factor, K factor, and unbalance. This makes it possible for energy management supervisor
to easily find the change of power quality in the power facility. Quality information conforms to IEC61000-4-30.
Aggregation Interval Maximum/Minimum/Average Information
Accura 2300S provides the average value that corresponds to 0.5 second interval from the
measurement value per cycle unit. Based on 0.5 second interval average value, Accura 2300S
provides the maximum/minimum/average of 1 second, 5 seconds, 1 minute, 5 minutes, 1 hour and
6 hours intervals. This measurement interval that is longer than 0.5 second means the Aggregation
Interval.
Accura 2300S provides not only the measuring parameter information, but also statistic information
(maximum, minimum, average) of voltage, current and power by communication. This includes the
information of measuring parameter which often changes. So this makes it possible to accurate trend-
analyzing about voltage, current and power.
CE/UL Safety and Reliability
The structure-framework, circuit, fire of Accura 2300S/2350 conforms to standard, CE[EN61326-1,
EN61326-2-1] and UL[UL61010-1].
Safety Guarantee of Installation by Through-hole Structure
Accura 2350-3P[1P] three phase[single phase] power measuring module is structured with Through-
hole current sensing without any electrical contacts, which guarantees safety of electrical accident and
simplifies installation. TM-3P is three phase terminal for helping wiring.
