Data from these meters is used to analyse historical trends, determine flow rates and peak demand, discover and trace energy performance issues and leaks, monitor power factors, and generate utilities billing for UNSW tenants. As a general rule, metering for electricity, gas and water (both potable and bore water) is required for new buildings and/or major plant items, specific services, user groups and tenants. This section of the UNSW Design and Construction Guidelines covers the following topics: Documentation, Approvals and Checklists for new installations and changes to existing meters or the metering network architecture. Meter Data Communications Network Electricity Meters Water Meters Gas Meters The notes that follow provide the minimum technical requirements that shall be incorporated into any proposal to supply and install or maintain meters and associated metering equipment at UNSW premises. Tenderers and Contractors installing or maintaining approved meters and associated equipment shall connect or incorporate them into the existing EMACS to provide full functionality and remote monitoring capability. Only competent and approved contractors shall be permitted to install metering at UNSW. The final step in the integration of a new meter into the system involves software tasks within the EMACS program itself. This work is normally undertaken either by UNSW in-house or by a Contractor specifically assigned to this task by UNSW. Unless otherwise specified, this final step does not fall within the scope of work for installations covered by these requirements. 2/03/2015 Page 4 of 47 A7.2 INTERPRETATION AND COMPLIANCE WITH NCC PART J8.3 FACILITIES FOR ENERGY MONITORING For new and refurbished buildings UNSW requires that appropriate utilities metering, compliant with this guide, be installed to measure the total building use of electricity, gas and water. In addition, sub-metering is to be installed to measure total energy use of the building’s mechanical services installation, split into essential and non-essential elements. In certain cases additional metering may be requested to measure specific equipment or plant of special interest to Facilities Management such as the supplies to retail tenancies or to record the import/export of energy from PV systems or trigeneration installations. UNSW is fully aware of the deemed-to-satisfy Provisions of the Australian National Construction Code (NCC) 2013, J8.3 which states that a building “….must have the facility to record individually the energy consumption of……” which some consultants and contractors have interpreted as a requirement to install sub-meters on every distribution board separately for power and lighting plus the installation of sub-meters for additional energy systems as listed in the code. However, UNSW does not interpret the phrase “… must have the facility to record….” as a de-facto requirement that a sub-meter must be installed to comply. If this were the case, then the regulation would have mandated this in plain terms. The UNSW interpretation is that a “…facility to record…” implies that a provision is made which facilitates the attachment of a meter, data logger or some other recording device in order to measure energy use in the sub-systems as specified should it be required at some time. This could include fitting of CT’s only, or providing suitable space within switchboards and distribution boards where portable recording devices can be readily installed. Therefore, UNSW does not require or approve design proposals in which a plethora of energy sub-meters are proposed, in excess of those stated above, as a response to the requirements of J8.3. Our requirement is for designers to incorporate only a “…facility to record…” those energy systems and elements as specified in the NCC. A7.3 DOCUMENTATION AND APPROVALS Documentation The following are the minimum documentation requirements for the installation and connection of meters and associated equipment to EMACS. Data Forms a) Meter Data Forms are required to be completed whenever: A new meter is added – full details are required, e.g. location of meter, description of the load, description and meter model, serial numbers, etc.; An existing meter is replaced – meter details are required to be updated, e.g. serial number, existing meter reading, etc.; A meter is relocated – updated location and meter reading before being moved; A meter is disconnected and removed – a final meter reading should be taken; and 2/03/2015 Page 5 of 47 The load on a meter changes substantially – e.g. additional pipework, cabling, DB loads, etc. are added to the metered system. A meter data form shall be completed and submitted to the Energy Manager for approval before any work is carried out. One form is required for every meter and specific meter data forms are to be used for electricity, gas or water meters. When approved, a unique meter identification number is allocated to each meter by UNSW Energy Management. This enables accurate tracking of each meter as well as identifying the meter on the EMACS. b) Programmable Logic Controllers (PLC’s) and Ethernet Gateways (ETG’s) forms, are required to be completed whenever: A new PLC or ETG is added – full details are required, e.g. location, description PLC/ETG, communication details, serial numbers, meters connected to PLC/ETG, etc.; A meter is added, relocated or removed – generally electricity meters are connected to ETG’s and water/gas meters are connected to PLC’s so if the meter changes then so does the communications chain for ETG’s or the PLC inputs; An existing PLC or ETG is replaced – details are required to be updated, e.g. serial number, etc.; A PLC or ETG is relocated – updated location; and A PLC or ETG is disconnected and removed. Completed examples of the Meter Data Forms and the PLC/ETG Data Forms can be seen in sections A7.14 and A7.15 respectively. Schematics The Energy Management unit maintains campus wide metering installation schematic drawings for electricity, gas and water services. The schematics depict where in the supply network a meter is installed, what loads are being metered and the relationships between adjacent meters. There are separate drawings for the: Electricity Meter Schematics – based upon the Campus wide Single Line Diagrams (SLD) incorporating the High Voltage feeds onto the Campus down to Low Voltage Distribution Boards. Gas Meter Schematics – based on the gas pipework throughout the Campus including a pictorial representation of the equipment or loads that each gas meter measures. Water Meter Schematics – based on the potable water pipework throughout the Campus including a pictorial representation of the equipment or loads that each water meter measures. Bore Water meters are shown, however the bore water reticulation system is currently being prepared. Communications Network Schematics – a comprehensive representation of the EMACS communication network with all relevant information related to a device (meter, ETG or PLC) and how it is connected back to EMACS. This ranges from the EMACS’s servers connected to the EMACS’s own private Virtual LAN (VLAN11) which is connected to the PLCs/ETGs down to each device (meters, ETG’s and 2/03/2015 Page 6 of 47 PLC’s). NB it is important that the correct order of devices on each serial RS485 network is shown as this will be reflected on EMACS screens. Whenever changes are made to the metering installation or communications network, installers or maintenance contractors are required to update or create the schematic drawings accordingly. Samples of each of the schematics can be seen in sections A7.16 through to A7.19. Checklists and Check Sheets To assist contractors with the important steps in either the installation or the commissioning of the meters and associated communications, a checklist (of actions to be undertaken) and a check sheet (to validate the installation) have been prepared and completed for each meter type. The commissioning process is vital in ensuring that the meter is measuring the load accurately and EMACS is displaying the data correctly. Examples of the checklists and check sheets can be found in sections A7.9 through to A7.13. After commissioning the Contractor shall supply an individual calibration certificate for each meter showing details of the meter, the results of the calibration test and the date the calibration was carried out. Approvals Approval from the Energy Manager is required before the installation of any new meter, or changes to the EMACS system, is proposed. The approval and documentation process is as follows: 1. The contractor completes the relevant sections of the Meter Data form and forwards it to the UNSW Energy Manager; 2. The Energy Manager will approve/decline the proposal, assign a meter identification number and return the form to the installer; 3. The meter is installed in accordance with this UNSW Metering Design Guide and any special conditions that may be noted by the Energy Manager on the Meter Data Form; 4. When the installation is complete the installer advises the Energy Management Unit by email [email protected] - and provides further information, such as, the initial meter reading and the meter serial number; 5. The relevant meter schematic shall be updated and submitted for approval; 6. The checklist and commissioning check sheets shall be submitted as proof of the correct install process, including any supporting equipment documents such as meter calibration sheets. 7. For gas meters, the contractor shall also provide documented proof of the hazardous area classification of the gas installation to support the method of installation of the gas meter to EMACS. For projects with more than 3 meters to be installed, it is also advisable that the design be approved by the Energy Manager from the beginning of the project to ensure that the correct type of meter is installed in the correct location. 2/03/2015 Page 7 of 47 A7.4 COMMUNICATIONS NETWORK The best way to connect a new electricity, water or gas meter to EMACS depends upon a number of factors. These include the quantity of meters; the location of the meters; the proximity to an existing Modbus network that is not already over-populated; proximity to a LAN port; available space to mount panels; etc. The notes below provide further information. The EMACS currently uses the CitectSCADA proprietary software platform which communicates over the UNSW's Ethernet Network infrastructure (via a Virtual LAN) with the field devices (PLCs, ETGs, Electricity, Gas and Water Meters) distributed throughout UNSW Campuses. The communication protocol between the EMACS and the meters is Modbus/TCP via a device called a Modbus to Ethernet Gateway (ETG). The preferred ETG is the ConneXium TSXETG100 ETG by Schneider Electrics which shall be configured to operate at 9600 baud. When a PLC is used, meters are connected by a localised Modbus (RS485) network in a daisy chain configuration. The last device connected to the daisy chain shall have a 120ohm terminating resistor connected across its communication terminals. The preferred cable to use for the RS485 communications is a 2 twisted pair shielded grey cable from Belden (part number 9842). The maximum number of Modbus capable meters and PLCs connected to the same RS485 network shall be limited to 20 with an overall cable distance of no more than 1200m. In theory, the number of meters and the maximum distance that a Modbus network can handle is more, but due to the environment in which the meters are located (switch rooms and substations) the design shall be conservative. Where the requirement for Modbus connections is greater than 20, then additional ETGs shall be used. An installer may propose an alternative connection method to the Energy Manager for approval before installation commences. Several Modbus networks have been setup at various points around the Campuses, mainly at locations where there are clusters of electricity meters and PLCs. Each electricity meter or PLC must have a unique Modbus address to allow the EMACS to identify the device. Unless otherwise specified or approved by UNSW, all new PLC’s shall be Schneider Twido PLC’s having 14 digital inputs and 10 outputs as standard. The part number for the PLC is TWDLCAA24DRF and they require a 240VAC power supply. Communications is via the installation of the optional RS485 card, part number TWDNAC485T. If analogue signals are required, then an additional analogue input card, part number TWDAMI8HT, shall be installed. Where a new PLC is used to connect water or gas meters to EMACS the UNSW standard configuration shall be downloaded into the PLC. The only variation required to the standard configuration is that the PLC must have its Modbus address changed to the one allocated by UNSW Energy Management. Each EMACS PLC has a standard software structure that is normally copied from one to the next and amended to suit the particular circumstances. Generally the code consists of 2 cascading counters for each PLC digital input and in turn each counter is copied to a 2/03/2015 Page 8 of 47 memory word that corresponds to the Modbus register that EMACS reads. There are some variations on this: If there is an analogue input card required, e.g. for water pressure then the hardware and software needs to reflect this. For serially connected PLC’s there will be a Modbus address that has to be entered/changed For Ethernet connected PLC’s there will be a unique IP address to be entered/changed Internal documentation normally has the ID number each input is attached to. A backup of the PLC’s software coding shall be made and passed to the Energy Manager in case the PLC needs to be replaced or becomes corrupted. Each localised Modbus Network is connected to an ETG which is connected to an UNSW LAN port that has been configured for the EMACS VLAN. The LAN port configuration must be carried out by UNSW IT Services department. Each ETG is configured with a unique IP address allocated by UNSW Energy Management. Each new communication network shall have a Block Diagram drawing showing the communication paths as shown in section 7.21 below. The installer or contractor shall issue a communications connection plan to the UNSW Energy Manager during the design process and gain approval before construction proceeds. Where protection relays (Sepam) are used for the High Voltage Protection System within a substation, then a connection to EMACS shall be designed using the RS485 interface unit (ACE949-2). In this way, not only is metering information at each high voltage switch available for Energy Management, but also the status of the protection can be interrogated for planning and maintenance purposes. The preference is to incorporate any of the metering (Sepams, ION7650s, PM5350s, etc.) within this substation via the RS485 Modbus RTU network and then wired to a Gateway. By doing this, only one EPR isolation device is required (via a length of fibre optic cable) to connect to the UNSW LAN. 2/03/2015 Page 9 of 47 A7.5 ELECTRICITY METERS AND HV PROTECTION RELAYS The University uses several models of Digital Power Meters (DPM’s) to monitor power and energy throughout the campuses dependent upon the situation, e.g. at Substations, Buildings, Switch Boards, and individual loads when required. Additionally, HV protection relays (Sepams) in Substations are connected to EMACS in order to monitor their status and get important information in case of trip events. All new DPM shall be defined as scheduled in the table below. Contractors may propose alternative solutions if are of superior or equal quality than the meters listed. However, the contractor must gain permission from the Energy Manager beforehand. Level of Monitoring Type 1a – e.g. HV feeds, substations Type 1b – e.g. HV protections Type 2 – e.g. building totals Type 3 - building sub-levels or Mech. Services. Type 4 – tenants Type of Monitoring Power quality, transients, and energy Protection Systems Energy with detailed harmonics Energy with harmonics Revenue Manufacturer – Model Part No. Schneider – ION7650 Schneider – PM5560 M7650A0C0B5E0A0E METSEPM5560 SEPAM 1000 series 40 Schneider – PM5310 S10MD XXX JXXX XNT METSEPM5310 Schneider – PM5110 Schneider – iEM3200 METSEPM5110 iEM3250/3255 Schneider – PM3250 Schneider – PM750 Schneider – EM1350 PM3250/3255 PM750MG EM1350 Type 1a metering requires a dedicated power quality meter with logging and alarm capabilities for the purposes of monitoring and reporting power disturbances along with the standard meter functions of phase currents, voltages, power, etc. PM5560 meters shall be used as main meters in substations along with Sepam protection relays (see section E3.4.6 Protection System), when measurement of the current on neutral is required, and when detailed power quality monitoring is required. ION7650 meters shall be used on the HV feeders at a campus level. NB the parameters and CT class need to match the Meter class and be taken into account for the power quality analysis. Type 2 shall be preferably the PM5310, while for Type 3 meters the PM5110 should be used. The iEM3250 is also acceptable as a Type 3 when only energy information is required (i.e. not in Mechanical Boards). The advantage of the PM5310 is that it is supplied with four pulse inputs for connecting a limited number of adjacent water or gas meters. Type 4 meters shall be the PM3250 (or PM3255 when pulse inputs are required, both grandfathered), the PM750MG (grandfathered), or the EM1350 (pattern approved), as they can be used for tenant billing purposes. 2/03/2015 Page 10 of 47 Loads that may be required to be metered for energy monitoring purposes are as follows: i. ii. iii. iv. v. vi. The low voltage feed from each HV Transformer; Total building supply; Building total light and power load; Building total mechanical services load, both essential and non-essential; Large services such as risers; Individual Chillers above 500kWr capacity, shall be metered separately for the purposes of calculating their efficiency; vii. Sections of building that are used for tenant billing; viii. Areas of a building that have been identified by UNSW as having high energy use; and ix. Metering as may be required by other legislative codes of practice. Installation and Configuration of Meters All meter types shall be installed in accordance with AS 62053.22-2005 Class 0.5S in respect to the accuracy of the meters, the CT’s and any voltage transformers. All meters shall have an RS485 serial communication output (or Ethernet output) and communicate using the Modbus TRU network protocol. In new projects all DPMs should be installed in a dedicated metering section of the corresponding board. This facilitates troubleshooting and the manual reading of the DPMs. Meters shall monitor either single or three phase loads as appropriate and shall display and communicate (for each phase and in total) the following parameters: Phase and Line Voltage (VL-N, VL-L) Current (A) Current on Neutral (A) Frequency (HZ) Power (W, VA and VAr) Power Factor (lead/lag) Energy (kWhr) Demand (max/min kVA) THD current and voltage (L-L and L-N) THD and Individual Harmonics, current and voltage (L-L and L-N) Accuracy 0.5% of reading Accuracy 0.5% of reading Accuracy 0.5% of reading PM5560, PM7650 Accuracy 0.1% of reading Accuracy 1.0% of reading Accuracy 1.0% of reading Accuracy 1.0% of reading Accuracy 1.0% of reading PM5110, PM5310, PM5560, PM7650 For PM5110, PM5310, PM5560, PM7650 In the case of the Type 1 and 2 meters, the following Demand Calculation parameters are also required to be configured in the meter: 1. Demand Calculation Type: Not-configurable. Both Sliding Window and Thermal Exponential Calculations are available. The EMACS uses the Sliding Window Calculation. 2. Demand Sub-Period: Configurable. Set to 3 minutes. 3. No of Demand Sub-Periods: Configurable. Set to 5. 2/03/2015 Page 11 of 47 All meters shall be installed with approved terminal strips for data cables (where required), CT wiring and shorting links, power supplies, fuses or circuit breakers. CT’s shall be located in a viewable location so that the sizing can be confirmed. The set of terminal strip fuses shall be located adjacent to the meter to allow the safe testing of the meter and for isolation of the meter should it require to be replaced. The same shall apply for the location of the shorting terminals for the CT’s. The standard layout and label wording to be used can be found in Section A7.10 below. Preferably, all DPM’s shall be mounted in a separate metering panel within a reasonable distance from any Main Switchboard (MSB) to satisfy acceptable burdens. If this is not possible and meters are mounted in the MSB, they shall be located in their own separate compartment that is shrouded from any exposed live equipment, and protected to IP2x rating. Under no circumstances shall any meter be mounted on a compartment door such that a switch or circuit breaker is required to be turned off to allow access to the metering terminals. The height of the metering panel (or metering section of any MSB) shall be 300mm and 1800mm above floor level with a minimum of clearance of 500mm in front of the meter to any other equipment, wall or other obstruction. Each DPM shall be powered from an auxiliary 240VAC supply fed from the supply side of any individual circuit switches or circuit breakers. This supply must be isolated by the main switch or circuit breaker to the MSB or DB. Where a number of DPM’s are fed from the same section of busbar, (therefore they probably have the same potential levels) then one set of potentials can be used to supply those meters rather than individual potentials supplies. Consideration can be given to using the Schneider NSX breaker range for the metering rather than the individual circuit breaker, meter, CT’s & potentials. A checklist has been provided to assist the UNSW Facilities Engineer and the Contractor in ensuring that important installation requirements have been completed and signed off. Please refer to section A7.11 below. 2/03/2015 Page 12 of 47 A7.6 OTHER ELCTRICAL DEVICES In addition to electricity meters the university also installs protection devices on main switchboards. It is required that these devices are also connected to the EMACS network so that their settings, measurements and alarms may be remotely accessed. The method for connecting the device to the EMACS system will depend upon the model installed and reference shall be made to the manufacturer’s installation manual for details of how the device is to be connected. 2/03/2015 Page 13 of 47 A7.7 POTABLE AND BORE WATER METERS The University uses “pulse” water meters of several types to monitor the potable and bore water consumption throughout the University’s campuses at Campus, Building, Tenants, and Individual loads when required. Total potable and bore water consumption shall be metered in all buildings. Sub-meters shall be installed on significant plant and equipment. Sub-metering to major plant is also important where noting changes in water consumption assists performance appraisal, leak detection and malfunctions (e.g. in toilet blocks). Examples of where metering may be required are: cooling towers, laboratory non-potable water, reverse osmosis systems, irrigation, toilet flushing supplies and pure water treatment plants. The preferred meters are as supplied by the Elster Metering Pty. Ltd. with a pulse attachment suitable for connection to the UNSW EMACS. As a guide, a pulse quantity of 10L/pulse shall be used for Sub-metering, and 100L/pulse (0.1m3/pulse) for building gate meters and campus mains. There are two methods used to connect a pulse meter signal to EMACS: 1. PLC Digital Input – there are currently over 30 PLC’s installed around the campus, which can accommodate up to 14 inputs each. 2. Electricity Meter with Pulse Inputs – there are a number of electricity meters (Schneider PM5350) around campus that have pulse input capabilities. A 2 pair twisted cable shall be run from the PLC or electricity meter to the water pulse attachment. Care shall be taken that there is enough mechanical protection for this cable along its complete length, especially when the water meters are installed in garden beds. The water pulse attachment normally comes with a small length of 2C or 4C cable. The two cables shall be connected together in a small weatherproof junction box. Due to capacitance build up on long cable runs that affect the pulse attachment, if the nearest PLC or electricity meter is more than 30m away then a new PLC shall be installed. This PLC can be connected to EMACS either through an existing RS485 network or via a PLC Ethernet Adapter Module cabled to a nearby VLAN11 port. When a more accurate flow rate measurement is required, then a flow meter shall be connected to EMACS through an analogue input card of a PLC. Likewise, if the water pressure measurement is required then the sensor shall also be connected via the analogue input card of a PLC. The necessary modifications shall be carried out to the PLC programme to allow the monitoring of the analogue inputs by EMACS. When installing and commissioning a new meter, the pulse quantity signals shall be verified by taking a manual reading of the analogue water meter and then re-checking it after sufficient water has passed through the meter, e.g. after a week. The difference in the meter reading should correlate to the amount shown on EMACS. This will be used to determine the actual quantity per pulse to be used on EMACS. A checklist has been provided to assist the Contractor to ensure that the important steps have been completed and signed off. Please refer to A7.12 below. 2/03/2015 Page 14 of 47 A7.8 GAS METERS Diaphragm meters shall be used for all purposes across UNSW Campuses due to their accuracy, minimal maintenance and turndown ratios. Turbine meters shall not be used. However, where special circumstances arise that make it difficult to install a diaphragm meter then an alternative meter type can be proposed to the Energy Manager for approval. Each building shall be provided with a pulse type gas meter suitable for connection to UNSW EMACS system. Sub-meters shall also be installed on Tenants loads and all major gas consuming plant and equipment. Meters shall be sized for normal demand rather than maximum demand possible to ensure that small losses are identified. The volume per pulse shall be determined depending upon the size of the gas pipe and the proposed gas usage. Typical values are 0.01 m3/ pulse, 0.1 m3/ pulse, and 1 m3/ pulse. The preferred gas meters to be used are the Ampy Email meters. The gas flow model relationship is as follows: 3 Model 750 – up to 7.5m / hour 3 AL 425 – up to 12m / hour 3 AL 800 – 0.1 to 22m / hour 3 AL 1000 – 0.1 to 28m / hour 3 AL 1400 – 0.1 to 40m / hour Where a medium pressure supply (100kPa) exists, the meter shall be correctly sized by the meter supplier for the given pressure. The volume per pulse affects the resolution of the information displayed on EMACS, which can be critical for billing purposes or for the accuracy of the flow rate calculation. If a more accurate flow rate is required then a flow meter shall be connected to EMACS through an analogue input card of a PLC. As for the water meters, there are two methods used to connect a pulse attachment to EMACS: 1. PLC Digital Input – there are currently over 30 PLC’s installed around the campus, which can accommodate up to 14 inputs each. 2. Electricity Meter with Pulse Inputs – there are a number of electricity meters (Schneider PM5350) around campus that have pulse input capabilities. Due to capacitance build up on long cable runs that affect the pulse attachment, if the nearest PLC or electricity meter is more than 30m away then a new PLC shall be installed. This PLC can be connected to EMACS either through an existing RS485 network or via a PLC Ethernet Adapter Module cabled to a nearby VLAN11 port. Gas meters shall be fitted with automatic temperature and pressure correction equipment. Where this is considered to be uneconomic for the particular installation, then approval shall be sought from the Energy Manager to relax this requirement. In these cases, the inlet gas pressure (kPa) shall also be metered. The Contractor shall provide the assembly with an upstream filter and regulator to stabilise inlet pressure and downstream regulator with 2/03/2015 Page 15 of 47 discharge pressure to suit the equipment connected. A pressure test point shall also be provided after the regulator on both the inlet and outlet sides of the meter. Hazardous and Non-Hazardous Installation Requirements Due to the dangers of potential gas leak explosions, it is advisable that any installations involving gas metering, be classified as either hazardous or non-hazardous by competent and knowledgeable UNSW representatives or consultants. This would involve the participation of an accredited Hazardous Area person to act as a facilitator. This classification indicates the level of protection and equipment used in the installation. It is the contractor’s responsibility to obtain a written copy of this classification before performing any installation work. Non-Hazardous Installations If the gas meter and the area in the vicinity of the gas meter are deemed non-hazardous by UNSW then the meter’s pulse attachment connection is straight forward. The pulse attachment is normally supplied with a short length of 2C or 4C cable and therefore a small junction box mounted alongside the gas meter is required. The pulse attachment cable shall be connected inside this junction box to the 2 twisted pair cable that is run from the PLC or DPM with digital inputs. Hazardous Installations If the gas meter and the area in the vicinity of the gas meter are deemed hazardous then spark suppression measures need to be installed. After the meter’s connection point to the EMACS Communication Network has been determined, a 2 twisted pair cable shall be run from the PLC or DPM to the gas meter’s Intrinsically Safe (IS) Barrier. The IS Barrier shall be mounted in a standard junction box in a suitable location, see section A7.23 below. The cable is connected to the output relay contact of the IS Barrier Relay. As before, the gas meter pulse attachment is normally supplied with a short length of 2C or 4C cable. A small junction box shall be mounted locally to the gas meter to provide a connection point for the meter pulse output cable to the IS cable that runs back to the IS Barrier. This cable connection shall be carried out using a resistor configuration that utilises the IS Barrier’s fault detection function. The resistors enable short circuit and open circuit detection by the IS Barrier which generates an alarm. The cabling from the IS Barrier to the gas meter shall be identified as an IS installation, preferably using blue coloured screened cable. This cable is then connected to the input of the IS Relay. Care shall be taken to ensure there is mechanical protection for all cables within the hazardous area along their entire length. Commissioning The pulse quantity signals shall be verified by taking a manual reading of the gas meter and then re-checking it after sufficient gas has passed through the meter, e.g. after one week. The difference in the meter reading should correlate to the amount shown on EMACS. This should inform the actual quantity per pulse to be used on EMACS. A checklist has been provided to assist the Contractor to ensure that the important steps have been completed and signed off.

It is not intended to be all encompassing as every scenario will be different. Put an X in the check box when the checklist item has been addressed and add a comment where required. Checklist Item Have the hazards and potential risks of the installation been identified (SWMS)? Pass N/A Comment Does this meter satisfy one of the criteria of being either a major supply to the Campus, a building total or a significant building load? Has the Meter Data Form been filled in and approval given to proceed by the UNSW Energy Manager? NB This is the most important step as without this approval the meter will not be connected to EMACS. It will also give direction on what type of meter to be used. Does a shutdown or outage need to be organised to install the meter? Have the CT’s been sized according to the load and required burden? Has the best location for the CT’s, potential fuses, links and terminals been determined? Can the meter be installed on the MSB/DB/MSSB or does it require a new panel or can it be mounted in an existing meter panel? Where is the best location for CT shorting links? NB Shorting links maybe required in both the MSB and metering panel to ensure the CTs are never left open circuited under load, especially if cabling or a meter cannot be installed straight away. 2/03/2015 Page 22 of 47 Has the method of connection to the network been determined? Can it be connected to any existing RS485 chain or is a new ETG required? If a new ETG is required contact the Energy Management Team to determine the best location. Does a new data port need to be installed? Is the installation phase complete, i.e. meter, CTs, potentials, terminals, CT shorting links, comms, wire numbers, etc? Has the meter been configured, i.e. with CT ratios, Modbus address and the energy value reset? Commissioning – has the commissioning Validation Check Sheet been completed and EMACS can read the meter? Has an ID number been returned by the Energy Management Representative to enable labels to be made? Have all of the required labels been installed?
