5 Advanced Metering Infrastructure Code (AMI) Amendment to the Regulations for the Installation of Electrical wiring to accommodate the Advanced Metering Infrastructure (AMI) components Additional Field Requirements for AMI In addition to Kahramaa Installations regulations, the below shall be considered for Advanced Metering Infrastructure system (AMI); additional Drawing named Advanced Metering Infrastructure Layout shall become a part of the Building Permit document submission for Kahramaa approval. A. Multi meter case for MSB connection / Multi meter case for LV panel 1) In each / typical floors, provide Two embedded 32 mm PVC conduit (2 nos. x 32 mm) between each group Electricity meters of (max 12 meters) and the corresponding group of Water meters (Between both groups) with pulling and the following embedded es (provide access panels on false ceiling, if required). a. In electricity metering room near to the Main Distribution Board, install 2 Nos. 150mm x 150mm x 100mm size end to connect with the 2 No.s 32 mm PVC conduits. b. In water metering room near corresponding Water meter cabinet, install 2 Nos. 150mm x150mm x 100mm size end to connect with the 2 No.s 32 mm PVC conduits. c. Install 32 mm conduit to connect the above 2 Nos. end Boxes at water metering room (in item b above) to corresponding water meters cabinets Up to 3 cabinets maximum, each of the 2 nos. end es should be connected to each water meter cabinet (when cabinet does not exist stop at group of meters with 150x150x end ) and all conduits should have a pulling (every cabinet suppose to have 4 meters only). d. For every conduit; Install pulling es in every 10-15mtr distance / corner portions. 2) Provide 1 x 32 mm embedded heavy-duty PVC conduit with 5c. 2.5mm 2 cables (R, Y, B, N & E) for interconnecting power supply between the main water meter chamber and nearest ground floor electrical room / LV room and Provide another 1 x 32 mm embedded heavy-duty PVC conduit between the main water meter chamber and The MDF with pulling with the following embedded es: (Pr waterproofing is required for the conduits in main water meter chamber and building retaining wall) a. Install IP65, 150mm x 150mm x 100mm size end near to the Main Distribution Board / LV panel in ground floor electrical room with a 32 mm PVC conduit connecting with pulling at Main LV panel and Install IP65, 150mm x 150mm x 100mm size end near to the MDF. b. In main water meter chamber, install 2 nos. IP65, 100mm x 100mm x 50mm size end on high level and ensure the connection to the 2 nos. 32 mm heavy duty conduits mentioned in point 2 above. c. Install pulling chamber / in every 20-25mtr distance / corner portions. 3) In main LV room a 500mm (Height) x 500mm (Width) provision required on the wall with 100mm x 100mm x 50mm size surface mount type for each data concentrator (AMI Device);. Following additional requirements are to be incorporated. a. Install embedded conduit with 5c. 2.5mm 2 cables (R, Y, B, N & E) from the LV panel-metering compartment to the data concentrator on the wall. Each data concentrator requires a 3ph+N supply from the respective main LV panels, each LV panel will have a Data Concentrator. b. Distance between the data concentrator es shall be minimum 300mm, if two or more main LV panels are in the main LV room. Page 04 of 08

6 4) Provide embedded 38mm PVC conduit for between the MDF panel and main LV rooms with pulling and the following embedded es (provide access panels on false ceiling, if required). a. Install 150mm x 150mm x 100mm size end 30 cm from MDF. b. Install 150mm x 150mm x 100mm size end in main LV room, near to data concentrator. c. In case of more than one concentrator in main LV room (More than one Main LV panel), install 100mm x 100mm x 50mm size near to each data concentrator and install and connect 25 mm conduit between these 100mm x 100mm x 50mm size es and the 100mm x 100mm x 50mm size end in main LV room. d. Install embedded pulling es in every 10-15mtr distance / corner portions. B. Service Cabinet / Electric room connection / Single meter case for MSB / Single meter case for LV panel connection 1) Provide 2 Nos. embedded 25mm PVC conduit between the electrical and water metering cabinets and fix at allocated opening in both cabinets of respective premises (use pipe/cable entrance only in case of no allocated opening) with pulling and install IP65, 100mm x 100mm x 50mm size embedded pulling es in every 20mtr distance / corner portions. 2) Provide 1 Nos. embedded 25mm PVC conduit between Landlord water meter and Landlord Electric meter locations with pulling and install IP65, 100mm x 100mm x 50mm size embedded pulling es in every 20mtr distance / corner portions. Note: In all cases; Distant from relevant eclectic meter should not exceeds 90 meters. Page 05 of 08
