This document provides installation and commissioning instructions for an Integrated Power Management Unit (IPMU). The IPMU integrates a switch mode power supply and power management unit to provide power from the mains or generator to critical loads like a battery bank and BTS equipment. The summary includes: 1. The IPMU receives power from the mains or generator, regulates the voltage with transformers, and provides power to rectifier modules and battery bank. 2. Commissioning involves checking voltages and connections between the IPMU, generator, battery bank, and critical loads. Alarms are also connected from the IPMU and switch mode power supply to alert operators. 3. Detailed wiring diagrams and instructions are provided

IPMU
Introduction
IPMU is an integrated power management unit which integrates SMPS & PMU. The
concept of IPMU comes after development of switch mode power supply with wide voltage
operation. It reduces the application of large rating line condition unit and only low rating auto
transformer is required for air condition and lighting. It is well designed to send data of complete
site through SMS and GPRS.
Features:
1. It can work on 1 Phase, 2 Phase, and 3 Phase Mains.
2. If Mains Voltage is above 170V,it will directly feed to Rectifier Modules (RN.YN & BN)
3. If Mains Voltage is below 150V then Boost Voltage is supplied to the Rectifier Modules
Tools Required:
• Clamp meter with AC current meter and Probes.
• Crimping tool (6sqmm to 70sqmm).
• Drilling Machine with bits to take up to 15 mm
• Mechanical Tool Kit (Spanner set ,Wire Cutter & Screw Drivers set)
.

SITE READINES CHECKUP
• Ensure that site is ready for installation.
• Ensure that Mains Power is available at the site.
• Ensure that Battery Bank is installed
• Ensure that Generator Installed and commissioned
PRE INSTALLATION CHECKS:
Please check all Mains, Generator, Bat., BTS & Earth Cabling is done or do it as the
below mentioned.
• Lay the AC Cables from Mains Meter Box to IPMU with proper clamps & Cable Ties.
• Lay the Generator control cable from Generator to IPMU
• Lay the AC Cables from Generator to IPMU.
• Lay the (PE) Earth cable (16sqmm copper) is routed from Earth bus bar to IPMU.
• Lay the (TE) Earth cable (16sqmm copper) is routed from Earth bus bar to SMPS DC +ve
Bus bar in IPMU.
• Lay the cables (50sqmm Copper Red& Black) from Battery Bank to IPMU with proper
clamps & Cable Ties
Please check voltage across all the below mentioned points.
• Check Neutral to Earth Voltage by Multimeter in 20v Range, it should be 0 to 3V only.
• Check the AC voltage across RN, YN& BN.
• Check the Phase to Phase AC voltage across RY, YB & BR. It should not be Zero.
Note:
PMU is designed to work on Phase and Neutral. So it is necessary to check the neutral health before
installation. Proper earthing is also recommended in the site.
