Scope of Work : Supply of 1 no of Inverter panel as per given specifications.

A. INVERTER CONTROL PANEL:I .Inverter Drive Section:Specification: 3 Phase, 380 - 500 volts, 50 Hertz, inverter drive modules will all standard protections like fast acting fuses, line chokes, surge suppressors, over current, over speed, over temperature etc. Inverter should have standard drive features like adjustable speed ramp, remote/ local selection, inch, jog, forward/reverse functions etc.

Drive module shall be capable of supplying 150% of rated current for one minute.

Inverter drive should have these technical data:

1. Input Voltage : 380-500volt AC,50Hz2. Input frequency : 45-66Hz3. Output voltage : 0-415volt4. Ambient temperature : 50degree5. Continuous rated current : 200Amps6. Frequency resolution : 0.01Hz7. Switching frequency : 1 – 20KHz8. Keypad : Backlit Alphanumeric LCD display9. Analog Input : 2 numbers Programmable 4..20MA and 0 to 10V DC10. Analog outputs : 2 numbers Programmable output (4 ...20MA)11. Digital Output : 2 numbers ( contact rating 240V AC,6Amps)12. Motor to inverter distance : around 50 meters

The drive panel shall be suitable for operating one numbers 110KW, 415Volts, 3 phase 50Hz, motor. Inverter drive with all standard features and protections.

Panel:Main panel shall be floor mounted, free standing to be made of good

quality, dent free sheet steel, completely dust & vermin proof with IP44 protection, and suitable for front execution only. All cable entries shall be from the bottom side via removable gland plates. Copper bus bars, which may be used, shall be insulated with heat shrinkable PVC sleeves. All cables used inside the control panel shall be good quality ISI approved copper flexible cables with necessary insulation level. The panel shall be well ventilated through fan mounted at the top- side of the panel. Bottom side of the panel door shall be fitted with air filters. Panel shall be neatly painted, with ISI grade, Siemens /ABB grey shade.

1. Switch fuse unit : 400Amps - 01no.

3. Control protections : MCBs

4. Terminal Blocks : Power terminals should be suitable Bus bar type suitable for 3X240 mm2 AL termination

5. Control Terminations : AI/AO & DI/DO terminations are required at output

terminations with fuse fail indication TB

6. Chokes : 125% rating of Full load current of Inverter

7. Indication : ON – OFF – TRIP indication for each inverterin the front panel door.

8. Space Heater : Suitable as per dimension of panel.

9. Protection : IP 44

10. Metering : Multifunction meter ( Make: Trinity) 11. Push Buttons : Speed Inc. , Speed Dec , ON , OFF
