INSTALLATION
Do s:
1. Floor levels are clean and ensure there should not be any
hardware / small equipment s below the panels.
2. Check all the components received are in proper condition.
3. Please refer O&M Manual for oor leveling.
4. Clean the panels using lint free cloths provided.
5. Use preferred Contact grease HBK83-102 as mentioned.
6. Use MOLYKOT 111 Compound/FOMBLIN GRM60 for
sealing purpose.
7. Use proper setting of torque wrench for tightening
hardware.
8. During panel movement ensure that copper rod, guiding pin
and lead screw are engaging properly.
9. Ensure all the hardware s are tightened properly.
10. Ensure all three B/B Plug-in conductor main are xed in the
panel during coupling only.
11. Ensure for equivalent movement of the panel from top and
bottom levels during coupling.
12. Ensure Earthing spring cord of all B/B Plug-in are properly
xed with the plate using M5 screw size.
13. Ensure the Arc Release Ducts chamber are not xed with the
panel during panel movement and coupling.
14. Keep proper vision and attention on the B/B Plug-in
conductor main alignment during coupling.
15. Check the alignment of earth bar during coupling of panels.
Don ts:
1. Handling of components without hand gloves.
2. Misalignment of bushings & busbar.
3. Using additional force during coupling (use only lead screw
or hydraulic jack as mentioned in O&M manual).
4. After applying MOLYKOT 111 Compound/FOMBLIN GRM60
to silicon plug, Don t Keep open to atmosphere more than
half an hour.
5. Fix B/B Plug-in conductor main with the panel during panel
movement.
6. Leave the B/B Plug-in conductor main with the panel after
xing it.
7. Leave the Earthing Spring Cord in hanging condition.
5.3.5 - Connecting the Earthing Bus
The earthing bus is provided at the lower back of each cubicle.
After the cubicle and busbar coupling is completed, connect the
earthing buses. The GIS is divided into unit cubicles as shown in
gure 5.3.5 and the earthing bus is likewise divided at the same
positions.
1) The earth terminal is provided at the left-end unit of the
cubicle array. Draw out the earthing wire from here.
2) Determine the earthing wire drawout position according to
the separate GIS oor plan.
3) The earthing wire should have a minimum of 180mm²
stranded bare hard copper wire.
4) Cable earthing shall be done on holes provided on earth bar.
5.4 - Connecting Control Wiring
1) The multicore cable termination for the control cable is
provided at the front on the right side. Connection should be
