Follow the procedures described in the document for installation, operation,
and maintenance. Do not reconstruct or alter the equipment, add
components, or change the installation sequence without permission.
Obtain approval from the national or local electric utility company before
connecting the equipment to the grid.
Observe the power plant safety regulations, such as the operation and work
ticket mechanisms.
Install temporary fences or warning ropes and hang "No Entry" signs around
the operation area to keep unauthorized personnel away from the area.
Before installing or removing power cables, turn off the switches of the
equipment and its upstream and downstream switches.
If any liquid is detected inside the equipment, disconnect the power supply
immediately and do not use the equipment.
Before performing operations on the equipment, check that all tools meet the
requirements and record the tools. After the operations are complete, collect
all of the tools to prevent them from being left inside the equipment.
Before installing power cables, check that cable labels are correct and cable
terminals are insulated.
When installing the equipment, use a torque tool of a proper measurement
range to tighten the screws. When using a wrench to tighten the screws,
ensure that the wrench does not tilt and the torque error does not exceed
10% of the specified value.
Ensure that bolts are tightened with a torque tool and marked in red and blue
after double-check. Installation personnel mark tightened bolts in blue.
Quality inspection personnel confirm that the bolts are tightened and then
mark them in red. (The marks must cross the edges of the bolts.)
After the installation is complete, ensure that protective cases, insulation
tubes, and other necessary items for all electrical components are in position
to avoid electric shocks.
Keep the key to the medium-voltage equipment properly. The key can be used
only by authorized personnel.
Use instruments and meters in accordance with the regulations to avoid
electric arcs, short circuits, or other risks.
When operating the control panel of the ring main unit, ensure that you
stand on an insulated stool or ladder.
