Safety Requirements in Maintenance and Repair
1. Before connecting or removing cables, turn off the protection switch of the
corresponding loop.
2. Place a warning sign indicating that the switch must not be turned on at the position
where the switch resides.
3. Use an electroscope of a proper voltage level to check whether the equipment is
energized and ensure that the equipment is completely powered off.
4. If charged bodies are found nearby, block or wrap them with insulation plates or
insulation tapes.
5. Before performing maintenance and repair, securely connect the loop to be repaired to
the ground loop using a ground cable.

Before connecting a cable, check that the labels on it are correct.

If the equipment has multiple inputs, disconnect all the inputs before working on the
equipment.
6. After the maintenance or repair is complete, remove the ground cable between the loop
that has been repaired and the ground loop.
Electrostatic Discharge (ESD)
The static electricity generated by human bodies may damage the electrostatic-sensitive
components on boards, for example, the large-scale integrated (LSI) circuits.

Wear ESD gloves before touching a device or holding a board or PSU.

When holding a board or PSU, hold its edge without touching any components. Do not
touch the components with your bare hands.

Package removed boards or PSUs with ESD packaging materials before storing or
transporting them.
1.6 Mechanical Safety
Hoisting

The foundation where hoisting is performed must meet the load-bearing requirements.

Before hoisting objects, ensure that hoisting tools are firmly secured onto a fixed object
or wall that meets the load-bearing requirements.

Do not drag steel ropes and hoisting tools or bump the hoisted objects against hard
objects during hoisting.

During hoisting, do not stand or walk under the crane or the hoisted objects.

Install temporary warning signs or fences to isolate the hoisting area.
