Signal cables must be bound separately from strong-current cables and high-voltage
cables.
Cables prepared by the customer must have the fire resistance capability.
Cables must not pass behind the air exhaust vents of rectifiers in the cabinet.
1.5 Mechanical Safety
Hoisting Devices
Do not walk under cantilevers or raised objects.
Only trained and qualified personnel are allowed to perform hoisting operations.
Before hoisting objects, check that all hoisting tools are available and in good condition.
Before hoisting objects, ensure that hoisting tools are firmly fixed onto a weight-bearing
object or wall.
Ensure that the angle formed by two cables is less than 90 degrees.
Using a Ladder
Use only ladders that are in good condition. Find out and do not exceed the maximum
weight capacity.
The recommended angle for a ladder against another object is 75 degrees. Measure the
gradient with a right angle or your arms, as shown in
. Ensure that the wider
end of the frame is at the bottom, the base cannot slide, and that the ladder is securely
positioned.
Figure 1-1
Correct angle for ladders
When climbing a ladder:
−
Ensure that your body's center of gravity does not shift outside the legs of the ladder.
−
To minimize the risk of falling, steady your balance on the ladder before performing
any operation.
