1.4 Cable Layout
When cables are used in a high temperature environment, the insulation layer may age
and be damaged. Ensure that a sufficient distance exists between the cables and the DC
busbar, shunt, and fuse.
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 Figure 1-1. Ensure that the wider
end of the frame is at the bottom, the base cannot slide, and that the ladder is securely
positioned.
