Power Cabling

The figure below depicts the elements of a power supply device:

Figure 74.

Power Equipment Elements

Since power is applied to the system where the power cable is connected by

manipulating the circuit breaker of the rectifier, ensure to check the rectifier

breaker is turned off (open) before connecting the power cable to the power

connector. If the system is installed while the circuit breaker is on, the worker may

get critically injured if the cable is connected in the wrong way.

Handling the power cable incorrectly may damage the rack or cause an electric

short-circuit through the cable. Ensure the power switch of the rectifier or the

system is turned off before handling the power.

The fasteners for power cable must be tightly secured to prevent electrical

accidents.

The heat-resistant temperature of the power cable should be 90°C or more.

Install the power cable to the power port of the system by considering the radius of

curvature of its cable specification and then cut the cable. If the operator installs

the cable after cutting, there may be length difference among the core wires at the

end of the cable because of cable curvature. This may result in poor contact after

the cable is connected to the power port.

If you turn the power on and off rapidly (within 1 s), the counter electromotive

force caused by cable inductance can damage the system.

Connecting more than one power cable together may increase power loss.

It must be verified that the rectifier or the power distributor has an output voltage

within the specified system input range before the power line is connected.

If using the DC power cable, the maximum installation length per type is as

follows. Note, however, that the maximum installation length is based on the

conditions under which each cable is normally installed and that it may change if

the conditions change.
