Power Cabling
The power supply device consists of the following elements:
Figure 35. Power Equipment Elements
Since power is applied to the system where the power cable is connected by
manipulating the circuit breaker of the rectifier, be sure to check the rectifier’s
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
be critically injured as soon as 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 on 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 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.
Install a circuit breaker to a rectifier (or power distributor) for the stable power. The capacity
of circuit breaker is 20 A or 25A. (Use UL Listed circuit breakers.)
