2. Preparation for Installation

NOTE

Generally, the breaker operating current is greater than the rated

current. Check the specifications of the circuit breaker.

In addition, if a Switch is turned on, the inrush current described in Table 2-12 Inrush

cur

rent flows. Consider measures for avoiding a voltage drop in the power supply

facility caused by the inrush current. Be especially careful, when using a UPS or

CVCF.

Current Time

80 A 40 ms

CAUTION

When a Switch is turned on, inrush current flows. Consider measures

for avoiding a voltage drop in the power supply facility caused by the

inrush current. Voltage drops affect not only the Switch, but also the

devices connected to the same power supply facility.

NOTE

The inrush current described above is the value for a single power

supply unit.
