2. Preparation for Installation
52
Ensure that the capacity for incoming current to the distribution board
is greater than the operating current of the circuit breaker. If it is not,
the circuit breaker might not operate properly in the event of a failure,
which could result in fire.
NOTE
Generally, the breaker operating current is greater than the rated
current. Check the specifications of the circuit breaker.
In addition, when a Switch is turned on, inrush current shown in the figure below
flows. Consider measures for avoiding a voltage drop in the power supply facility
caused by the inrush current.
Table 2-5 Inrush current
Current Time
30 A 150 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.
2.4.2 Power supply facility for 200 V AC
(1) AC power cable
An optional 200 V AC power cable is available that allows the Switch to be used in a
200 V AC environment.
For information about the 200 V AC power cable, see 1.9 Power cable.
NOTE
If an optional ALAXALA power cable cannot be used with your power
facility, use a power cable that meets the following ALAXALA
specifications.

When using a Switch in a 200 V AC environment, use only the
separately sold ALAXALA power cable, or a power cable that meets
ALAXALA specifications. Using another cable could result in fire or
electric shock. In addition, do not use the supplied power cable with
another switch. Doing so could result in fire or electric shock.
