(2) Electrical outlet
Use the electrical outlet described below. These electrical outlets are available at general
electrical contractors.
Two-pole grounded twist-locking receptacle: 10 A/250 V
Make sure to connect the AC model to a grounded outlet. Not connecting the
grounded outlet to the switch can cause electric shocks, as well as cause failures
due to electrical noise.
(3) Distribution board
The branch circuit to supply power to the Switch requires circuit breakers or other devices.
When selecting circuit breakers, make sure that they meet the following rating,
considering the input current and inrush current/time.
 Breaker rating: 10 AT (single phase 200 V AC for a 10 A circuit) or less
For details about input current of the Switch, see 2.2.1 General installation conditions, and
for details about inrush current and time of the Switch, see Table 2-15 Inrush current.
