(1) Standards for electrical outlets

Use the electrical outlets conforming to the following JIS or NEMA standard. These

electrical outlets are available at general electrical contractors.

Table 2-5 Standards for electrical outlets

Standards Specifications

receptacle

NEMA 5-15R

Figure 2-2 Two-pole grounded outlet (15 A/125 V)

Always use a grounded power outlet for the Switch. Failure to do so might not only

result in electric shock, but it might also introduce unwanted electrical noise that

could cause a Switch failure.

(2) 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.

 Rated breaking capacity: 15AT (for a 15 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 2-6 Inrush current.
