Ensure that circuits are sized according to local and national codes.
For North America, the 300-W power supplies require a 20-A circuit. If you are using a 200- or
240-VAC power source in North America, the circuit must be protected by a two-pole circuit
breaker.
To prevent loss of input power, ensure the total maximum loads on the circuits supplying
power to the switch are within current ratings for wiring and breakers.
As you install and configure the switch, record the information listed in the
Maintenance Records" section on page
