Planning for Power Requirements
Note Some of the power supply modules have rating capabilities that exceed the switch requirements. When
calculating your power requirements, use the switch requirements to determine the amount of power that is
required for the power supplies.
To minimize the possibility of circuit failure, make sure that each power-source circuit that is used by the
switch is dedicated to the switch.
Note For AC input application, please refer to the following statement:
Warning Statement 1005 Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the
protective devices are rated not greater than 20A (North America), 16A (Europe), and 13A (UK).
Note
For DC input application, please refer to the following statement:
Warning
Statement 1005 Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent) protection.
• Ensure that the protective devices are rated not greater than 70A when the switch is powered with regular
DC power supplies (rated 48-60VDC).
• Ensure that the protective devices are rated not greater than 15A when the switch is powered with HVDC
power supplies (rated 240-380VDC).
Warning
Statement 1033
Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV)
requirements in IEC 60950 based safety standards.
Note We recommend 8-AWG wire for DC installations in the U.S.
