Note: The wire gauge for the terminal block should be in the
range from 12 to 24 AWG.
Mounting
Important:
• Ensure that the industrial managed switch is mounted
vertically with the power connectors on the top and a
minimum of three inches above and below the switch to
allow for proper air flow. This device uses a convection
flow of hot air which rises and brings cold air in from the
bottom and out of the top of the device.
• Do not mount the switch horizontally as this does not allow
air to flow up into the device and will result in damage to
the switch.
• Do not tie DC1 to DC2. DC2 is for secondary power
redundancy.
• Do not plug DC power into the device while the AC power
cord is plugged in. This is not a hot-swappable switch.
Hot-swapping this device will result in damage.
