Note
: The wire gauge for the terminal block should be in the
range from 12 to 24 AWG.
Mounting
Note:
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.
DIN-rail mounting installation
To replace the wall-mount application with DIN-rail application
on industrial gigabit Ethernet switch, refer to the following
figures to screw the DIN-rail on the industrial gigabit Ethernet
switch.
To hang the industrial gigabit Ethernet switch, follow the steps
below:
1. Screw the DIN-rail on the industrial gigabit Ethernet
switch.
2. Place the bottom of DIN-rail lightly into the track.
3. Ensure that the DIN-rail is secured to the track.
To remove the industrial gigabit Ethernet switch from the track,
carefully pull out the bottom of the DIN-rail to remove it from
the track.
