The 24VDC option is particularly useful in the industrial environment, where
it is common for facilities to operate on 24VDC power. The 24VDC applications are
mainly in heavy duty industrial automation such as factory floor, process plants,
HVAC, military equipment, etc.
B4.0 12, 24 and –48VDC INSTALLATION
This section describes the proper connection of the 12, 24, –48, leads to the
DC power terminal block on the LBH08x/LBH18x Switch.
The DC terminal block on
the LBH18x Switch is located on the right side of the unit and the LBH08x terminal
block is located on the left front and both are equipped with four (4) screw-down lead
posts. The power terminals are identified as positive (+) and negative (-), and they
are electrically floating inside the unit so that either may be grounded by the user if
desired. The chassis is “earth” or ground (GND).
The connection procedure is straightforward. Simply insert the DC leads to
the Switch’s power terminals, positive (+) and negative (-) screws. The use of Ground
(GND) connects to the Switch chassis screw provided under the DC terminal. Ensure
that each lead is securely tightened.
