3.3 Cascading Power
When installing multiple
Multi-Power Miniature
Media Converter
10/100/1000 units on a
DIN rail, connect to one
DC input source and then
cascade from one DC
block to the next, until
reaching the maximum
electrical current available.
3.4 DC Power Supply Precautions
The following precautions should be observed when installing chassis with
DC power supplies.
1. Check
nameplate
ratings to assure there is no overloading of supply
circuits that could have an effect on overcurrent protection and supply
wiring.
2. When installing 7 to 50VDC rated equipment, it must be installed only
per the following conditions:
a. Connect the equipment to a 7 to 50VDC supply source that is
electrically isolated form the alternating current source. The 7 to 50V
DC source must be connected to a 7 to 50VDC SELV source.
b. The maximum terminal voltage is 50VDC.
c. Input wiring to terminal block must be routed and secured in such a
manner that it is protected from damage and stress. Do not route
wiring past sharp edges or moving parts.
d. A
readily
accessible disconnect device, with a 3mm minimum
contact gap, shall be incorporated in the fixed wiring.
3. Grounding:
reliable
grounding of this equipment must be maintained.
Particular attention should be given to supply connections when
connecting to power strips, rather than direct connections to the branch
circuit. The Negative Terminal is common to the grounded case.
